# Upgrading to newer versions

Follow the instructions below for upgrading an existing agent:

# Windows

Open Workato and go to your on-prem group page (opens new window).
Open your on-prem group and find the agent that you want to upgrade. Check current agent version and click on Update to <latest_agent_version>.

Update on-prem agent to latest version

The upgrade wizard will open. Check the release notes and follow the steps in the wizard, which are also mentioned below.

On-prem agent upgrade wizard

Verify that the agent is stopped (either terminate Workato Agent Windows service or console-based agent)
Uninstall the agent (for example, Start Menu → Workato → Uninstall). This should not change the config.yml file and the certificate files (cert.key, cert.pem) in C:\Program Files\Workato Agent/conf.
Run the downloaded installer (this will automatically install to the same location)
Run the agent. Depending on the setup, either start Workato Agent Windows service or run the agent from command line.
Make sure your agent is active and verify its version number on the on-prem agent page (opens new window).

Verify that the agent process is stopped. The upgrade will fail if any running agents are detected.
Navigate to the agent directory (for example, cd ~/programs/workato-agent/). Do not navigate further into the /bin/ directory.
Run the upgrade script: bin/upgrade.sh. Make sure you have enough permissions.
Follow the instructions provided by the upgrade script. Confirm the upgrade when prompted.
Upon successful completion of the upgrade, run the agent (for example, bin/run.sh).
Make sure your agent is active and verify its version number on the on-prem agent page (opens new window).
The upgrade process is not triggered if no new versions are available. However, it might be necessary to repair a broken installation; in that case use the command line option when running the upgrade: bin/upgrade.sh --force.

For Linux/MacOS users, if you have anaconda installed on your terminal, be sure to deactivate any conda environments with conda deactivate as it will cause an error when upgrading.
On-prem agent versions 2.11.0 and newer are using latest Workato gateways. If you are upgrading from version older than 2.11.0 make sure that you whitelist the new gateway IPs.
