So if we miss that deadline we can never migrate the additional data?!  That seems crazy! 

We are currently paying for our QBD subscription, our QBO Advance subscription and now have to pay a massive sum to migrate and access our historic data, with a shot gun against our head?  Unable to try the other system for a few months to see how we can get on?

I thought the situation couldn't get any worse!  But I was wrong.  You poor things working for such an incompetent organisation!  I am LIVID!  I am so glad I asked the question.
