Database Backup
Upgrade Grafana
Updating Plugins
Restart grafana-server
1. What is Grafana
Grafana is an open-source visualization tool. It does not store data but consumes data sources to create real-time graphs displayed on custom dashboards.
The data source includes InfluxDB, Prometheus, Graphite, CloudWatch, and more.
Now let’s begin upgrading Grafana v7.0 to v8.0 in Ubuntu
3. Database Backup
Before upgrading it is good to take a backup of the database as well as the plugins installed
During startup, Grafana will automatically migrate the database schema (if there are changes or new tables). Sometimes it might cause issues if you later want to downgrade
SQLite
Since we are using SQLite as the database for Grafana(default one) we would do the following steps to take a backup
Navigate to /var/lib/grafana/grafana.db and copy the grafana.db to a folder.
If you installed Grafana in a custom location using a binary tar/zip it is usually in grafana_install_dir>/data
MySQL
If you have used MySQL as the database for Grafana then follow the below steps
If you have installed Grafana by downloading a Debian package (.deb) then you can execute the same dpkg -i command with the new package which will upgrade your Grafana installation
Go to the download page for the latest download links
If you have installed Grafana from the APT repository, then Grafana will automatically update when you run apt-get upgrade to upgrade all system packages.
sudo apt-get update
sudo apt-get upgrade
Upgrade from binary .tar file
If you downloaded the binary .tar.gz package, then you can just download and extract the new package and overwrite all your existing files. However, this might overwrite your config changes.
It is recommended that you save your custom configuration changes in a file named <grafana_install_dir>/conf/custom.ini. This allows you to upgrade Grafana without risking losing your configuration changes.
Docker
The below snippet is an example of how to update Grafana in Docker but it depends on how you have configured your container
If you downloaded the Windows binary package you can just download a newer package and extract it to the same location (and overwrite the existing files). This might overwrite your configuration changes. It is recommended that you save your configuration changes in a file named <grafana_install_dir>/conf/custom.ini as this will make upgrades easier without risking losing your configuration changes.

5. Updating Plugins
Once we upgraded Grafana now we will update the plugins. You can update all plugins using
grafana-cli plugins update-all

6. Restart grafana-server
Now we have upgraded our Grafana to v8.0 it’s time to restart the grafana-server using the below command
sudo service grafana-server restart
Now open Grafana in your localhost with the following port number localhost:3000 where you could see the updated version of Grafana like below
