I have the following Setup fora small nextcloud instance at the moment:
Nextcloud v19 on a Docker host with the data stored in a docker volume with an LDAP integration.
Now I want to upgrade the installation to Nextcloud v20, add an nginx loadbalancer and have persistent data.
How can I migrate the data from the docker volume to a more persistant storage like bind mount?
What happens with the link to LDAP? Will all the files and users work as usual or do I have to link everything manually?
How can I migrate the database?
