I am about to begin an exchange migration from a Windows 2000 sp4/exchange 2003 server onto a new Windows 2003 server which will also run Exchange 2003.
My query is in relation to SP levels. The current old Exchange server doesnt have any Exchange SP's. Should/do I need to upgrade it to Exchange 2003 SP2 before I do the migration?
Also, if I need to do this do have to install the rollup for windows 2000 sp4 before I do the exchange SP? The reason i am asking is i am reluctent to do the rollup for windows 2000 unless I have to as I have seen and read about it causing issues before.
