iCloud to NextCloud migration: photos albums

Hello everyone,

I have an user that was relying on iCloud for her photo syncing between iPhone and iPad.

Now the iPad is being replaced with a samsung tablet and I am setting up NextCloud client on both the iPhone and the tablet.

With iCloud, the album structure is preserved between the 2 apple devices (photos are grouped the same way and album metadata is persisted).

I would like to achieve the same with NextCloud, preferrably with an approach as much transparent as possible for the user.

How would that work with NextCloud? Any advise are welcome.

Side note: I have my own nextcloud on prem setup so it can be tweaked if needed
