Hi,
Robocopy will not copy share permissions.
To copy share permissions, please check the following steps:

1. On your old server, open Registry Editor.
   HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Services>LanmanServer>Shares
   Right-click the Shares key and select “Export” it to a file and then copy the file you exported from the old server to the new server.
2. Go to your new server and right-click the registry file and select “Merge”. All the share information will be imported to your new server. If the new server uses the same drive letter, then just restart the server.
3. If the new server uses a different drive letter compared to the old server, you need to open Registry Editor:
   HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Services>LanmanServer>Shares
   Double click the share and then locate the section labelled “path” and change the drive letter to the one of your new file server.
   (You will need to do this for each share that needs a change of drive location. Once completed, please restart the server again.)

Note: the new server has to be essentially identical to the old in terms of where the files are and what partitions they live on.

Here is a guide of robocopy cmd for you to check:

Answer 3

Hi,
Please try:
ROBOCOPY /Mir <Source> <Target>
ROBOCOPY /E /Copy:S /IS /IT <Source> <Target>
The first Robocopy command above will copy data and security for files that have been updated, and the second Robocopy command will refresh file security for all files, without copying any file data.

Or try the command to retain all permisions, ownership & timestamps of the entire folder structure and data (source):
robocopy source destination /E /ZB /DCOPY:T /COPYALL /R:1 /W:1 /V /TEE /LOG:Robocopy.log

Thanks for your time!
Best Regards,
