I'm about to set off on a new project to update our esx nodes.... but first id like to get our VirtualCenter server up to U4.. Are there any "minimum" host patch level requirements piror to U4 on VirtualCenter?
Or any issues you guys have had with different rev/patch levels that i should be aware of during this process? Not a massive update, but i have around 25 hosts or so to get done.....
Thanks

vCenter 2.5.x can manage 3.0.x hosts all the way to 3.5.0U4 hosts, so there is no specific patch level you must to be at on your ESX Hosts.
for your vCenter upgrade to U4, it's pretty straight forward and the same principles apply as any other update. There is a schema upgrade on your DB, so you should get a full backup before you start.
If you are going from 2.0.x just note this KB
Also, if you are going to be installing the performance overview plugin, just be aware of a couple of KBs
Installing the Performance Overview Plug-In in VirtualCenter 2.5 Update 4
vCenter 2.5.x can manage 3.0.x hosts all the way to 3.5.0U4 hosts, so there is no specific patch level you must to be at on your ESX Hosts.

I've always updated VC first.. then the nodes... I've seen issues where the esx nodes were at U4 and the VC server (2.5 say U1) caused issues...
I agree, your vCenter instance should always be at or higher than your ESX builds.
