Migration
Changing tools should not mean losing years of organization. A Lightroom Classic catalog contains more than file references: it carries selections, ratings, keywords, collections, and editing history.
Import read-only
Obscura Catalog opens the .lrcat file in read-only mode. The original catalog is not modified, which makes the migration safer and easier to test.
Preserve curation
Ratings, color labels, picks, rejects, keywords, nested collections, virtual copies, and stacks are carried over into Obscura Catalog: keywords become tags and thesaurus terms, virtual copies become named versions, stacks become relationships between files.
Keep development history
Develop settings and history are archived for reference. Obscura Catalog does not develop RAW files: it keeps the Lightroom adjustments for the record.
Validate after import
After migration, check representative projects: collections, virtual copies, RAW+JPEG pairs, captions, and keywords. A good migration is verified, not assumed.
