Exchange 2003/2010 cross-forest migration

[unclerico]

I am in the beginning stages of planning an inter-forest AD migration as well as Exchange 2003 to 2010 migration for a company we recently purchased. I found the following technet blog post that does a pretty good job of explaining the steps that need to be taken in order to make the migration go smoothly(

I guess I would just like to know from anyone on here that has actually carried out the process if there are any gotchas? It looks like I need to make sure I carry out the mailbox migration first and then use ADMT to do the user migration. Besides this, is there anything else you've come across?? Thanks in advance.

There is generally far more to worry about in terms of the ADMT migration. There are PLENTY of things that get into the way of migrating servers and workstations, including firewalls (hardware and software), services not starting, DNS issues, rights, etc. Many of the things can be rectified with migration specific GPO settings.

Thanks Pat. I think I've got the ADMT down since it doesn't look like much has changed from when I last did a 2003 to 2003 inter-forest migration. The Exchange portion, however, is another story.

There are scripts "*.ps1" to help you in your cause for Preparing-MoveRequests. Also, after EK10SP1 you can do ADMT first and then the MoveRequests if so desired.
