This is 1 of several questions we need to ask about migrating from Small Business Server 2003 to a standard Domain running 1 server with Server 2012 R2. So please limit your answer to this one specific question:
We have added the new member server, moved the Enterprise accounting and antivirus. Exchange E-mail has moved to the cloud. What is the best way to go from here? ...In stages? ...One big move? ...A link with details would be helpful.
Briefly, we do not use some of the SBS2003 subsystems like WSUS, SharePoint, Remote Desktop Services (RRAS), and DFS/FRS. But we do have user folders, shared folder with group permissions, and synchronized document folders.
