Removing an Domain Controler Role from Exchange 2010 server
Hello Experts,
I have recently taken over a network and I am looking to raise the functional domain level from 2008 -> 2012.
In a previous admin's wisdom he/she has installed the domain controller role on an exchange 2010 server that has the MAILBOX, CLIENT_ACCESS, HUB_TRANSPORT role installed.
The FSMO rule is on 'DC-01' and other DC's are available EG 'DC-02', DC-03 etc..
About this server 'EX-01'
Exchange 2010 sp3
Windows server 2008
My question 'Can I remove the Domain Controller Role from this server (and get away with it) and have no lasting impact on exchange 2010?' - Will I break my setup?

It's foolish in my opinion to put your server in an unsupported state:

Adding/Removing the DC-Role while Exchange is installed, is not supported so forget about your Option 2.

Hi Lee,
totally agree that's why I moved all my mailboxes off on to a new Exchange server, took the DC role off it then decommissioned the old server.
Just because you can do it does not mean you should!
Many Thanks

Running DC promo to demote a DC with Exchange on it makes a lot of changes to DNS that break that server's ability to advertise itself as an Exchange server. It won't irreparably break Exchange, but it will break it pretty good. And you'll never be able to get help from Microsoft with that server again (This is more of a secondary issue considering how most of my interactions with MS support have gone).

Thanks guys. Just wanted clarification on this issue.
It's a big risk to the business since this is a physical server.
If this was in a virtual environment, I might have risked it. (but even then I would imagine there could still be issues.)
I have decided just to build an exchange 2013 server and migrate to 'hybrid exchange'.
Less risk to the business and more functionality gained.
Just ruins a deadline for me. :)

I understand your reasoning for doing this but you may end up breaking more things in the long run..
You could stand up a second Exchange 2010 server and migration all MDX's to it then decommission the old one
