Import from Lightroom wonky
I'm using both 20.0.4 and the unreleased beta. I've tried importing my Lightroom Catalog (ca 85,000 images) to both versions. While the catalog imports, there are lots of things happening that shouldn't be happening. There are photos that were deleted in Lightroom (and removed from the disk) whose echoes appear in the Co20 catalogs. Cards I've imported into Lightroom are showing up as cards with photos that are, naturally, missing because the source is obviously not there. In short, to successfully import a Lightroom catalog from the latest Lightroom Classic 9.2.1, CO20 must only import what is there, not what is no longer there. The amount of effort required to clean up the catalog should not be this great. Hopefully, this can be resolved in a future release. As it is, I'm going to only have to use current photos, not the entire catalog as I don't have enough time, even in Covid lockdown, to clean this much up.

They have long been removed from Lightroom, Lightroom's database has been optimized, the trash is empty, and I don't have Adobe Cloud activated anywhere.

Marc, I have no experience about importing from LR directly but C1 must be finding some LR data to feed it. No matter that you think there is nothing to find.
Does LR offer a facility to create a new, clean, catalogue containing ONLY what you know to be the currently "real live" images?
Might there be vestigial collections/albums/something like that which still exist in the LR catalogue database - maybe even with thumbnails, but which you never see not have any obvious means to access?
Bear in mind that C1 has no means of following the way the LR functionality guides you through what it believes to be active data. Maybe also no way to cleanse the database reliably for data that some higher level control does no know about.
Are you seeing images or just references to images?

What I think is happening is that even though I have a fully 'clean' LR catalog named LR9Classic.lrcat with connected files, there are other catalogs in the same folder from images that I don't include in the imported catalog, but have squirreled away for other, unrelated purposes. It appears that although these catalog files in no way link to the named catalog above, C1 is finding them and importing them anyway. That seems to account for the 3500 image difference between my 'clean' LR catalog, and the C1 import from THAT catalog. I've deleted the C1 catalog, moved the other LR catalogs elsewhere and am trying again. In no way should C1 find unrelated catalogs, but maybe if it finds a folder that has .lrcat files in it, it attempts to import all of them. I'm just spitballing here, but the behavior is unexpected and annoying. It takes close to 5 hours to import a LR catalog with that many images on an iMac 2019 with an i9 processor, 64 GB RAM, 2 TB SSD, and 8 GB of dedicated VRAM.

In some instances, there are actual images that I know not to be in the catalog, and in other instances, there are references to images that C1 can't seem to find. I'm about 1/10th of the way through re-importing the Catalog to see whether moving the unrelated catalogs out of the same folder makes any difference. Will post my findings later when the results are in.

I'm beginning to think that my conclusion above is, in fact, what is going on. With the extraneous and unrelated catalogs in the same folder as the main Lightroom catalog, the initial import says it is going to import 84,566 images. With those extraneous catalogs removed (remember, they are unrelated to the main catalog), the initial count says it will import 81890 images, which is the exact number recorded in my main LR catalog. We had a power outage last night and my import of the 81890 images got stopped halfway through. I've restarted the process this morning and 3 hours out I'm only 3/8ths of the way through. It is an incredibly slow process, especially with the hardware I'm running. I wonder if there is anything that can be done to speed this along in future versions.
So, this is both a feature request, and a potential bug report. I'll wait until the full import is done before I draw any conclusions about the nature of the bug.

It is definitely picking up stuff that isn't in the primary Lightroom catalog. I accidentally left a stray piece of another catalog (a support file) in with the primary catalog file. C1 20.x picked it up, catalogued it and reported the files missing. So, I can confirm that this bug is reproducible. Moreover, it took nearly 9 hours to import 81,890 images on a 2019 iMac with the i9 (8 core) processor, 64 GB fast RAM, 2 TB PCIe SSD internal drive, Radeon 580x 8 GB video card. Nothing else was running and I had all energy savings turned off. Even then, opening the catalog required the software to recalibrate the GPU, and it had to painfully build previews. Not a wonderful experience, unfortunately. I can't understand why it should take that long to I import a catalog.
