Migrate Windows Fileserver using Robocopy

In your new server.

Go to your C:\
Make a folder called “RoboCopy”
Inside “RoboCopy” make a new folder called “Logs”
Inside “RoboCopy” mae a new folder called “Old Logs”

As filename I usually use the folder / drive I'm migrating.

Insert the following code into the *.ps1

$source = <\\OLDSERVER\d$\FOLDER>
$destination = <D:\FOLDER>

robocopy $source $destination /e /zb /copy:DATSOU /r:3 /w:3 /log:c:\RoboCopy\Logs\<FOLDER>.log /V /NP

What are those switches doing?

/E Copy subdirectories recursively, (including empty ones.)
/ZB Use ‘restartable’ mode, and if this fails use ‘backup’ mode.
/copy:DATSOU Copy Data, Attributes, Time Stamps, Security, Owner, aUditing information
/R:3 Retry three times, if you don’t specify this, it will retry one million times!
/W:3 Wait time between the retries above.
/log Will output the log to the folder we created above.
/V Produce output in verbose (detailed) mode.
/NP Do not show percentage progress

After the first run, run the following code to mirror just changes from the old to the new server, usually doing off-work hours.

robocopy $source $destination /e /zb /copy:DATSOU /MIR /r:3 /w:3 /log:c:\RoboCopy\Logs\<FOLDER>.log /V /NP

Afterwords, don't forget to re-share the folder / drive, and change the source on the DFS.
