This is a simple setup:
- one SBS 2011 Standard server (running Exchange 2010 and all other SBS aplications)
- one Windows Server 2012 R2 member server that is NOT a domain controller (replica or otherwise): it does remote access, Workstation backups, etc.)
Under actual WSE implementations, only one server can have the Essentials Role: if we migrate SBS 2011 to Windows Server 2016 with the Essentials role, how are the existing Workstation backups (and stuff) handled in the scenario?
PS: I do not see my previous emails in your system.
Not sure what you are trying to do here. I don't think it a supported configuration to have SBS 2011 around with a member server doing Essentials Experience stuff. I would remove the SBS 2011 completely and have a new DC in place and install the Essentials Experience role added. Client Computer backups cannot be migrated so you need to start on the new server with new backups
