I'm getting ready to promote our current domain from a Server 2008 R2 server to Server 2016. All dcdiag checks and replmon checks are good and looks to be ready. However I've been doing reading on DFSR and realized we are still on FRS.
My question is do I need to migrate to DFSR (this is recommended over FRS) now, or is this done when the new Domain Controller is promoted? Or if I should migrate AFTER I promote my domain to 2016?
