We went from Windows 2003 functional level directly to Windows 2008 R2 on both forest and domain 2 ½ years ago. We did it almost immediately after getting rid of the Windows 2003 DCs and at the time we were on Exhange 2007. We also have 1 forest and 1 domain, but with 1 site.
I'm not saying that rushing into it was the best way to go about it, but we didn't have any issues at all. We have over 50,000 user objects, maybe 20,000 computer objects and over 750 GPOs. Charlie Sullivan Sr. Windows Systems Administrator From: [email protected] [mailto:[email protected]] On Behalf Of Melvin Backus Sent: Wednesday, March 05, 2014 12:54 PM To: [email protected] Subject: [NTSysADM] Forest Functional Level change I'd like to enable the AD recycle bin functionality in our domain and in order to do that will need to raise the functional level from 2008 to 2008R2. So far I haven't run into anything to worry about with that but wanted to ask if there were any gotchas anyone had run into during the process. I've done a few of these in the past with no issues but we've since added Exchange to the mix so that's my main concern. Single forest, single domain, multiple sites. -------------------- Melvin Backus | Sr. Systems Analyst | Byers Engineering Company | 404.497.1565 Service Desk | 404-497-1599 | http://servicedesk.byers.com -- There are 10 kinds of people in the world... those who understand binary and those who don't.
