Our current environment consist of 1 OnPrem DC, 1 Colo’d DC (2008R2), DirSync, ADFS 2.0 and a DMZ’d WAP. I am evaluating retiring the OnPrem DC and adding Azure AD Premium subscriptions. We will be standing up a new colo’d Win 2012 and upgrading to AD Connect. The goals are to add SSO and remote self-service password reset. Will we still need the WAP server for O365, and are there other things I need to consider?
