Lightroom to Lightroom Classic and back for Duplicate removal?

[Brave_Sunbeam6595]

hi Everybody, I've recently decided to go "all in" with Lightroom CC. 

I have started moving many hundred GB of images to CC, and started spotting many duplicates.  After searching around, it seems like there is no way to identify duplicates in Lightroom CC. Is this still true (Feb 2025)?

If so, I do see Lightroom Classic has an add-on for finding duplicates... so I'm wondering if people would recommend moving everything from Lighroom CC to Lightroom Classic for de-duplicating, then back to Lightroom CC? 

Seems like a lot of work, but I'm not sure other options. Is this an idea people have tried and would recommend? Or is this asking for a headache?

Do you mean during import? There is no duplicate finder in classic either that I know of except in the import panel. Or are you talking about one of the paid third-party plugins to do this (see here:https://www.lightroomqueen.com/clean-duplicate-photos/)? Without one of these plugins this is not a trivial thing to do. Indeed there is also no option to identify duplicates in Lightroom Cloudy so yeah if you are referring to the paid plugins in Classic and have a lot of duplicate files, this might be something you might want to do in Classic first.

Yes, that plugin she refers to is the only option I've seen for finding duplicates....  I'm just loathing the needing to download everything from the LRCC Cloud to do this, just to then re-upload it.

We really need either native or third-party visually similar duplicate image finding. I have so many photos from so many sources, including a high-speed scanner to capture all family photos. I have duplicates where the original digital photo is in, plus a scan of a print-out someone made at some point, plus instances of multiple printouts in different physical albums making their way in. This was very straightforward in Lightroom Classic (I used this tool, for example: https://www.mindgems.com/products/VS-Duplicate-Image-Finder/VSDIF-About.htm). I need a tool like this to work in Lightroom CC, whether native, third-party, paid add-on, and have been waiting many years.
