photos in icloud photos library

[mrgreeneyes]

Hello,

can someone confirm that if I reupload my photos library will it overwrite whats already in icloud, or will it just add to it?

I have about 20,000 photos in icloud that I want to remove and reupload my new updated library.

I’m confused....

If you’re removing it then re-uploading then why are you worried about duplicates?

I do know that it’s smart enough to do the following.....

Let’s say I take 3 photos with my phone that didn’t sync to my iPad, if I were to air drop 1 of them when it finally syncs (with iCloud) it will not create a duplicate for the other one that I airdropped
