Migration of OMD site to new VM

Hi tosch
thank you for your quick reply. I use Ubuntu 18.04 on all machines.
The command omd backup mysite - | ssh user@otherserver “cat > /var/backup/mysite.tar.gz” does the trick but since i have to copy around 400GB this taskes forever. Thats why i thought of rsync.
Or maybe the above command once plus restore and then rsync without copying the user-ids maybe?
