Accessing the repository from a previous version
When you upgrade to Tableau 2020.3 from previous versions, your repository is upgraded. Any bookmarks, workbooks, and data sources that you had in your old repository will still be accessible by the application. In addition, the new sample data sources and workbooks will replace the old samples unless you have modified them and saved them as your own.
Note: Your recent workbooks are automatically imported and restored to your Start page along with your recent connections list and any organization-specific settings on the Discover pane.
Accessing the repository from a beta version
If you have participated in the Tableau Software Beta program, you also have a beta repository. While this folder will still exist after you install Tableau 2020.3, the application will no longer access it. To make your beta workbooks accessible in Tableau 2020.3, copy the workbooks from the beta repository to your new 2020.3 repository.
