You set up all your vaults under the same folder. You 2-way sync that folder to a cloud folder- Dropbox, MEGA, sync, box- whatever. You then create a folder with the same name on another device, and then use the client for your cloud service for that platform, and then set up two way sync with that folder on the cloud.
Works great with my Android-PopOS system.
Also tried it with Android-macOS, and iOS-Windows.
