====== Migrate Windows Fileserver using Robocopy ======

Migrate [[:wiki:windows:server:fileserver|Windows Fileserver]] using [[https://en.wikipedia.org/wiki/|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
<code>

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

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

</code>

**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 **D**ata, **A**ttributes, **T**ime Stamps, **S**ecurity, **O**wner, a**U**diting 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.

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

</code>

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