Transfer catalog back from LR CC to Lightroom Classic

There are a few ways of migrating back to Classic, though none are perfect. If I was doing it myself, I'd probably do this:

1. Create a new LR Classic catalog.

2. Change the Classic Preferences>Lightroom Sync tab to set my preferred location for the downloaded "LR CC ecosystem's images", and I'd also enable the option to use sub-folders formatted by capture date.

3. Then enable the catalog to sync with the cloud.

4. All existing images in the cloud will then download into the Classic catalog, the images will be stored where I have chosen.

5. During this process, all edits will be retained, all images in Albums in LRCC will appear in Collections in Classic, but any Album Folders created in LRCC will NOT appear as Collection Sets in Classic, I would have to manually organise the collections into sets.

6. Any keywords added in LR CC will NOT appear in Classic. Any location data automatically added from GPS data in LR CC will not appear in Classic (though the GPS data should do, meaning that reverse geocoding in Classic should still work).

7. When done, I'd then disable the Classic catalog from syncing (if I had no intention to use the cloud at all).

A couple of other ways:

2. Use the Adobe Lightroom Downloader to download all the original images in the cloud (though I think that would not include any edits), then import the downloaded images into a Classic catalog.

3. Export all the original images in the cloud using the "Original + Settings" option, which should allow edits and keyword data to be retained. However, on subsequent import to a Classic catalog the album/collection information would be lost (it's one of the data types that isn't included in XMP).

Probably a toss-up between 1 and 3, but as I said none are perfect.
