Is there a proper, i.e. working method of migrating from one Webdav provider to another? I initially started with Nextcloud, but before I had added more than a few files I migrated to Seafile. That seemed to go without a hitch.
This morning, I tried to migrate back to the Nextcloud instance by simply changing the config parameters, thinking it would see all of the files it now had were newer than those left behind on Nextcloud, and would sync all the newness to it. Rather, it seems to have deleted all of the newer files, and downloaded only those few files which existed on Nextcloud, so at least 70 files are gone.
Any way to save this?
