I had problems a few years ago upgrading my Quickbooks Enterprise Solutions - Accountant Edition 18.0 to any newer edition. I used to be able to do it all the time and I think the CEO and other employees didn't pick up how important this was for its past business customers. It seems that the company got off track and it has lost a lot of customers since it delays upgrading, sales and produces flight to other business accounting software solutions. I don't want to lose any of my previous data. How do I upgrade to a newer version? Since I used multiple businesses with one software program, can I use the new software and/or online solution to upgrade without any data loss?
