Updating to the latest version of Nextcloud (16.0.3) broke my installation since I do not have a new enough version of PostgreSQL. Upgrading PostgreSQL is not an available option for me to do. Question is: How do I downgrade my Nextcloud installation to an older version without touching the database?
Documentation for Nextcloud states this: “You must have both the database and data directory. You cannot complete restoration unless you have both of these.”
Will I break everything if i just do the following to overwrite the new version with the old?
rsync -Aax nextcloud-dirbkp/ nextcloud/
What is the correct procedure to follow?
