Upgrade to Grafana v8.5

We recommend that you upgrade Grafana often to stay current with the latest fixes and enhancements. Because Grafana upgrades are backward compatible, the upgrade process is straightforward, and dashboards and graphs will not change.

In addition to common tasks you should complete for all versions of Grafana, there might be additional upgrade tasks to complete for a version.

Note: There might be breaking changes in some releases. We outline these changes in the What’s New document for most releases or a separate Breaking changes document for releases with many breaking changes.

For versions of Grafana prior to v9.2, we published additional information in the Release Notes.

When available, we list all changes with links to pull requests or issues in the Changelog.

Note: When possible, we recommend that you test the Grafana upgrade process in a test or development environment.

Back up Grafana

This topic explains how to back up a local Grafana deployment, including configuration, plugin data, and the Grafana database.

Back up the Grafana configuration file

Copy Grafana configuration files that you might have modified in your Grafana deployment to a backup directory.

The Grafana configuration files are located in the following directories:

  • Default configuration: $WORKING_DIR/conf/defaults.ini
  • Custom configuration: $WORKING_DIR/conf/custom.ini
Note: If you installed Grafana using the deb or rpm packages, then your configuration file is located at /etc/grafana/grafana.ini. This path is specified in the Grafana init.d script using --config file parameter.

Back up plugin data

Installing plugins in Grafana creates a folder for each plugin with its associated files and data. Copy all files and folders recursively from this location to your backup repository.

The Grafana plugin files are located in the following directories:

  • Default location for plugins in a binary or source installation: $WORKING_DIR/data/plugins
  • Default location for plugins in a deb or rpm package: /var/lib/grafana/plugins. This path is specified in the Grafana init.d script using --config file parameter.

Back up the Grafana database

We recommend that you back up your Grafana database so that you can roll back to a previous version, if required.

SQLite

The default Grafana database is SQLite, which stores its data in a single file on disk. To back up this file, copy it to your backup repository.

Note: To ensure data integrity, shut down your Grafana service before backing up the SQLite database.

The SQLite database file is located in one of the following directories:

  • Default location for SQLite data in a binary or source installation: $WORKING_DIR/data/grafana.db
  • Default location for SQLite data in a deb or rpm package: /var/lib/grafana/grafana.db. This path is specified in the Grafana init.d script using --config file parameter.

MySQL

To back up or restore a MySQL Grafana database, run the following commands:

bash
backup:
> mysqldump -u root -p[root_password] [grafana] > grafana_backup.sql

restore:
> mysql -u root -p grafana < grafana_backup.sql

Postgres

To back up or restore a Postgres Grafana database, run the following commands:

bash
backup:
> pg_dump grafana > grafana_backup

restore:
> psql grafana < grafana_backup

bash
grafana cli plugins update-all

Technical notes

This section describes technical changes associated with this release of Grafana.

Default data source

The concept of a default data source existed in Grafana since the beginning. However, the meaning and behavior were not clear. The default data source was not just the starting data source for new panels but it was also saved using a special value (null). This made it possible to change the default data source to another and have that change impact all dashboards that used the default data source.

This behavior was not very intuitive and creates issues for users who want to change the default without it impacting existing dashboards. That is why we are changing the behavior in 8.5. From now on, the default data source will not be a persisted property but just the starting data source for new panels and queries. Existing dashboards that still have panels with a datasource set to null will be migrated when the dashboard opens. The migration will set the data source property to the current default data source.
