+1. Back up your installation{% if page.installation == "os" or page.installation == "supervised" %}, using the [backup functionality](/common-tasks/general/#backups) Home Assistant offers{% endif %}.
 2. Check the release notes for backward-incompatible changes on [Home Assistant release notes](/blog/categories/core/). Be sure to check all release notes between the version you are running and the one you are upgrading to. Use the search function in your browser (`CTRL + f` / `CMD + f`) and search for **Backward-incompatible changes**.
 {% if page.installation == "os" or page.installation == "supervised" %}
 3. Select **Create backup before updating** in case you encounter an issue that requires a rollback.

-Encryption is a method of converting data into a coded format so that it can only be read by someone who has the decryption key. This ensures that your data about your home remains private. So even if someone else had a copy of your Home Assistant backup, it is unreadable for them without the decryption key.

 ## Changing your encryption key
 
-When you set up your backups, an encryption key is generated automatically. This key is used for all your backups. You can replace this key with a new one, which will be used for all future backups. To decrypt backups created before the change, you will still need the previous encryption key.
