Upgrading Grafana
升級Grafana
We recommend everyone to upgrade Grafana often to stay up to date with the latest fixes and enhancements. In order make this a reality Grafana upgrades are backward compatible and the upgrade process is simple & quick.
我們建議每個人都經常升級Grafana以了解最新的修補程序和增強功能。 為了實現這一目標，Grafana升級是向后兼容的，升級過程簡單快捷。
Upgrading is generally always safe (between many minor and one major version) and dashboards and graphs will look the same. There can be minor breaking changes in some edge cases which are usually outlined in the
Release Notes
and
Changelog
升級通常是安全的（在許多次要版本和主要版本之間），儀表板和圖表看起來是一樣的。 在發行說明和更新日志中通常列出的某些邊緣情況中可能會發生輕微的中斷更改
Database Backup
數據庫備份
Before upgrading it can be a good idea to backup your Grafana database. This will ensure that you can always rollback to your previous version. During startup, Grafana will automatically migrate the database schema (if there are changes or new tables). Sometimes this can cause issues if you later want to downgrade.
在升級之前，最好備份Grafana數據庫。 這將確保可以回滾到以前的版本。 在啟動過程中，Grafana會自動遷移數據庫模式（如果有更改或新表格）。 如果您稍后想要降級，有時會導致問題。
mysql
backup: > mysqldump -u root -p[root_password] [grafana] > grafana_backup.sql restore: > mysql -u root -p grafana < grafana_backup.sql
