migrate users to new domain

I have two locations and two domains.  Location A which is our main location and Location B which is a secondary location.  At these locations they are set up so that location A is Local.mycompany.com and location B is abccompany.com.  They are two totally different domains, not even in the same forest.  I am running a Windows 2003 domain on each side and have trusts set up because each location actually connects to and utilizes serves at each location.  I am looking for the best configuration.  I would like suggestions from users.  Location A has around 10 servers and 100 + workstations and location B has 4 server with about 25 workstations.  Mailserver is located at Location A and users currently login to that doamin and has a user id in order that send and receive email.  I am think of just moving everyone to one domain, the one in Location A.  It seems much simpiler.  

I also have a Windows 2008 server at each location but neither are domain controllers just yet.

Any suggestions are welcome.

Agree with ve3ofa. ADMT can help you migrate user profiles.

A good start is check out the whole lifecycle "Checklist: Performing an Interforest Migration"

Specifically for the Managing Users, Groups, and User Profiles section

There is a doc on Active Directory Migration Tool (ADMT) Guide: Migrating and Restructuring Active Directory Domains @ http://www.microsoft.com/download/en/details.aspx?id=19188

A quick list in this useful sharing - Migrate users to a new AD forest

Commerical tool - ForensiT (more than just Windows...)

Lastly if you are thinking of PC hardware refresh scenario, you can check out USMT scenarios to understand more. Rather limited

I think I need to back up on my question.  I need advice on how to get to this point with the least amount of down time.  Should I add a second site in AD sites and services at Location A and then add a server in that new site at Location B.  Then migrate my users over to that server?  Can I do that while my other Domain exists at Location B?  This is the part I need suggestions on first.  Sorry I was not more clear.
