Since Capture One version 9, I have created over 110 separate catalogs. It is extremely time consuming to use C1 to open each catalog just to update it for every new release. Please consider a batch utility that can update multiple catalogs to the current version installed.
Current workaround
Open each catalog one at a time, update it to the latest version, close and repeat for the next catalog. It takes longer to open and close than the update.
