Adding new hardware and Upgrading the Virtualized Environment
Posted on 2014-03-14
My current environment is running on VMWare vSphere 5.1, with one vCenter 5.1. I want to add a new vCenter 5.5 and connect to it the new ESXi 5.5 servers and the old ESXi 5.1 ones at the same time. So can I connect two vCenters with different versions to the same ESXi servers at the same time?
The new vCenter will be created to have the same SVs and data stores like the old one? Are there any complications?
Reason for doing that is to VMotion the VMs currently located on the old ESXi 5.1 servers to the new ESXi 5.5 servers with no downtime and after I move them I will upgrade the old ones to 5.5. Would that work? What are the proper steps?
Note: The old vCenter is physical and I am planning to have the new one as a VM on one of the new ESXi 5.5 servers.
