User Migration from 2003 AD to 2008 AD with different domain names and no trusts
Posted on 2011-03-04
Have a best practices / how to question for you all. Here's the situation. I administer two domains of two sister companies in two different physical locations. Prior to today there was no need to have the domains "talk" to each other. So everything has been kept completely separate. Two different domains, two different domain names, etc. The companies are now merging, and at the end of April will be co-locating. Company A is moving into same building as Company B. This is a great move for both companies as we can better allocate resources and consolidate servers etc. But that is not the point. Company A has about 25 users, so a small domain. Company B is about 40 users so another small domain. The plan is to completely move all user accounts from Company A onto Company B's domain server, including all shared folders etc. My main concern is: what is the best way to preserve as much of Company A's user profiles, windows settings etc. Currently Company A has a GPO to redirect My Documents onto a network location for all users. Company A is also on a 2003 Enterprise domain, where Company B is on 2008 R2 Domain. Both Company A and Company B are 100% on Windows 7 Pro 64 Bit. I was planning doing this manually with each user utilizing Windows Easy Transfer tool, but having only Fri, Sat and Sunday to achieve this and to physically move Company A's office I'm worried about not having enough time. There are two IT people myself and my Helpdesk techy. Lets please have a discussion on best practices and how to achieve this goal the simplest and least risky way.
