Hi,

I've a couple of 2012 DC's I want to upgrade to 2012 R2. Two of the DC's are also running DHCP.

Would it cause any problems if I upgrade them to 2012 R2?

I haven't done this in our production but I haven't heard of any issues from 2012 to R2.  A lot of folks will tell you to build out the news DCs fresh but in this case of just going to R2 you shouldn't run into issues.

Test in the lab first just to get a feel for it.

Thanks

If you feel the need to test it then by all means do, however the R2 upgrade won't affect your DC if all you have is DHCP running off of it.  What I would do though obviously, is create a backup of your DC (always a good idea), and take a backup of DHCP in case you need to import settings back.  Everything should upgrade flawlessly though as I've done several of these.

testing in this case is as simple as standing up two VMs and upgrading...should only take a few hours at most.

Thanks
