Hi Ben,
We've decided to do a full test build of the hardware then the software - setting up eight hosts and the new SAN. Then I'll do a stack of testing of vMotions/Storage vMotion etc of test servers form the old environment to the new just to test all the scenarios work (and test within the cluster as well). If there's any dramas, they'll only be test VMs and no real data of importance would be lost. Provided all the tests go well, I'll do a rebuild of the environment (thereby restarting the 60 day evaluation period again) and do a quicker test just to make sure it's the way it was set up first time round then go hell for leather and vMotion myself silly.
I've got six old hosts and eight new ones with a new SAN and around 100 VM's so I'm thinking 60 days should give me enough time to get the bulk moved in a week or two and have 40 or so days to resolve the 10% that are bound to cause some issues.
I'm assuming I just install the license key on the new hosts via vCenter as normal when I'm cut over and just shut off the old hosts?
Thanks.
