Upgrade from 10.1.4 to 10.2

The guide describes the upgrade to the 10.2 version of WorkFusion Intelligent Automation Cloud Enterprise. Note that this operation uses the installer, so the procedure is similar to the installation.

Before you start

The 10.2 non-HA environment requires only five servers:

MASTER
AGENT
RPA
BI
DB

Note the following changes in server roles:

The separate INT, APP, and BEP Master servers no longer exist. Instead of them, we have introduced a single MASTER server. It contains all services, which were previously running on these three servers. In the case of the single-point installation, MASTER becomes the server to run the setup on.
BEP Agent servers are renamed to the AGENT servers/
Instead of a separate server, OCR Linux now runs on one of the AGENT servers in the same way as other workers.

Considering all the above, the upgrade starts with preparing the environment to bring the topology to the appropriate state.

Before the upgrade, ensure that:

No Business Processes or Manual Tasks are running.
You prepared fleets for migration.
You backed up the following components:
- Directories /opt/workfusion/workfusion and /opt/workfusion/wokspace.
- Vault properties for all components.
- Zookeeper settings that were changed since the last installation.
- Any system files that were changed since the previous installation.
You enabled SSH access to all Linux hosts.
You created the additional DNS record for Keycloak (See DNS names).
If SSO or LDAP authentication is enabled on the existing environment, verify that they are working before the corresponding component's upgrade.

Save fleet names for Bot Units

To save currently used fleet names for Bot Units, do the following:

Log in to Control Tower, and click Bot Manager.
In the Bot Manager UI window, click on your RPA server to expand the fleets.
Copy the value into the fleet column → Actions → Edit Fleet.
In the window that opens, click Create new, and paste the previously copied value.
Repeat these steps for all fleets.

Check running business processes

Before the upgrade, check that no business processes are running:

Go to INSTALL_DIR, where the installer directory was created during the installation of 10.1.4, for example: /opt/workfusion:
```
$ cd INSTALL_DIR
```

Check the output of following command:

./zookeeper/bin/zkCli.sh ls /control-tower/execution/active-instances | egrep -qo '^\[[0-9a-f-]+' && echo 'There are running business processes. Please stop them first to continue upgrade.' || echo 'There are no running business processes. You are OK to continue update procedure.'

If the command displays message "There are no running business processes. You are OK to continue update procedure.", you are safe to continue the upgrade. Otherwise, stop the running processes first.

Stop services

To stop services:

For single-point upgrade

For multi-point upgrade

Connect to the server with the previous installation package via SSH and run the following commands as <linux_installation_user>:

$ cd PACKAGE_DIR
$ export ANSIBLE_PRIVATE_KEY_FILE="<path_to_ssh_key>"   # Path to SSH key for connection to all Linux servers as WFUSER.
$ export ANSIBLE_VAULT_PASS="<ansible_vault_password>"   # Password for decryption of config.yml.
$ ./install.sh stop_services full

Connect to all Linux servers via SSH and run the following command as WFUSER on each of them:

$ wfmanager stop all

Prepare environment

Prerequisites

For 6-server environment

For 8-server or HA environment

Before upgrading IA Cloud Enterprise, make sure that your environment meets the following requirements. Failing to do so results in an extended time of the upgrade and may cause errors:

The environment must meet all the requirements that are listed in the System requirements section:
- Hardware and OS
- DNS names
  
  Make sure that you have created all domain names listed on the page.
- Ports
  
  Make sure that all ports listed on the page are open.
- RPA server
  
  Make sure that the required Bot Master and Bot Unit users are present on the RPA server.
- Database
  
  Also, make sure that your database has a user with the enabled db_owner role.
- Users and permissions
  
  Also, make sure that installation users on the Analytics and RPA server have either WinRM or RDP access.

Ensure that the environment has sufficient hardware resources.

As you will use the existing INT server as MASTER, upgrade your server hardware, if necessary. Note that the MASTER server uses more resources than INT. As you no longer need separate APP and BEP Master servers, you can use them as additional AGENT servers.
Ensure that shared folders are created and mounted correctly.

Skip this requirement if you use an external NFS server.

