I understand that NT4 CALs are not usable for Win2k, but are the Win2k CALS usable by Win2k3?

That is correct. WIndows 2000 cals are backwards compatable for Windows NT 4.0. This also works for Exchange 2000 can be used for Exchange 5.5. This also can be applied to SQL.

OK, now if an upgrade to Win2003 is done, and NT is taken out of the picture, will it be necessary to obtain CALs. I would think so, but not sure. We'd still have the NT licenses, are these upgradeable or new become necessary?
