Network with two Windows Server 2008 R2 domain controllers and Exchange 2007.  Here is the problem:

There are three servers that handle exchange: one for the information store, one for edge, one for owa.  All three servers have been shut down for a week.  
NOTE:  THESE SERVERS ARE NOT BEING USED.  THE COMPANY MOVED TO OFFICE 365 MONTHS AGO AND JUST NEVER GOT AROUND TO REMOVING THEM.

In the past three days, while the servers were shut down, one of the 2008 R2 DC's crashed and needs to be manually removed.  After that, a 2012 R2 DC was added to the domain.  

Question:  Is it acceptable to turn the three Exchange servers back on and gracefully uninstall exchange with all the AD changes made after the install of a 2012 R2 DC (the forest functional level was moved from 2000 to 2008, also) or do we have to crank up ADSI Edit and manually remove Exchange from the domain?  

Before anyone says anything, I'm not the guy who did all this.  I'm the consultant hired to clean it up.  :)
