iPhoto events in Photos, don't understand.

Moments in Photos are the new Events, i.e. groupings of photos sorted by date taken.

When the iPhoto Library was first migrated to Photos there is a folder created in the sidebar titled iPhoto Events and all migrated iPhoto Events (which are now Moments) are represented by an album in that folder.

To open the sidebar if it's not already open use the Option+Command+S key combination.

NOTE: It's been reported by several users that if the Event albums are moved out of the iPhoto Library folder in the sidebar they may disappear. It's not widespread but several users have reported that issue. Therefore, if you want to assure that you keep those Event albums don't move them outside the iPhoto Events folder.

There's a way to simulate events in Photos.

When new photos are imported into the Photos library go to the Last Import smart album, select all the photos and use the File ➙ New Album menu option or use the key combination Command+N. Name it as desired. It will appear just above the iPhoto Events folder where you can drag it into the iPhoto Events folder

When you click on the iPhoto Events folder you'll get a simulated iPhoto Events window.

Albums and smart albums can be sorted by Title, by Date with oldest first and by Date with newest first.

1 - wrong - all Photos is all photos in your library - the iPhotos events folder contains albums matching the event you have in iPhoto - albums are not a place or a duplicate - they are just a different was of viewing the photos in your library (all Photos) for organizational purposes - a photo can be in 1000 albums and it still exists only once in the library

2 - I have no idea - please provice more information

3 - you should not trash the iPhoto App as you might want or need it and it can be extremely difficult to get back and it takes very little space - less that 2 GB

4 - when you migrated your iPhoto library all the photos were migrated - there is nothing to merge (and there is no way to merge)

What OS do you have? What version of Phtoos and of iPhoto? How many photos are in the iPhoto library and in the Photos library?

On each system look at the bottom of the photos view and see what the status is - and also in the Photos preferences ==> iCLoud see what the status is - that will tell us if everything is complete or not
