Hi there, @Tops.

In QuickBooks Online, you can only export your reports and lists from one company to another. You'll have to manually enter your transactions with the new one.

I also suggest visiting our App center to look for an application integrated with QuickBook that can help export all your data. You can search for them through the Apps tab in the left panel and enter the keyword in the search field. You can also click this link for app collections reviews in QuickBooks: https://apps.intuit.com/app/apps/home.

Please let me know if you need further assistance. I'm always here to help.
