I should of added I am migrating from AD2003 to AD2008R2. From Exchange 2007 to 2007
Hi Darrengp,

I think the easiest option is to migrate the groups using ADMT. In the new environment, you can use powershell also to mail enable all the groups "enable-distributiongroup"
The contacts should migrate without a problem using ADMT.

I can't see how to migrate contacts using ADMT there is no option I can see. I am using 3.1 BTW
I have just done the groups and ADMT brought them over as DG :)
Yep you are doesn't do that :( , sorry for that "tip".
A former customer used MIIS for the coexistence between multiple forests and syncing the contacts between the organizations.
I don't know if it will work in your situation to do a single, one-time sync....
Maybe LDIFDE.exe also may be sufficient for you. I don't have much experience with this tool, check it out, maybe the windows tool is sufficient for contacts...

Sorry for the delay I ended up using Powershell to complete this
