Want to consolidate all photos libriaries into one.
Help please I'm pulling my hair out.
I have several different photos libraries on different imacs and external hard drives as well as other miscellaneous photos needing a home.
I would like to create a new, single 'master photo library' with everything merged into it. As I merge in the old libraries I want to delete them, so I can have everything saved in only one place and free up lots of disc space on my imacs and external drives. Some of the old photo libraries have duplicate photos and videos and some are old back-ups, and so ideally I would like the new master library to avoid importing duplicates.
I thought it would be a simple matter of creating the new master library on icloud photos. To this end I have purchased a 2TB storage plan.
So far I have labelled the first old library as the System Photo Library and automatically uploaded all of the contents about (30,000 photos and videos) to icloud photos.
I now want to upload/merge another library into but need to understand how to do this. I don't want to save the new photos onto my imac containing the first library as the idea is to use the new icloud storage, not the imac storage.
I want to worry about how I view the icloud library through other devices later, at this stage I just want to create a single library I can access from anywhere.
Heeellllpppp!!
Many thanks.
