Factors to consider in a Cross AD forest migrations

Hi,

I am going to move from a windows 2008 mixed mode forest to a windows 2003 native mode one. Is there any factors that i should consider when doing the migration?

We have exchange 2010 running as well which needs to be migrated.

Is there anything that i need to be concerned about?

If you want to migrate user from one domain to new domain using ADMT tool you need to create trust relationship between two domain.

You need to understand nuances of ADMT and its working before you actually taken on migration production env.Also, its much better if you can simulate in a lab environment for successful result. I have below link which might help you to understand this. Start from reading ADMT guide first.

Done.
