One of my clients is using Active Directory with 18 different groups that FM authenticates against.
They just told me that they are changing their AD structure, moving to a new AD system.
I've never had a client move AD systems before. They said that all of the users will NOT be transferred at once - they'll probably do it a group at a time. From what I've gleaned from their email - for a period of time there will be two AD systems in place.
Any suggestions on the process that they should follow in order to make this go smoothly?
