Thank you for choosing QuickBooks 2020, @elsenorg.
I'm happy to help move your clients from your older version to the new one. You don't need to transfer them, instead, you can create a backup from your older version and restore it to the new one.
Consider creating a portable company file to move your accounting data. You can check this guide for the outlined steps: Create and open portable company files in QuickBooks Desktop.
If you need a full backup, you can check the following articles instead.
