Two OpenNebula on the same vCenter cluster

is that possible?

i have an old 5.8.4 that i can’t seem to upgrade no matter what i do
so i thought of settings up a fresh 5.12 beside it, and manually redo all the settings. my question is, what will be the behavior? will it somehow “bother” the vms that they have 2 opennebula systems “watching” them?
