Cross Forest Moves in AD and exchange Mailbox moves

The setup is that i have 2 domain's in two forest's they both have a two way trust between them, everything was fine untill we decided to get rid of one of the domain's. My question is how to I move User's from on DC to another DC, these are standalone DC's, as there was trust before the user's could authenticate without any problem. I have an exchange server in that domain that i would need to move as well once i move the user's.
Any help would be appreciated.

Hi SystmProg,
Thanks for the reply, but the article states this is a single forest as in my scenario these are two different forest's. These are two seperate machines in two separete remote locations. One is abc.local and the second one is xyz.local
They are in different domain's and different forest's. They do not fall under a single forest.
Now the question is since my company wants to get rid of ABC.local machine this is a primary domain controller as well, how do i move the user's over to the new forest and new domain which is xyz.local

You will need to initiate a move proccess against DC's in both forests that hold the the RID master roles.

when i read this it meant movetree.exe was used for intra forest transfer's, according to microsoft documentation it states that clonepr.vbs is used to do interforest transfer's any idea?

Used to clone user and group accounts from a Microsoft Windows NT 4.0 source domain or a Microsoft Windows 2000 source domain in a separate forest to a native mode Windows 2000 target domain. (Command Line Tool)

Alternatively you can use ADMT (Active Directory Migration Tool). Migration cookbook is available from Microsoft, which describes all the tools available:

arite here is the update ADMT works fine. Now for the exchange mailboxes.
Since its a new organization how should the mailboxes be moved to the new exchange server.
These are exchange 2003 with SP1

Sorry about this the question was abondoned but i figured out what the difference is. The capability of doing a cross forest move for a mailbox is available only in Exchange 2003 SP1 if running anything lower then that you can do an intra forest mailbox move.
Basically the question started with Inter-forest migration's rather then intra-forest migrations. It was a brand new tree, new forest and a new domain.
I don't remember the articles that i went thru but the final solution was to bring both the exchange server's upto SP1. Create a 2 way transit trust between both forests. Add an admin ID from each domain as an exchange admin on the opposite forest basically cross certification. Once that was done then i moved mailboxes across and it worked fine.
The user's have been up and running no complaints till now. But every one thanks for your help.

Since DeltaFire did mention about ADMT it was a good idea to do that in that environment, I didn't use it because there were not that many mailboxes and the new Exchange 2003 SP1 gives you that functionality as well. I don't know how to give him partial points, if someone could please guide me that would be great.
