Converting data from Quicken to QuickBooks (or vice-versa)

The Quicken program cannot convert QuickBooks data because QuickBooks data files contain many elements for which Quicken has no support mechanism. QuickBooks products of the same or newer version of your Quicken product, will generally convert Quicken data files (except your Investment Accounts).

Note: Quicken to QuickBooks data conversion is a one-way conversion. Once a QuickBooks conversion attempt has been performed on your Quicken data, the data can no longer be opened in Quicken. For this reason you should make a backup of your Quicken data prior to any conversion attempt or perform the conversion on a recent copy of your Quicken data. 

For more Quicken/QuickBooks conversion information, please visit the QuickBooks Support Web site.
