I have read over alot of migration white papers and have a few questions on some of the details. Background: I have a client with 75 users on an SBS 2003 box. 90% are POP accounts on exchange. The way I see it I have two choices: Start all over and create a new domain and do profile changes and domain switch etc to the office (10%) and just recreate all the user accounts and passwords for the POP users (90%) or migrate the Active Directory and domain etc from SBS. pros and cons anyone? I hate moving profiles and synced folders on laptops etc to a new domain not to mention recreating 75 user accounts. My fear is that in moving over the AD it will still have the 75 user limitation or other SBS related limits. anyone put these fears to reat or have done a similar migration?
