Is it possible to change the global name in an existing streams configuration (and make any supporting changes in streams to keep everything straight?  Or must you redo stream setup after the change?

Since I'm afraid I know the answer... I know it is possible to restream tables without copying data... but I don't know the steps... can anyone point me to a good example?

Our streams implementation is all symetric bidirectional.

Basic plan is to halt updates, "unstream" as needed, change global name and create new, correct DB links, and re-stream the tables specifying that matching structures and data already exists.  (To avoid copying a lot of data and minimize time and space issues associated with recopying everything.)
