I am in the process of upgrading my VMware vCenter Server from 5.5 to 6.0. This is my first attempt at upgrading a vCenter Server so I am flying a little blind here. When I begin to run the upgrade, I receive the following message:
"Warning: This vCenter Server has extensions registered that cannot be upgraded to or may not work with the new vCenter Server.
VMware vSphere Update Manager Extension on
Is this something that I need to be concerned with or is it normal when upgrading from 5.5 to 6.0?
