I don’t think this is the same thing.

Opencloud.eu seems to have been started so they could offer hosting services to EU clients and essentially compete with MS teams and others. You can download and run their version directly. This isn’t a fork the way that opencloud > nextcloud was a change in governance.

OCIS seems to have a great open source product that I’m also hoping to switch over to. I’ve been trying to get it connected to my authentik SSO (which I have) and just need to figure out how to get admin users on authentik to show up as admin users on ocis.

That’s the last thing I need to migrate over fully.

I used to be on owncloud then switched to nextcloud at the fork. In all that time through 3 different servers nextcloud has always been the most brittle app I’ve hosted
