try the following
cd /vservers.new
dump 0f - /vservers/ref | restore rf -
this makes a copy of your vserver 'ref' to /vservers.new
(you don't have to care about proc/dev/pts umounting,
but, as somebody already pointed out, you have to worry
about applications not able to start from an uncleanly
shut down state ... in this case you could do the following:
vserver ref stop
<the copy process for 'ref'>
mount --bind /vservers.new/ref /vservers/ref
vserver ref start
