OK, no-one sees to ask question here so I thought I'd have a go 
I've inherited (what seems like) a hastily cobbled together set of BizTalk environments. While it's not a major head-ache, the way groups and accounts have been configured and named in production is different to the other test/dev environments. I'd like to make them consistent, just for my own peace of mind if nothing else.
How can I convince an already active (read deployed, configured and working) BizTalk environment to change the name of things like the BizTalk administrators group or the operators group? Is it even possible without un-configuring everything and having to redeploy all solutions?
