Thanks for reaching out to the Community, @ter88meh.
I want to ensure that you'll be able to restore your data on your QuickBooks Desktop 2019.
Yes, this is updated. If you've created a backup copy for your company file, you can restore it directly to your QuickBooks Desktop 2019. However, if you encounter any error upon the restoration process, you may refer to this article for some troubleshooting steps: Restore Failed, when you try to restore a backup.
However, if you need further assistance with this process, I'd suggest getting in touch with our Customer Care Team. They have the capability to do a remote-viewing session that can walk you through the steps.
There you have it.
Feel free to post again if you have any other questions with this concern. I'll be around to help you out. Wishing you and your business continued success.
