5. Verify the copy by running

# diff -r --no-dereference /mnt/old/ /mnt/new/

PS: I'm not sure, if diff might warn about missing sockets or similar. If "cp -a" returned exit status 0, the copy is most likely ok, running diff isn't necessarily needed. If tar --xattrs... returns exit status 0, you can't trust it. After doing a backup by tar always (try to) open the archive. However, making a backup using tar first and then restoring from the archive doesn't make sense at all.
