Any exchange 2010 schema related task need to be done before or after Domain controller upgrade to 2012 R2?

At our company, we plan on migrating domain controllers from 2008 R2 to 2012 R2. We currently are running exchange 2010 (eventually moving to 2013 sometime next year). Do we have to run any exchange related "schema" items before or after we run domain and forest prep on the 2012 DC servers? I just dont want exchange to break when this happens.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

No your schema version will already be at the correct level for Exchange 2010, when you start upgrading to 2013 you will need to.
