Hi, Thompson.
Ten years worth of information can be a lot of records, and I appreciate your loyalty to QuickBooks. I'm here to help you fix the error 6190, 816 and work with QuickBooks smoothly.
Error codes 6190 and 816 happens when another user is logged in to the company file in a single user mode. To isolate the issue, please make sure to update your QuickBooks to the latest release to fix common issues with your file. From there, disable multi-user access. Here's how:
- Access your QuickBooks company file as the Admin.
- Go to the File menu, then select Utilities.
- If Stop Hosting Multi-User Access is listed, choose to Stop Hosting Multi-User Access.
Once done, create a backup copy of your company file. Then, download and install QuickBooks Tools Hub, then run the Quick Fix my Program. This is a built-in tool that auto-detects and auto-fix data damage issues within QuickBooks.
- Download the most recent version (1.4.0.0) of the QuickBooks Tool Hub.
- Locate the file you downloaded (QuickBooksToolHub.exe).
- Follow the on-screen steps to install and agree to the terms and conditions.
- From the tool hub, click Company File Issues.
- Choose Quick Fix my File.
- Click OK when it completes and launch your QuickBooks.

On the other hand, yes, you can get your past year/s data to start a new file. However, you need to prepare big storage that's capable of saving larger data.
Another option is to reduce your file size but leaves all the detailed transactions. You can use this link as your guide: Use the Condense Data utility.
