I have a vCenter server that is hosed. I cannot get the service to start, and if I do get it to start, I cannot connect to it via the thick or web client. So I am considering setting up a VCSA server in replacement to my windows based vCenter physical server. Now I cannot get on my existing vCenter installation to remove these hosts from their current clusters. Am I going to have any issues pulling these production hosts into a new vCenter server?
No problems at all...
Just deploy the new vCenter Server Appliance (vCSA) and add the extant vSphere hosts. They will lose their association with the old vCenter and join the new vCenter.
You will need to reestablish your cluster settings, rules and resource pools, but that's not complicated.
