Remember - moving the nodes to a new domain does nothing to rebind the data
to new management classes - that only happens during an actual backup.  So
the data will stick around for as long as intended, except for the last
active version of the files.  Those you have to delete manually.  One
practice I've done is to rename the node, putting the date when it can be
finally deleted to the beginning of the name, hence "NODENAME" becomes
"051231_NODENAME".  Moving this node to a new domain, with a descriptive
name such as RETIRED, you can now easily see what nodes are able to be
deleted, and when.  The simple version:  "query node domain=retired" or the
more complex: "select node_name from nodes where domain='RETIRED' order by
node_name"
