once you copy the files to the new file system.  create a single file,
can be anything on the new file system.  Then mount the new file
system over top the old file system.  You can then look for the new
file you created to make sure you are looking at the new file system
not the old.  run things that way and make sure you don't have any
problems.  once your sure your good to go then delete the old
filesystem.
