I have an installation of a single Windows 2003 Server (Standard) that is out of disk space. It serves about 15 ysers. I'm upgrading the disk system, removing the existing SATA drives and replacing them with a Adaptec RAID Card and larger SATA drives configured for RAID 10. During this change out I'm looking to deploy Exchange 2003, so I'm seriously looking to move to SBS 2003. I'm planning on keeping the domain and server name the same. I doubt that I can migrate active directory to the new box, can this be done? Is there anyway that I can reuse the existing user profiles on the XP Pro client computers?
