how to tell if i´m using DFS or DFSR to replicate sysvol?

how to tell if i´m using DFS or DFSR to replicate sysvol?

My fisrt AD Server is 2008R2 (10 years ago) and over time we added some WIn2012R2 AD Servers

Yesterday i´ve added my first AD Win2016 Server and a warning regarding DFS X DFSR

I´m not entirely sure if i´m not using DFS, so, how to check?

I never did the SYSVOL migration.

C:\Windows\system32>dfsrmig.exe /getglobalstate
Current DFSR global state: 'Start'
Succeeded.

reg query "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\DFSR\Parameters\SysVols\Migrating Sysvols"
    Local State    REG_DWORD    0x0

Based on this article:

http://itprocentral.com/how-to-identify-the-replication-technology-in-use-by-active-directory/

In the new window, look for the msDFSR-Flags attribute, and if the value is 48 then the DFS is being in use. If the value is one of these (null/empty, 0, 16 or 32), then you are in a transition or FRS mode.

My msDFSR-Flags is NULL.

So, i´m using DFS-R?
