Hello,
We're looking to upgrade our ADFS from 2012 to 2016.
Currently we have 2012 DCs running at 2003 domain and forest functionality level. Can ADFS 2016 work with 2012 DCs running at 2003 domain and forest functionality levels?
Looking at below, it requires a 2016 schema, but I'm not sure what version of DC and functional level that requires.

Thanks

A 2003 domain functional level is sufficient to add the first 2016 domain controller.

Hi,
So just to confirm, I can add a 2016 DC and run ADFS 2016 whilst still keeping 2003 domain and forest functional levels?
Thanks
Yes, 2003 DFL is the lower limit but still sufficient.
