Welcome to the Q&A Forum

Yeah, wish I could give you a simpler answer, but I'm afraid it might end up being a little tricky. Hit the biggest problems first, and at least you can manage time/money a bit. The one bright side is that the rules should be no harder to code in ColdFusion than anything else (PHP, ASP, whatever). It's just the core logic that's tricky.

It may depend on how the host of the draft version has it set up. For example, Adobe Business Catalyst settings automatically block all test sites from being crawled by search engines. Can you inquire if the search engines are allowed to crawl their archived or draft site? I have also been amazed at how many times someone puts a "back up" copy somewhere else on line.  Opening up the discussion may save you duplicate content troubles ahead.
