Mise à niveau du catalogue LR V6 classic vers LR classic V 14.1

I am beginning to suspect that any version of Lr-Classic later than v13.2 (ie. 13.3, 14.0, 14.01) is not capable of upgrading catalogs from Lr v6. Perhaps because of the changed database structure introduced in v13.3 of LrC.

@Jean-Philippe37565092aejr  I can only suggest you *** try-

-Install v13.2 in the Desktop App and try opening the v6 catalog with 13.2, then later upgrade again to v14.0.1

If that fails your only option might be to save metadata to all files in Lr6, then import all files to a new catalog in v14.0.1. You will preserve only the last develop version of images, no History, no Collections, etc.

***But the important consideration is- You do need a paid subscription to the Photography Plan. If you don't subscribe you may have 'killed' your access to develop functions in Lr6 by installing the Desktop App.
