rocketmouse -> Major dilemna with upgrade / migration from Exch 07 to 2010 (21.Jan.2017 8:50:07 AM)

So, I have a dilemma.

Client was running SBS2003 (demoted), Server2008 std (Is a DC) with Exchange 2007 sp3.
Am in the process of upgrading / migrating to server 2008 r2 and Exchange
2010. 2008 r2 server has all fsmo roles (Is Master of all) but when I
go to install Ex2010, it fails because domain/forest functionality stuck
at server 2008 std (Not r2). Is it possible to do an OS in place upgrade
from std to r2 on the exchange 2007 box in order to completely raise the
domain functionality to 2008 r2? Will exchange 2007 break if I manually
change functionality with adsiedit?

Other options?
