Hi folks. I have a domain with 3 DC's in it, all Server 2012. We previously had some 2008R2 DC's, but they have been decommissioned. I'd like to upgrade the domain functional level, however having some issues with it. Here is the status.
Current forest functional level: 2008 R2
Current domain functional level: (shows as blank)
When I choose 'raise domain functional level', I get a message that says 'you cannot raise the domain functional level because this domain includes active directory domain controllers that are not running the appropriate version of windows'. If i save the CSV to tell me which ones, it shows me two of my 2012 DC's, as follows:
| mydomain.com | DC1.mydomain.com | Windows Server 2012 Datacenter 6.2 (9200) | |
| mydomain.com | DC2.mydomain.com | Windows Server 2012 Datacenter 6.2 (9200) | |
The 3rd DC, not shown, is Server 2012 R2 Datacenter. Do I just need to upgrade these two DC's above and then I'll be able to upgrade domain functional level? Or is there likely some other issue here? Thanks.
