COPY FOLDER STRUCTURE WITH FILES AND PERMISSIONS

robocopy \\source_server\share\directory \\destination_server\destination_share\directory /copyall /e /r:0 /w:1

Select allOpen in new window

Will copy all files from source to destination including all attributes, and all subdirectories.

If you use /mir, it will make the destination look like the source, including by deleting files at the destination that are not at the source.

You can run the command multiple times to make incremental updates. This is often done on busy file servers. The first copy may take days. The next runs will go much faster.

Of course, if these servers are VMs like 99.999% of all servers should be these days, just disconnect the VMDK/VHDX from the old VM and attach to the new VM. Migrate share information via registry updates.

use robocopy with the /secall
xcopy  /T          

Creates directory structure, but does not copy files. Does not include empty directories or subdirectories. /T /E includes empty directories and subdirectories.

Save yourself tine and use dfs management if this is an AD domain

It will synchronize as Sara being, modified/added.

DFS Replication is risky. Just this week I worked with someone that lost most of their files because they didn't understand what primary meant when starting DFS Replication. IMHO robocopy is faster, doesn't require monitoring for failure, consumes less disk space, and takes less I/O.

FYI, of this is an active share, you need to rerun this command until you are certain that no user is still accessing it and making changes.
