Summary of the issue you are facing:
I copied an existing Nextcloud instance to a new server with a different path for the data folder and a new FQDN for the server.
Besides changing config/config.php as needed, I also updated the database, table oc_storages so the record for the local data storage contains the correct path (local::/mnt/nextcloud-data).
At a first glance everything seems to work - but most Collectives pages don’t show up at all. I check oc_collectives_page - all file IDs (file_id) also exist in oc_filecache (fileid).
After a file scan (occ files:scan --all) the Collective pages show again, but only in alphabetical order and without emojis.
I can manually rearrange all pages and manually set emojis again - but since I have many existing Collectives with many pages this is not really practical.
So the question is:
What is needed to make Collectives work again, when moving the data folder to another location?
