When converting from Quicken to QuickBooks, we utilized the QuickBooks Conversion Tool, however much to our surprise, it gave 3 choices for additional accounting software to be installed prior to installing the QuickBooks Conversion Tool. We installed the Microsoft Office Accounting 2008 to meet the requirement in addition to QuickBooks which needed to be installed and registered (Pro, Premier, or Enterprise Solutions 2014 or higher). This satisfied the requirements so that the QuickBooks Conversion Tool was able to be installed.
After the QuickBooks Conversion Tool was installed, then Quicken converted to the QuickBooks Desktop platform with all the historical data included. We’re using QuickBooks 2017 Premier.
