Hello Tim,

Wow, great documentation!   That really clears a lot of the terminology 
for me.

We have to remove our Win2008R2 Servers before Jan2020.  

Hopefully Samba 4.11.x will permit us to join a Win2012R2 Server at a
2008R2 functional level... 

Your documentation gives steps on how to do this.  But I need some

Here's my understanding of the workflow:

 1. Upgrade Samba DC's to version 4.11.x
 2. Promote domain to schema 69
 3. Transfer FSMO roles to Windows 2008R2 Server
 4. Join Windows 2012R2 Server to domain
 5. Delete Windows 2008R2 Server

When I join the Windows 2012R2 Server to the domain, how do I make sure
that it doesn't try to upgrade the functional level to 2012R2?

Do you know if 2012R2 functional level is planned for Samba 4.12.x ?

Thank You!
