Hi all, I'm working through an upgrade of a 4.1 Enterprise Plus cluster to 5.1. Thus far, I've gotten vCenter updated to 5.1 build 947673 and I took one host out of the cluster, wiped it, and did a fresh install of ESXi 5.1, then patched up to current build 914609. I added it back in as a new host to vCenter. I updated a quantity of v4 cpu licenses to v5 and applied the new key. All licenses are enterprise plus.
I went to Home -> Inventory -> Networking and attempted to add the new host into one of the distributed virtual switches but it does not show in the list of available hosts, nor does it show in the list of incompatible hosts; both are empty. It's ports don't show up as available to add to a port group.
Any ideas? Can you not mix 4.1 and 5.1 hosts in a distributed switch? Hopefully that's not hte issue or that will make upgrading difficult.
Thanks!
