Interesting but I haven’t found how to mount decomposefs with rclone, do you have any examples? I succeeded with WebDAV but it doesn’t seem very reliable

Another thing: migrate the data with rclone at the moment is not working very well , it’s easier to install a desktop client and copy the data with it

Probably you missed it: https://owncloud.dev/ocis/guides/ocis-local-docker/

Btw also ocis store the files in its own format
