Only one question I can answer. You will definitely need separate KMS hosts for Vista and 2008.
That's another one of these MS docs that isn't clear but you can't have more than one KMS key on a single host, or at when we tried to add our vista KMS key to a server 08 kms host, it gave an error that the key was invalid.

If so, can you please share experiences good/bad? I realize clean installs are always the best, but we are looking at this for some of our servers that are already running WS03 x64 and could be a pain to do a clean installation, if it's really not needed. We've done a lot of upgrades with past server versions going back to NT, and of course will have alternate plans in case things does not go well. What I'm finding out there so far on upgrades from '03 to '08 is kind of "icky", for lack of a better word. For example, this Technet article: Known Issues When Upgrading to Windows Server 2008 http://technet.microsoft.com/en-us/library/cc731003.aspx Makes it sound like you can't upgrade a server that has more than just a C drive installed. Or do they really just mean that your C drive must be on drive 0? For example, if I'm upgrading a DC with AD logs sitting on the D drive, removing hard drives half way through the installation will not be an option-I would need to take the time to move the logs ahead of time to the C drive for the upgrade. How about the whole printer backup/restore thing? Does that mean the printers will migrate (if you run the procedure) or they won't? If they migrate, I'm assuming I still need to have all third-party drivers downloaded and ready when '08 asks for them? And, would I need to then also reinstall XP-style drivers for the XP and 2003 server machines to download? I'm trying to figure out if it wouldn't be best to leave our print servers on '03 while the majority of the clients are still XP. We are licensed under MS Schools for '08, so it's not a cost issue at this point. Also, for anyone using KMS licensing for WS08 server-can it live on the same server as a Vista KMS, or does it need to be separate? Just trying to do as much reading and get all the ducks in a row before I run a test on one. Obviously I'll be updating server firmware and have new WS08 drivers handy.
