I am currently in Windows 2008 AD Mode. I recently introduced 2 Windows 2012 R2 Domain Controller in 1 of our 4 sites.
I am looking to use gMSA feature. However it seems I have to extend the schema.
Is it possible to extend it with only 2 of 8 Domain Controllers being 2012R2?
If so, can on use gMSA on sites that only have 2008 DCs?
