Single user data transfer from S3 primary storage

Hello everyone, i hope you are doing well!

I have read so many posts but still can not figure out if this is possible.

I have a nextcloud instance hosted in Hetzner with primary S3 storage with another provider and i was wondering if it is possible to transfer a single user data from the instance to another instance.

Example: I have 3 users and each of them has their own folders and files. I want to transfer 1 user with all his folders and files to another instance.
Is it possible? If yes, how?

By what i have read so far S3 storage has some limitations but still can not understand if it is possible to do what i want or not.

Please let me know if i am not clear with what i am asking and if you need more info on my setup.

Thank you in advance!!
