<p class="callout warning">Backup and Re-Deploy the Stack</p>

VaultWarden has been optimized for [running in Docker](https://github.com/dani-garcia/vaultwarden/wiki/Updating-the-vaultwarden-image). This allows you to [re-deploy the stack through Portainer](https://hub.subspace.services/books/portainer/page/updating-a-stack "Updating a Stack") to download the latest updates.

Due to the important nature of this data, it is always crucial to perform a full backup before upgrading.
