Windows Server 2008 Migration
We are going to starting the process of upgrading our server OS soon from Server 2008 to 2012 R2.
We have 3 servers running 2008, one is the PDC, another is file and SQL server and last one is Exchange 2010.
I know the adprep needs to be run on the PDC, do I run this on the Exchange server as well? If so, is there anything I need to look at for or any special attention that needs to be directed at the Exchange?
How have your experiences been with the migration?

Only have File Services and IIS rolls installed on the Exchange.
As much as I would love to go virtual my bosses at this point don't like the idea of not seeing physical servers, bit old school it would seem.
But my approach would be the same, I plan on creating a VM then have the roles moved to that, the current server hardware is still fine and will be reused, maybe add some RAM and other drives.
So basically create a VM, transfer the roles, have the two run parallel just in case of issues, if the migration goes well the 2008 will be retired and the hardware will be reinstalled with 2012 R2, then transfer the roles the hardware.

Sounds good, although configuring Exchange on a VM just to re-install back on the physical hardware doesn't sound too fun!
You could try a P to V conversion so you move your existing Exchange/File Server/IIS to VM's to free up the hardware? I wouldn't suggest PtoV of a DC though but DC migration's are much more straightforward

The Exchange will come at a later stage as we would be moving to 2013, for now it's just the DC. Not having additional hardware makes this whole process a pain, but it has to get done.

Just so I know I'm on the right path, I have installed 2012 R2, it's been fully updated.
Static IP has been assigned.
Next, join to domain.
Run adprep on current DC.
Start transferring roles one at a time, allow couples of hours, even a day, for each role's testing.
This sound about right?

Thanks Tom, link is very useful
I've migrated 2008 to 2008R2, 2012 and 2012R2 on many different servers and roles by configuring the new VM and switching over
