# Updating

It is quite important for operators to check this file before updating their
production instances, as it may contain information that is critical for good
continuity of the services.


# Kinds of breaking changes

## Nextcloud upgrades

Nextcloud upgrades must be carried out in a very specific order, if you follow
DD closely you should not have issues with this on 2023 and beyond.

However, if you run an older instance, please find the
**2022-12 - Nextcloud 24** section on this document, and follow the commands
closely.

Further major upgrades will be documented here too, but they should have
little to no impact.


# Important changes in reverse chronological order

## 2023

### 2023-03 - Nextcloud 25.0.5 + NC Docker rework

Update version to 25.0.5 and rework its docker image

The image now manages volumes and configuration in a better fashion,
thanks to that we achieve an image that is closer to the original one, but
gets the plugins that we want and the configuration that we want for
integration with DD.

You can now define `BBB_HOST` and `BBB_API_SECRET` as variables in dd.conf,
which are used to configure the corresponding plugin on Nextcloud.

You can also define a list of custom plugins to enable/disable in Nextcloud
with the dd.conf variables: `NEXTCLOUD_PLUGINS_ENABLE`,
`NEXTCLOUD_PLUGINS_DISABLE`. See `dd.conf.sample` for more information.

If upgrading from previous versions, you probably will want to check the
permissions assigned to the `user_saml` plugin directory.
You can also force its reinstallation with proper permissions with:

    # Usually SRC_FOLDER in dd.conf is /opt/DD/src
    rm -rf "${SRC_FOLDER:-/opt/DD/src}/nextcloud/custom_apps/user_saml/"
    # Restart the NC container (only if previous command runs after upgrade)
    # docker-compose restart dd-apps-nextcloud-app
