IF initial replication is still in progress, and i robocopy NEW sets of data (to avoid un-ncessary replication of new data)

What is the impact ?

Will DFRS gets confused ?

Confused? No. Not exactly.

Once initial replication has started, new files added to either side
will get replicated once DFS-R finishes the initial sync.

If you try and help DFS-R by copying files manually, DFS-R will see new
files appearing on both sides and it will take even more time to compare
and sync the new files, then go through conflict resolution to resolve
the conflict you just created. Since the files are hopefully identical
there isn't much harm, but it will take more time.

There is nothing you can do to help DFS-R along once the initial
replication has started, you're best off just waiting and letting it go.

Watch your eventlog, raise the staging size areas if needed, especially
during the initial synchronization phase.

I tried this once and there was harm. Even though the files were identical,
DFS-R did not like seeing a new file on the other side with the same name
and had the tendency to just remove it.
