No one at QB help line knows what is going on. I’ve spent 4 hours on the phone. It seems the Sage 50 backup file in CANADA is not comparable with dataswitcher. 
I had to find out in YouTube you need a .ptb file for dataswitcher. The article says absolutely nothing about what file is needed….

the information is wrong and after 4 hours on the phone, left more confused than when I first called, I’m wondering if it’s even worth switching to QB if your help is so terrible??
