We have our TeamCity server and Build Agents installed on separate remote machines. We are now going to move the projects from this server to a new TeamCity server, but the Build Agents will remain the same and will need to connect to the new server.
But the current TC server's version is 9.0, and the new server's version is 9.1.5. Do we need to upgrade the Build Agents as well, or will the same build agents be able to work with the new server without any issue? If an upgrade is essential, which Build Agent version is compatible with TC server version 9.1.4 or 9.1.5?
