I have a 4.1 environment that I want to upgrade before moving to 5.5. I have an existing 5.0 Update Patch Level 3 vCenter environment. I want to combine the 41. into the 5.0 and then upgrade. The hsots in the 4.1 environment are using standard vSwitches with no distributed. I was thinking that I would disconnect the hosts from vCenter 4.1 and then add them into thier own cluster in vCenter 5.0. At that point I could just upgrade the hosts to 5.0. Once all the host have been moved I would decom the 4.1 vCenter Server and then start plans for upgrading to 5.5.
Any thoughts or concerns?
If I disconnect the hosts that should turn off the vms right?
I know that 5.0 update 3 can manage the 4.1 esxi 702113 hosts from the interoperability matrix.
Suggestions?
