Hi there, moliwo.
For now, there's no option to transfer data from one QBO account to another. If your data is on an expired or cancelled account, you can log in to it and reactivate the subscription. Here's how:
Once done, don't forget to cancel the duplicate account so you aren't charged for it. Follow the steps in this guide for more details: Cancel Your QuickBooks Online Subscription.
There are also third-party apps that offer data migration services in the App Store. You can find them here: https://apps.intuit.com/app/apps/home.
Let me know if you have other questions.
