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

Home Assistant has been optimized for running in Docker. 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.

Integrations within your Home Assistant, especially those from the [community store](https://www.hacs.xyz/), may encounter issues with newer updates. It is always a good idea to have a backup to downgrade your installation in case of errors.
