I have a mix of W2K3 SP1 and SP2 servers in my domain and need to upgrade them all to R2. Of these, most are DCs and also run Exchange Server, with some also running SQL (2000 or 2005)
Think the SP1 upgrade to R2 is just like installing a service update but am I likely to have problems updating the SP2 machines? I get a message saying you are installing an older version of the operating system when I run the update against an SP2 machine and worried something may break.
Thanks
