I actually ended having Quickbooks tech support contact me.  I was very pleasantly surprised at how dedicated and helpful they were.  It was complicated to do this whole process, and it's much better to have the tech support on the phone (especially since there were lots of bumps along the way with some QB error messages).  They escalated the issue several times and followed up when they said they would.  I was very much taken care of.  In the end, it was a success!
