The discussions I had took on a slightly different tone. They gave me some additional information which actually made sense. I do not recall the specifics, but it had to to with the interface which was used to bridge the two systems--that certain functions were inadvertently left out of the final version (something like that).
All I can say is they are acutely aware of it, and are working 24/7 to resolve it and make things easier.
This doesn't let them off the hook, but it is a small consolation that they are aware of it. That said, I repeated that it should have not been cut over until all these things were fixed.
Stay tuned....