Shared folders INSTALL_DIR/vds-data and INSTALL_DIR/shared must be located on the MASTER server. For that:
- Move the above folders to the MASTER server with any convenient method.
- To share the folders via NFS and mount them to AGENT servers, either perform all root-related steps manually by following the guide or, if the WFUSER has the sudo privileges, proceed with the guide.
Before upgrading IA Cloud Enterprise, make sure that your environment meets the following requirements. Failing to do so results in an extended time of the upgrade and may cause errors.
- DNS names
  
  Ensure that all lb records (like marathon-lb.example.com) now point to the INT server's IP-address. Also, note that it is not mandatory to change the actual hostnames of servers. For example, if your current server has FQDN int1.example.com, you don't need to rename it to master1.example.com.
- Ports
  
  Ensure that all listed ports are open.
- RPA server
  
  Ensure that the required Bot Master and Bot Unit users are present on the RPA server.
- Database
  
  Make sure to create a new mssql_keycloak_user login in the database. Also, ensure that your database has a user with the enabled db_owner role.
- Users and permissions
  
  Ensure that installation users on the Analytics and RPA server have either WinRM or RDP access.
- Set the parameters and ports of the external load balancer, as described in Configure Load Balancer. Note that the load balancer must route all TCP traffic from the specified ports to the same ports on Master1, Master2 and Master3 servers (round-robin balancing between Master1, Master2 and Master3).

Prepare certificates

In 10.2, the server.crt certificate must mandatorily include the end certificate and all intermediate ones if they exist. Ensure that your certificates comply with the requirements.

Then, on the MASTER server, place prepared ca.crt, server.crt, and server.key to the PACKAGE_DIR/certificates/ directory.

Skip the step if you do not have them. In this case, self-signed certificates will be generated automatically during the installation.

$ ls -la PACKAGE_DIR/certificates/
total 24
drwxr-xr-x.  3 ec2-user ec2-user   78 Sep 24 14:47 .
drwxr-xr-x. 12 ec2-user ec2-user 4096 Sep 27 17:20 ..
-rw-r--r--.  1 ec2-user ec2-user 2984 Sep 24 14:42 ca.crt
-rw-r--r--.  1 ec2-user ec2-user 4835 Sep 24 14:42 server.crt
-rw-r--r--.  1 ec2-user ec2-user 1674 Sep 24 14:42 server.key

Verify prerequisites

After you prepare the environment for the upgrade, you can use the dedicated checking script for verification. For more information, see check readiness step.

Prepare installation directories

The preparation flow requires two folders on the MASTER server:

PACKAGE_DIR, where a new installer package is downloaded.
BACKUP_DIR, which contains configuration files from the previous installation.

Because of the different initial topologies and file placement, the approach to the flow may slightly differ.

For 6-server environment

For 8-server or HA environment

To download and extract the installer, connect to the server with the installation package from the previous version via SSH and run the following commands as WFUSER:

Go to INSTALL_DIR, where the installer directory was created during the installation of 10.1.4, for example: /opt/workfusion:
```
$ cd INSTALL_DIR
```
Create a backup directory (here, BACKUP_DIR) for the previous version of the installer. Ensure that the backup directory is writable for WFUSER:
```
$ mkdir BACKUP_DIR
```
Move the contents of your PACKAGE_DIR to the backup directory. As a result, directory PACKAGE_DIR must be empty before proceeding with the upgrade:
```
$ cd PACKAGE_DIR
$ mv * ../BACKUP_DIR
$ mv .agreement ../BACKUP_DIR
```
Stop the unnecessary OCR server, or prepare it for the AGENT role.

For IA Cloud v.10.2 in 6-servers environment, we do not use OCR as dedicated servers. For more details see the Hardware and OS section. Instead, you can use the existing OCR server as the AGENT one. For this, back up all directories and files from INSTALL_DIR and clean this directory after the backup.

If you do not want to use OCR as an AGENT server, you can stop them.

