Everything sounds good.  I would add that if you need to keep downtime 
to a minimum, you can replace cp with 2 runs of rsync.  rsync old home 
to new home once while the server is in normal mode (3 or 5).  Then 
bring it into single user mode and rsync again.  The second run of rsync 
will be short as only a few files should be different.  I used this 
method in the past when upgrading a harddrive on my mail server.
