One of the last steps to conclude the migration process is to remove the Routing Group Connectors.
From there, it is absolutely essential that Exchange 2003 be uninstalled from the SBS 2003 server!
Make sure to have disk 2 handy for the Exchange uninstall as the files in the Exchsrvr65 folder will be requested during the process.
From there we DCPromo the old SBS 2003 box to remove Active Directory.
The SBS server we are working on has not had all of the redirected folders moved over to the new SBS 2008 box yet. So, we will leave it alone as a member server until early next week when we will Workgroup it and then clean up SBS 2008’s DNS, Active Directory, and remove any legacy settings where required.
