We have a 2010 farm and are in the process of creating a new 2013 farm in a new Active Directory domain. We want to migrate all content/users to the new domain. All users are currently setup to use Domain\000001 numbers. We are also changing this to Domain\N000001. Are there any tools either OOB or 3rd party that will help us migrated all users. There are 20,000+ users so manually will not work.
Thanks
