Hi Bill, if you're moving everything, you can probably just update your Internal URL Filters to the new domain and call it good. Everything should be pretty seamless, as long as your implementation doesn't throw any JS errors. You don't even have to create a new report suite if you don't want to.
If you do want to start with a brand new report suite, you'll want to update your implementation to point to the new report suite ID. Arun's links above can give you more information on how you might be able to do that.
Regardless of what you choose, I would highly recommend you test everything prior to publishing it live, and make sure image requests are firing using the Adobe Debugger.
