I made time to apply VMware VirtualCenter 2.5 Update 1 to my test environment. Worked great but it did require a reboot of the VC host at the end. Older VC clients seem to connect just fine to the newer server software, but I upgraded mine anyhow just out of habit.
Once that was done I used Update Manager to apply the ESX 3.5 Update 1 patches to my test ESX hosts. The process seems to be getting smoother, as it successfully moved through my test cluster and patched everything. Took a while but it was fire & forget.
Overall, looks good so far.
Where did you end up getting the VC2.5 update at? VMware’s website only shows up to VC2.01 for patches and a ticket is open at VMware for the webmasters to get it fixed…
Grab it from the normal download page:

The installer will do the upgrade, too.
