This is a good general solution, and recommended if you want to set up to
handle things with maximum flexibility, but usually in this sort of
situation the whole tree has the same ACL and there aren't any other
oddities to worry about.  In this case, I often do the moral equivalent
of:

    vos create <volume> <somewhere>
    fs mkm new <volume>
    fs copyacl current new
    rsync -av current/ new/
    mv current old && mv new current
    rm -rf old
