Consolidate two Nextcloud instances into one


I have two Nextcloud Servers/instances running and would prefer to have only one. Is there a way to consolidate the data automatically or have I to do it manually?


MHO: Do it manually, because you could then sort out deprecated files and reorganize its structure and so on.

I did it twice and had a excellent result in cleaning up both servers and migrate it to one.

negative effects: users had to recreate their account-information and passwords, but they we’re glad to do so due to the mess they’ve left behind after a few years.
