We have a new client that we have recently started providing IT solutions too and currently have a situation where the client is not willing to upgrade their server hardware and instead wish to only upgrade the operating system from Windows 2000 SBS to Windows 2003 SBS. They currently running a 2000 SBS DC with a Windows 2003 Terminal Server. I have only ever fresh installed Windows 2003 SBS for initial setup and disaster recovery where I had to re-create users and recover the Exchange 2003 DB, user folder etc. So I have a couple of questions that I require definitive answers too:
1.) What is involved in upgrading from Windows 2000 SBS to 2003 SBS on the same box. Any documentation for this procedure or do I just ensure the server is backed up, unplug LAN, insert the 2003 SBS CD and start upgrade? Any particular service pack levels required to perform this upgrade?
2.) Other issues I can think of include upgrade ability of existing application ie: Should I remove all non-Microsoft Apps from the server before the OS upgrade?
3.) In terms of licensing; will I need to buy all new CALs for Windows 2003 SBS as well as Windows 2003 SBS?
4.) Is it possible to change the local domain name in this procedure?
5.) They are currently using ISA Server 2000 which we no longer wish to utilize, what will happen to this during the upgrade to 2003 SBS?
6.) Will there be any changes to be made to the Windows 2003 Terminal Server to work with the upgraded 2000 SBS box? I'm assuming that by upgrading I can't change the local domain hence retaining all Security IDs therefore allowing the 2003 Server to maintain it's membership to the upgraded domain controller.
7.) Wild Cards: Anything else anyone can think of that I have not covered in my previous questions.