To prepare the installer, connect to the MASTER server via SSH and execute the following actions as WFUSER:

Make sure, that PACKAGE_DIR (for example: /opt/workfusion/wf_installer) and INSTALL_DIR exist on the MASTER server and are owned by WFUSER:
```
$ sudo mkdir INSTALL_DIR
$ sudo chown WFUSER:WFUSER INSTALL_DIR
$ sudo mkdir PACKAGE_DIR
$ sudo chown WFUSER:WFUSER PACKAGE_DIR
```
Go to INSTALL_DIR and create a backup directory (here, BACKUP_DIR) for storing the previous version of configuration files. Ensure that the backup directory is writable for WFUSER::
```
$ cd INSTALL_DIR
$ mkdir BACKUP_DIR
```
Move the following configuration files from PACKAGE_DIR on the previous installation server to the newly-created backup directory (BACKUP_DIR) on the MASTER server, with any convenient method:
```
license.properties
.agreement
rpa.yml
ports.yml
config.yml
hosts.yml
```
If PACKAGE_DIR on your MASTER server already contains previous installation package, move the contents of the existing PACKAGE_DIR to the backup directory. As a result, directory PACKAGE_DIR must be empty before proceeding with the upgrade:
```
$ cd PACKAGE_DIR
$ mv * ../BACKUP_DIR
$ mv .agreement ../BACKUP_DIR
```
Stop unnecessary servers, or prepare this for AGENT role

For IAC v.10.2 in 8-servers or HA topologes we dont use CT, BEP Master and OCR as dedicated servers. For more details see Hardware and OS section. You can use them as AGENT servers. For this you must backing up all dirrectories and files into INSTALL_DIR and clean this directoey after make backup. If you do not want use CT, BEP Master, and OCR as AGENT servers then just stop them.

Download installer

To download and configure the installer v.10.2:

Download the installer to PACKAGE_DIR:
```
$ curl -o '<10.2-installer-archive>' '<link-to-installer-10.2>'
```
If Internet access is not available on the server, download the package to the PACKAGE_DIR directory with any convenient method.

Extract the installer:

$ tar xzf <10.2-installer-archive> --strip 1

Copy configuration files for the current environment from BACKUP_DIR to PACKAGE_DIR:
```
$ cp -r ../BACKUP_DIR/{license.properties,.agreement} PACKAGE_DIR/
```
Generate new configuration files from existing ones:
```
$ export ANSIBLE_VAULT_PASS="<ansible_vault_password>"   # Password for decryption of config.yml.

$ cd PACKAGE_DIR
$ ./install.sh hosts_yml  generate -e @../BACKUP_DIR/hosts.yml
```
After executing ./install.sh hosts_yml generate, in hosts.yml, specify the correct value for keycloak_lb_hostname.
```
$ ./install.sh config_yml generate -e @../BACKUP_DIR/config.yml
$ ./install.sh ports_yml  generate -e @../BACKUP_DIR/ports.yml
$ test -f ../BACKUP_DIR/rpa.yml && cp -f ../BACKUP_DIR/rpa.yml rpa.yml || ./install.sh rpa_yml generate
```
note

If you want to use optional servers (for example, OCR on the 6-servers environment and CT, BEP Master, OCR for 8-servers or HA environment) as AGENT servers, add these servers to hosts.yml as agent_hostnames.

note

The new mssql_keycloak_user has been introduced with the default password in config.yml. Change it to the password of mssql_keycloak_user, which you have created on the 'prepare the database' step.
Encrypt config.yml:
```
$ ./install.sh encrypt config
```
In 10.2 version, the server.crt certificate must mandatorily include the end certificate and all intermediate ones if they exist. If your certificates do not comply with the requirements, prepare new ones according to the requirements.
Generate required internal certificates:
```
$ ./install.sh certs generate
```

If you upgrade in the multi-point way

On the MASTER server, generate configuration files as described above.
Ensure that PACKAGE_DIR, including installer package, certificates folder, config.yml, rpa.yml, ports.yml, and hosts.yml, are synchronized across all Linux hosts.

Check users' passwords

Ensure that users' passwords are valid in config.yml. In most cases, you don't need to change anything in the file. You may proceed further and skip this step. If you encounter issues, for example, an error message with invalid credentials, then:

Open config.yml for editing.

./install.sh edit_config master
# you'll be prompted for the decryption password

Update it with valid passwords.

nexus_admin_pass

mssql_dba_pass
mssql_ct_pass
mssql_ws_pass
mssql_sqc_pass
mssql_rpa_pass
mssql_pm_pass
mssql_dm_pass
mssql_ocr_pass
mssql_automl_mms_pass
mssql_keycloak_pass

Re-run the installation script.

