Good Morning, 

We have a customer who will be migrating their users from an old domain to a new one. We are looking for some directions or documentation on how to handle the transition so that users migrate over succesfully (not Delete/Recreate all users). We also need the AD groups at the repository level to migrate over. Finally, is it possible for these users to go from OLD AD Domain users to NEW AD Domain Users in Forms(Repository Authentication) without losing all history, or in-progress Forms? 

Thanks,
