Changing servers for business rules deployment

In our migration to webmethods 8 we changed server names as we have 7 and 8 running concurrently in dev.

In order to deploy our business rules to the integration server, I loaded them into Blaze 6.8, but I didn't see a way to change the server.  Searching the files in the repository while blaze was closed revealed 2 places where the hostname and connection info is stored in plain text:
<Project Name>

  <instance ref='IS Host'>
   <instance ref='value'>
    <value>hostname</value>
   </instance>

<Project Name>.innovator_attbs

 managementProperty.IS\ Host=hostname

That worked, then I had to regenerate my business object model from IS.  The object hadn't changed, but would not sync up.  After regenerating it deployed fine.
