Upgrade v4.1 Linked-Mode to v5.0

[WGSSS]

Hey,

I have four vCenters in linked-mode, all on 4.1 Update 1. I've checked the v5 documentation but can't find anything about upgrading vCenters that are already in linked-mode configuration. Is there anything I should be aware of, or can I just hit them one at a time to get them all up to v5?

Cheers,

Graeme

you cannot link a vSphere4 and vSphere5 vCenter instance.  You'll need to break you're linked mode configuration, then upgrade the hosts as standalone. From there you can modify the install and link them all together once they are vCenter 5
