Hello all,
In the vSphere 5.1 release notes, it states: "vCenter Server 5.1 can manage ESXi 5.x hosts in the same cluster with ESX/ESXi 4.x hosts."
We have already upgraded vCenter/Update Manager from 4.1 U2 to 5.1, and are now going to work on the ESX hosts. The plan is to take a host out of the cluster, re-install it from scratch with ESXi 5.1, and then put it back in the cluster. There's a dozen ESX 4.1 hosts in our current HA/DRS cluster. We'll do one at a time and in a week or so should be all at 5.1.
I was wondering if anyone has run into any issues or has any comments on having both ESX 4.1 and ESXi 5.1 in the same cluster.
Thanks for your help...
