Hi,
We are in the process for migrating from a Windows 2003 domain to a Windows 2008 one.  We are currectly running Exchange 2007 SP1 and wanted to see if there are any steps we need to take to ensure Exchange still functions during the migration.  Do we need to run schema prep or domain prep again so that the 2008 DC's are updated?  Is there anything else like that, that needs to be run again or updated?
Thanks.

There won't be any issues with your migration. Exchange 2007 will continue to work quite happily with 2008 R2 domain controllers.

>> Do we need to run schema prep or domain prep again so that the 2008 DC's are updated?

Not at all. When Exchange 2007 was first installed, the additions it required were added to the schema. There is a single schema partition for the whole of your Active Directory forest, so once the new DCs are added, the proper schema will be replicated to them along with your Configuration and domain directories which contain user/computer/group/GPO/Exchange/AD configuration data.

As part of your migration plan, you should already have documented the requirement to promote those 2008 R2 DCs to Global Catalog (GC) servers before removing the old DCs from the network. Do make sure this happens in good time so that they can build their GC data; Exchange, computer logons and other services will suffer if this step isn't completed.

For your peace of mind, the Exchange supportability matrix is here: http://technet.microsoft.com/en-us/library/ff728623.aspx. As you can see, Exchange 2007 SP1 is happily supported when used with 2008 R2 DCs on the network.
