How to update the Build Agent Manually in Azure DevOps 2020?

Question

We have recently upgraded to Azure DevOps 2020 on our testing environment, previously we had TFS 2017 and then upgraded Azure DevOps 2019 and now to Azure DevOps 2020.

I am facing issue regarding the agents I had configured in the earlier version. They don't see to update when I click on the update agent link.

I have one agent i.e. POC_2017Agent installed and created with TFS 2017 agent and the last two agents were created and installed with Azure DevOps 2019. After we upgraded to 2020 all 3 of them are shown as Offline, even when their services on the servers are running\restarted.

How can I upgrade the agents manually, if they are not getting upgraded automatically after clicking on the update Agent link?

I don't want to remove them and reconfigure again.

Please check the agent log which locates in the _diag folder where the agent was installed. The log is supposed giving more information. You can mask the private information and share the log. – Legislative

Beginning with Azure DevOps Server 2019, you can configure your server to look for the agent package files on a local disk. This configuration will override the default version that came with the server at the time of its release.
