So I am about done testing upgrading my test environment from Win2008 R2 to Win2012 R2. All my DCs are now Win2012 R2; all the DCDIAG logs look clear; all my DFSR errors cleared up (once I learned about the DFSRDIAG POLLAD command).
So I went to do the final step, raising the forest and domain levels. I raised the forest level from Win2008 R2 to Win2012 R2; that went fine. When I went to raise the domain levels (I have a parent and child domain structure), both had already been raised to Win2012 R2 levels. I'm presuming that happened when I raised the forest level. Is it supposed to automatically raise the domain levels at the same time the forest level is raised? This seems odd to me. Oh, I see no errors, and I was going to raise the domain levels anyway. I'm just a bit confused about how (or why) the domain levels rose when the forest levels rose. Is that normal? Thanks
