I have vCenter 5.0 with mixed hosts, most of them are ESX 4.0, couple of them are ESXi 5.0. I would like upgrade vCenter to 5.1.
What is the best and least disruptive way to do so? I'm considering an in-place upgrade vs. building a new vcenter 5.1 and then migrating all the hosts into
that vCenter. What is the best and least disruptive way to do so? Are they both considered valid ways to achieve the same goal?
Thank you,
