## 🐞 Bug Fixes

## ⚙️ Install and Upgrade

* [Fresh install](/get-started/self-host/deploy-with-docker)

* [Upgrade](/get-started/self-host/upgrade)

*Before upgrading: 1) Back up the [metadata](https://www.bytebase.com/docs/administration/back-up-restore-metadata/) — in-place downgrade is not supported. 2) Do not run multiple containers on the same data directory. 3) Terraform users: upgrade Bytebase server first, then apply the new Terraform config.*
