We're currently running View 5.3.0 in our production environment. I'm testing the upgrade to View 6.1.1, and according to the compatibility matrix, a 6.1.1 connection server should work with agents running 5.3.0, at least for the upgrade period. However, if I recreate pools for the VMs on the 6.1.1 connection server without upgrading the agent on the VM, I just get "Error". Not "Agent Unreachable", just "Error". I'm definitely able to ping the connection server from the VM. I should also mention these are manual pools, if that makes a difference.
