Warning About Extensions When Upgrading from cVenter 5.5 to 6.0

csimmons1324 used Ask the Experts™
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?

Yes this is normal, and should not cause you concern, it's just a warning to remind you.

Don't forget to install Update Manager if required.
