Hello
I would like to upgrade vCenter Server from 4.1 to Version 5 soon. vCenter is now installed on a x64-W2K3 Server and I want to replace this server with a new hardware and W2K8R2.
So I read the Upgrade Guide and KB1031307. I want to use the same DB and upgrade it.
There is one point that I don't understand: The vCenter Host Agent Pre-Upgrade Checker checks for issues concerning the agent software on the ESX hosts.It checks, if the agent software can be upgraded etc.
In KB 12031307 it is written that when upgrading on the same machine, I have to run the Upgrade checker utility.
Under the point upgrading to vCenter Server on a Different Machine and Upgrade the Existing Database nothing is said about running the upgrade checker utility or not!
Do I have to run it in this scenario or isn't it necessary? In my understanding, the host software on the ESX servers is upgraded the same way, regardless if I do an upgrade on the same server or on a different machine.... so I assume I have to run it on the old server before doing the upgrade on the new machine?
thank you for any help/explanation
best regards,
Roland
