    Hi,

    I enabled iCloud photos on my iphone a few months ago. From that point on, I stopped using iPhoto on my mac. So I have an icloud library for the past few months and an old "archive" iphoto library.

    My idea is to now merge the two. How can I do it without losing any photos?

    - If I enable iCloud photo in my old iphoto library, will Photos.app merge the icloud library with the local library? Will I lose all my cloud photos? will I lose all my local photos?

    - One idea that I had was to enable icloud photos on an empty library so that I can download all my cloud photos, make a backup on time machine, and then try to merge the two libraries without worries of losing anything. How does that sound?

    :)

    When you enable it on your Mac, the new Photos app will just upload all your photos from its library as well. So you should have all from your iPhone and all from your Mac in iCloud and showing on all devices when it's done with all the syncing. Nothing should be lost.

    i still have 200 more photos to upload but for hte moment:

    1) iPhones and iPads show all photos, including all ones.
    2) Photos.app on my Mac only shows old photos, it's still not showing the more recent photos from my phone.
    3) Albums are OK on my mac, but are duplicated on my phone, showing several times each album with 0 photos, and one copy with all photos.

    I'll see if things finally sync properly once the last photo ends uploading.

    A follow-up question: has anyone ever tried merging 2 iPhoto libraries from 2 different computers into 1 iCloud Photos account?

    Specific example:
    - I have converted the iPhoto library on my MacBook to Photos, and uploaded it to iCloud Photos. There are about 7000 photos in the library and they take up 35 GB. All went well and I have all photos synchronised everywhere
    - on my iMac I have an Aperture library. I want to convert it to Photos, then I want to tell Photos to sync it with iCloud Photos

    What will happen? Will the photos from my newly converted Aperture library on the iMac be added to whatever I already have on iCloud Photos? Or will iCloud Photos say "oh look, that's a new 'master' library, let's delete everything and upload this instead", overwriting my MacBook Photos library as well?

    I cannot find a documentation of "conflict resolution" in iCloud Photos. Has anyone tried? Any educated guesses?
