Hi bparlier,
First of all, thanks for the info; you confirmed a lot of things for me. I still have a couple questions though.
1 - Looks like I will install a new VCenter server. Relating to "schema changes to the DB, new requirements (i.e. SSO) for vSphere" I'm not sure what you mean. Is this only if I go the upgrade path? Relating to this, can I simply uninstall VirtualCenter, install VCenter, and import the old hosts (and obviously the new hosts when they are installed)? Is there anything that I need to be concerned about while these hosts are not connected to VirtualCenter? I'm assuming there will be no VMotion support until this is done but is there anything else?
2 - I kind of figured I would have to do that. Is there a guide to safely un-registering machines and re-registering them on new hosts?
3 - What compatibility guide are you referring to?
4 - Same as 3.