For example, after the initial 10.1.4 installation, you may change the Nexus or MSSQL passwords manually in the environment. In this case, actualize them in config.yml because the installer will use them during the execution for updating DB schemas and Nexus artifacts).

Upgrade components on servers

Upgrade the components, depending on your installation approach:

Single-point non-HA and HA

Multi-point install

Multi-point HA

Remember to run the following command on the MASTER server as WFUSER.

Run the following command to set up the application user.

$ export ANSIBLE_PRIVATE_KEY_FILE="<path_to_ssh_key>"   # Path to SSH key for connection to all Linux servers as WFUSER.
$ export ANSIBLE_VAULT_PASS="<ansible_vault_password>"   # Password for decryption of config.yml.

Run the following command to remove outdated components of the previous installation:
```
$ cd PACKAGE_DIR
$ ./install.sh cleanup rudiments
```

Run the following commands:

$ ./install.sh precheck mssql   # Checks that MSSQL credentials are set correctly in config.yml, Database exists, wf_dba_user exists and has db_owner role
$ ./install.sh configure mssql  # Creates all required schemas in Workfusion DB, creates and maps DB users to provided MSSQL logins, and assigns correct user permissions per schemas

Run the upgrade commands:

$ ./install.sh preinstall full -e skip_bi=true -e skip_rpa=true -e skip_ocrwin=true
$ ./install.sh install full -e skip_bi=true -e skip_rpa=true -e skip_ocrwin=true
$ ./install.sh check full -e skip_bi=true -e skip_rpa=true -e skip_ocrwin=true

Before updating the RPA server, uninstall current RPA and perform a clean installation of new RPA:
```
$ ./install.sh uninstall rpa
$ ./install.sh install rpa
$ ./install.sh check rpa
```

Cleanup RabbitMQ queues:

On the server with the installation packages, run the command:
```
$ ./install.sh stop_services full # stop all services
```

On the server with rabbitmq (first MASTER server in the HA mode, or the MASTER server), run the commands:

$ wfmanager start rabbitmq
$ rabbitmq-diagnostics ping -q # repeat untill Ping succeeded (echo $? == 0)
$ rabbitmqctl --silent list_queues --vhost bep | awk '{ print $1 }' | xargs -r -L1 rabbitmqctl delete_queue --vhost bep

On the server with the installation package, run the command:
```
$ ./install.sh start_services full # start all services
```

The upgrade is complete. It may require Control Tower for about 5 minutes to start. So, if you see error 503 in a browser right now, wait a bit.

Run the following commands on each Linux server, as WFUSER:

On each Linux server, stop all IA Cloud services:
```
$ wfmanager stop all
```
To verify the status of services, use the command wfmanager status.
On each Linux servers, in the PACKAGE_DIR, run the following command to remove outdated components of the previous installation:
```
$ ./install.sh cleanup rudiments -c local --limit=<current_server_dns_name>
```

Run the following commands once on any Linux server:

$ ./install.sh precheck mssql   # Checks that MSSQL credentials are set correctly in config.yml, Database exists, wf_dba_user exists and has db_owner role
$ ./install.sh configure mssql  # Creates all required schemas in Workfusion DB, creates and maps DB users to provided MSSQL logins, and assigns correct user permissions per schemas

Install IA Cloud Enterprise components on all Linux servers by following the corresponding guide.

Note the server changes:
- For 6-server environment: your current APP server means MASTER, and BEP AGENT servers mean AGENT.
- For 8-server environment: your current INT server means MASTER, and BEP AGENT servers mean AGENT.
Log in to the RPA server and uninstall RPA components: Control Panel → Programs and Features → RPA (Uninstall).
Install RPA by following the instructions in the section Install RPA package.

Cleanup the RabbitMQ queues to ensure that old workers do not spawn queues:

$ wfmanager stop all        # Run on each Linux server
$ wfmanager start rabbitmq  # Run on all MASTER servers
$ rabbitmqctl --silent list_queues --vhost bep | awk '{ print $1 }' | xargs -r -L1 rabbitmqctl delete_queue --vhost bep      # Run on first MASTER server
$ wfmanager start all      # Run on each Linux server

Before starting installation, ensure that config.yml, ports.yml, rpa.yml, hosts.yml and the /certificates directory are the same on all hosts.

