If you are upgrading from an earlier full release of Capture One (for example, from version 12 to version 20), you will need to upgrade any Catalog or Session created with an earlier version if you want to work with it in the newest version of Capture One. The upgrade process updates the database, allowing you to take advantage of any improvements made. Image variants remain the same as the previous settings and adjustments are managed by the version process engine.
Catalogs produced by earlier versions of Capture One must be updated to take advantage of any database enhancements in the latest full release (e.g., from version 12 to 20). Upgrading Catalogs is not required between minor releases (e.g., 12.0 to 12.1).
- Choose one of the following options to open an earlier version of a document:
- In the main menu, choose File -> Open… and navigate to the relevant document (i.e., with the .coccatlog extension) and double-click on the file.
- In the main menu, choose File -> Open Recent… and select the relevant document from the list. Note that this menu shows only the recently opened documents.
- In the Finder (macOS) or Explorer (Windows), navigate to the relevant document (i.e., with the .cocatlog extension) and double-click on the file.
- Opening the document will display a warning dialog with the options to Upgrade or Cancel. Once the database is upgraded, the variants are not altered and the previous settings and adjustments are preserved from the earlier version of Capture One.
- Click on Upgrade.
