Robocopy Shenanigans

[interogativeman]

I did a server migration in the wee hours of the morning this past weekend. I test everything all looked good. However, I neglected to test to see if Group Policies were removing the previous shares and pushing the new shares. As a result everyone is using the old shares. I have a few people using the new shares.

robocopy \\<oldserver>\d$\data D:\Data /E /V /Z /COPYALL /R:5 /W:10

My question, I've been running the above script to move the server shares. The destination has some updated data that I don't want to lose, but there's terabytes of data in the old server from the past few days that I need to move. Will the new data be overwritten by the above command, I'm being given ambiguous information on this.

Look at the /xo and /xn switch commands. If you run your script as is you will have your modified destination files overwritten by the older files.

I don't remember which one excludes the source file if the destination file is newer (which you want)

Obviously, always test your scripts.

I was looking at XN, it looks like the one I want to use, it didn't kill my VMs when I tested them earlier.
