Why should the "whole thing be out of our hands".  It is your product therefore if one has paid their sub it is your responsibility. I have been a customer of Intuit for 30 years (from Quicken back in the day) and I really expect a better more responsible service
I admit to being behind and have not migrated in time - I have been ill - but now trying to do that. I have signed up AND PAID for QBO but trying to migrate is a nightmare. Some of your web links are out of date stating that you can still upload your QB DT files however you can't open them now (though interestingly I could on 4 July -ie after your deadline)  I am quite happy to migrate the old files to QBO and more than one (2 only in total) but you should offer better support and not say "whole thing be out of our hands".   

thank you
