Hi there, Jackson. While you can't migrate those files directly, you can use a QuickBooks Desktop (QBDT) trial to open your backups and move them over to QuickBooks Online (QBO). Just make sure your computer meets the requirements for the 2024 QBDT trial first, and be careful not to register the trial version, as that might actually lock you out of the software.
Once the trial is installed, you can open your company files or backup and start the migration. Just a heads-up that you have a 60-day window from the time you create your QBO account to get your data moved over. You can check out this article for the full step-by-step guide: Move your QuickBooks Desktop company file to QuickBooks Online.
While you're transitioning to QBO, feel free to reach out if you have any other questions.
