Just recently acquired a new company with 20 standalone computers (desktops and laptops, Windows 7 and 8.1), that are part of a WORKGROUP, with no local server at all. This site will be getting a network upgrade, and will soon have a VPN tunnel to the Main Office (but not until cutover weekend, a month and a half in the future). Now, all these computers have local user accounts, and some are shared computers, so copying data to a centralized location is going to be bothersome (especially if people keep modifying/creating data everyday). Not sure what to do...
Would anyone advise on what to do in this case? I'd like to minimize downtime for these users while migrating them to our domain.
