Didn't think there would be, just going over different methods in my head.
This was my plan, problem is people want instant results from the word go. So a gradual transition is the best for this I feel. Waiting until summer just isn't an option at this stage unfortunately. I was going to move the home folders, recreate the users on the new domain and take it from there. Don't have to worry about exchange, it's externally hosted.
Because I can't create a new domain and I'm going to have to image machines gradually during term time, are the OUs and WMI filters the best way to do it within the same domain? So that they can use both types of workstation from 1 set of credentials?
Also, there is a lot of legacy software that some subjects depend on to be able to teach, if I just cut RM out and then dealt with these after, I fear there would be a lot of lost learning time. Which also means that for some time at least, select people are going to need to be able to log on to both.
Think the powers that be want a noticeable difference straight away, but I know if they want that it's going to be gradual rather than done all at once over summer.
