# Updating existing content

> [!important]
> If you are upgrading from SXA 10.4 to SXA 10.5, skip this step.

After you install the SXA package, the *Experience Accelerator Content Upgrade Required* message appears.

To use the SXA upgrade tool:

1. In the message, click **Upgrade** to start the upgrade procedure.

    The **Powershell Script Results** dialog displays all the upgrade steps for your installation. Every upgrade step comes with a title, a description, and additional options (if any).

2. Click **Upgrade**.

    Before executing each upgrade step, you can decide to have a **Dry run**. A dry run tests this upgrade step and creates a log of all content changes before the upgrade script starts. To apply the changes click **Proceed**.
