Hi experts,

I think this is quite a simple question.
Following scenrio:

I set up a new Windows Server 2016
I initially robocopied (/E /V /L /COPY:DAT /TEE /R:1 /log:) a file share from my old fileserver (without dedup) to a new one when dedup was not yet activated on the target.
After that I activated dedup (59% rate) and I have an optimzed state of the share on my new server.
I would now like to sync the old share (which is still in production) with the new one.

At the moment I am trying the same robocopy command again (as dryrun) and in the robocopy logfile I see entries with "equal" and some with "optimized".

Would the sync work in that scenario? (Target optimized, source unoptimized)
I`m definitely only copying a folder, not the whole volume what did make problems with dedup for others, how I read.

Many thanks in advance!
