Updating VM ESXi 4.1 to 5.*
Has anyone got any experience of updating VM from 4.1 to 5.5? Am I kidding myself by thinking it is as simple as booting each ESXi host to the update CD and running the update? Does the vCenter server need to be updated first and is that just a running setup from the CD and upgrading?
I am licensed for vSphere 5 Essentials Plus and vCenter Server 5 Essentials
I will be updating to server 2012 soon and would like to get the VM update done sharpish so I can concentrate on the 2012 stuff.
