Thanks for getting back to us, @isofos.
As mentioned by my colleagues, when converting from QBDT to QBO, not all files can be converted into QuickBooks.
Overwriting your data that was currently in QBO is unavailable, you'll need to manually re-added the information that doesn't convert.
Also, I'd suggest contacting our Customer Support Team. They have tools like screen sharing that can guide you with the conversion and help you fix in case you encounter any issue.
Here's how:
- Click the Help icon in the upper right of the screen.
- Select Contact US on the pop-up.
- Enter what you're needing assistance with in the How can we help? field and choose Continue.
- Click Get a callback.
- Enter your contact information.
- Select Call me.
You can also look for a third-party app, just click the link shared by my colleague. This will show a list of supported apps that handles importing transactions.
You may refer to the articles shared by my colleagues about converting data from QBDT to QBO.

Stay in touch if there's anything else you need. I'm always right here to help.
