ASR Studio ? How to copy to new Environment with change of Docbase

I have over 900+ reports configured in our MODEL Office environment using ASR Studio

   The Docbase is let's say YYYYYY

I now want to copy those configuration to our UAT environment using a different Docbase say ZZZZZZ

Our environments are setup exactly the same for directory structure and other items all except the DOCBASE

I believe I can COPY the XML files over and that should mostly do it.

But then HOW do I easily change the DOCBASE under the "Store in Documentum Docbase settings"

   with have to go into each workspace and change it manually.

Another thought does the "Docbase" have to be setup in "Store in Documentum Docbase settings"

  Is there a way for ASR Studio to have a default configured ?

Thanks

Any help would be appreciated
