I have a cluster of three hosts running vSphere 4.0 with a 32bit vCenter 4.0 server. Its a fairly simple environment with a small number of resources groups and about 50 servers.
I want to move these three hosts into a new cluster of 4.1 hosts (two) with a 64bit vCenter.
The hosts are all the same servers with the same specs. It seems like the easiest thing to do would be to move my hosts in the 4.0 server and add them to the 4.1 server. It seems pretty straight forward. Is this a bad way to go about this? Will there be problems when I connect the 4.0 hosts to the 4.1 cluster?
If I migrate from one to the other, I need all of the extra space for the migration and I do not have it. This seems like the simplest easiest way to keep everything in place.