To upgrade components, run the following command on the server with the installation package as WFUSER:

On all Linux servers, prepare the environment variables:

$ export ANSIBLE_VAULT_PASS="<ansible_vault_password>"  # Run on each Linux server to disable password prompt (not mandatory, just for convenience)

On all Linux servers, enter the PACKAGE_DIR directory and run the following command to remove outdated components of the previous installation:
```
$ cd /opt/workfusion/wf_installer
$ ./install.sh cleanup rudiments -c local
```

Run the following commands once on any MASTER server:

$ ./install.sh precheck mssql   # Checks that MSSQL credentials are set correctly in config.yml, Database exists, wf_dba_user exists and has db_owner role
$ ./install.sh configure mssql  # Creates all required schemas in Workfusion DB, creates and maps DB users to provided MSSQL logins, and assigns correct user permissions per schemas

Install the IA Cloud Enterprise components on all Linux servers by following the corresponding guide.

Note the server changes:
- For 6-server environment: your current APP server means MASTER, and BEP AGENT servers mean AGENT.
- For 8-server environment: your current INT server means MASTER, and BEP AGENT servers mean AGENT.
After installing the Linux components, log in to the RPA server and uninstall RPA components: Control Panel → Programs and Features → RPA (Uninstall).
Install RPA by following the instructions in the section Install RPA package.

Clean up the RabbitMQ queues to ensure that old workers do not spawn queues:

$ wfmanager stop all        # Run on each Linux server
$ wfmanager start rabbitmq  # Run on all MASTER servers
$ rabbitmqctl --silent list_queues --vhost bep | awk '{ print $1 }' | xargs -r -L1 rabbitmqctl delete_queue --vhost bep # Run on first MASTER server
$ wfmanager start all      # Run on each Linux server

Upgrade Analytics server

Backup site configuration

Before upgrading the Analytics components, connect to the BI server via RDP as a Windows Administrator user and save all your custom workbooks and datasources to a predefined location on a local disk.

note

Download custom workbooks and datasources to separate directories. For example, c:\patch_10_2_backup\workbooks\ and c:\patch_10_2_backup\datasources\.

Don't save backup files in Analytics (BI) server installation directory for example, c:\workfusion\ as it will be deleted during upgrade.

To download the custom workbooks from the Analytics server UI:

Go to a particular site, and, on the Content tab, click Workbooks. To indentify custom workbooks, look for the _custom postfix in their names.
In the right corner of the Name column, click More (...), click Download, and save the file as a Tableau workbook.

To download the custom datasources from the Analytics server UI:

Go to a particular site, and, on the Content tab, click Datasources.
In the right corner of the Name column, click More (...), click Download, and save the file as a Tableau datasource.
Remember to rename the custom dashboards by replacing the all occurrences of the underscore character ("_") with a plus symbol ("+") in the titles, except for the first and last two underscores.
To restore custom dashboards follow the instructions in the section Backup and restore custom Analytics dashboards.

Upgrade Analytics

For single-point upgrade

For multi-point upgrade

To upgrade the Analytics Server:

On the MASTER server, run the following command:

$ cd /opt/workfusion/wf_installer
$ ./install.sh uninstall bi

Restart the Analytics server to apply changes.

On the MASTER server, run the following command:

Restore custom parameters from previous versions

note

When upgrading to v.10.2, you need to configure LDAP/AD and IDP/SSO manually in Keycloak.

For LDAP/AD configuration instructions, refer to the Configure LDAP section.
For IDP/SSO configuration instructions, refer to the Configure Identity Providers section.

Custom workers

If you have changed workers' settings in IA Cloud 10.1.4, you can migrate them after the upgrade.

For that, after upgrading to IA Cloud 10.2, on the MASTER server, open the file with workers' settings for Control Tower (for example, /opt/workfusion/vds-data/workers/app/com.workfusion.spa.ct/worker-app/10.1.0.32/worker.yml), and enter the previous corresponding settings, such as memory, CPU, etc. Note that the structure of the new file differs from the previous one.
