My response to the VP would have been (mind you I have had a few more minutes to think about this than you did), "We'll have to conduct an audit of our own, see what needs to be fixed. Can I meet with you after this meeting to find out who I'll need to work with when I get there?". I think a couple of days in the new company's office, taking their IT folks out to lunch/dinner/beer would buy a lot of goodwill and make sure you get a feel for how everything is put together when you start working on this project remotely.
