Move user between Nextcloud instances

Hello everyone,
lets say i have 2 Nextcloud instances,
is there any way to move users from Instance A to Instance B (and keep all their settings in several apps like news etc)?

No, there is no command yet. There should be a feature request somewhere on the bugtracker but I can’t find it at the moment (if you can’t find it, put a feature request yourself and leave a link here):
