Server 2016 in Server 2008 R2 domain

I’m thinking about adding a 2016 server to a 2008 R2 domain… the DC’s are 2008 R2 and the functional level is 2008 R2. What issues would I experience with adding a 2016 member server? I’m particularly interested in any issues I would experience with group policy being applied to the 2016 memberĀ …
