Migrate (again) from LrC to Lr - three related questions

[PNWPhotoWalks]

Lightroom Version

LrC V 13.0.1 / Lr 7.0

Operating System

1. macOS 14 Sonoma

Hello. After reading the new ‘Adobe Photoshop Lightroom Edit on the Go’ publication (which I think is great) and reviewing https://www.lightroomqueen.com/lightroom-cc-vs-classic-features, I’ve decided to migrate (again) from LrC to LrC. I want to migrate ~50K images. I have adequate bandwidth and local storage to perform a migration. For guidance, I’m following the steps listed in the ‘Migrating from Lightroom Classic’ (pp 66-68) in ‘Adobe Photoshop Lightroom Edit on the Go’.

Prior Migration History

Several years ago, I migrated from LrC to LR. I used the Migration Assistant utility. I subsequently reverted back to Lr because of the limitations I found in Lr, at that time. I did not delete my LrC instance or Creative Cloud account when I started using Lr again as my primary platform. As I recall, however, I did manually delete all of my LrC <-> LrC synced images. Ongoing, I’ve been only syncing preview copies.

Questions

1. Will Lr know that I previously migrated from an earlier LrC catalog, e.g., Lr retained a .lrcat file reference, Lr or LrC set a ‘migration completed on xx/xx/xxxx date’ flag or similar?
2. If so, will I be prohibited from performing another complete migration? My motivation is to migrate all of my LrC keywords, one time. I do not have any keyword hierarchies.
3. If I’m prohibited from performing another complete migration, is there a way for me to “reset” this reference, i.e., to force a new complete migration?

Thanks in advance for your help!

P.S. to Lightroom Queen. In ‘Adobe Photoshop Lightroom Edit on the Go’ on page 66, the second sentence is this paragraph doesn’t seem complete to me.
“Most of your organization and edits are transferred during the migration process. Many Lightroom Classic features don’t exist in Lightroom.”

Before you jump, what sent you back to Classic last time?

If it complains it's already migrated, you can use Classic's File menu > Export as Catalog to export everything to a new catalog, open the new catalog and let it take over syncing, and then migrate that. That should get past that barrier.

Yes, I think you're right, thanks! I've made a note to update in the next release.

Most of your organization and edits are transferred during the migration process. Some Lightroom Classic features don’t exist in Lightroom, so their data is ignored or converted during migration.

Thanks, Victoria. In 2017, after I performed my original LrC-Lr migration, I discovered that I needed many of the features that Adobe subsequently added to Lr. Specifically, support for multiple catalogs and facial recognition.

The following paragraph, which is from your ‘Lightroom cloud ecosystem vs. Lightroom Classic—which do I need?’ webpage, nicely summarizes my motivation to now migrate to Lr: “If you’re trying to fit photography into a busy lifestyle, with a mix of phones, tablets, laptops and desktops, having your photos available on every device is a massive advantage, which makes Lightroom (cloud ecosystem) an obvious choice.”

My busy lifestyle is no longer work and young children, but now travel. My wife and I just returned from a month of trekking and traveling in the UK.

P.S. If interested, I also mentioned my migration in my 1/1/2020 intro message (my first two links are broken):

I hope you and your family have a nice Thanksgiving!
