File Server Migration with Robocopy

I’m in the process of migrating data from an aging file server to a new shiny one.  On the old server the NTFS permissions are all over the place so I really wanted to copy the data to the new server without the existing NTFS permissions and then apply new ACLs on the new server.

I decided on Robocopy to copy the data.  The command line and switches I used are;

robocopy \OldFileServershare \NewFileServerNewShare /MIR /COPY:DATO /DCOPY:T /ZB /r:1 /w:1 /log:robo.log

/MIR mirrors the entire directory structure

/COPY:DATO copes the Data, Attributes, Timestamps, Owner information.  The NTFS permissions are not copied.  Using an S in the above would also copy the NTFS access control list.

/DCOPY:T – Copies directory timestamps

/ZB  – Use restart mode and if access to a file/directory is denied use the backup option (e.g. copy with backup privileges)

/r:1  – Specifies the number of retries on a failed item

/w:1 – Specifies the wait time between retries

/log Outputs the result of the copy to a log file

Using the /log file means you don’t see anything happening in the cmd window whilst robocopy is working.  I like to use which is available as part of the System Center 2012 R2 Configuration Manager Toolkit

CMTrace is a SCCM tool and really good for viewing log files in real time.  Opening robo.log with CMtrace means I can watch what Robocopy do its work whilst it is being output to a log file for me to view later.  This can be handy in case there were any failures or warnings.
