We have to re-install a Unity server for one of our customers and have the following question. They're running Unity 4.2.1 in VM-only mode, using Win2K/Ex2K for OS/Mailstore. We have the Unity media for the re-install, but we are missing the platform configuration DVD's. We have our hands on Win2K3/Exc2k3 CD/DVD's. The question is can we do this install and have them loaded in a 2003 environment without any issues? They'll still be running Unity 4.2.1 and the same license file could be used. Does anybody see any issues with this? Also, it looks like the Exchange 2003 CD doesn't have any licnese key printed on its sleeve/cover, similar to how we've seen on the Exchange 2000 CD's. Any thoughts on that?
