Power BI Report Server Upgrade

Hi jijianish​,

Thanks for reaching out to the Microsoft Fabric Community forum.

Yes, Power BI Report Server supports an upgrade process. Before upgrading, Microsoft recommends backing up the encryption keys, report server databases, and configuration files.

To upgrade, run PowerBIReportServer.exe, select Upgrade Power BI Report Server, accept the license terms, and select Upgrade.

After the upgrade, make sure report authors use the version of Power BI Desktop for Power BI Report Server that matches the upgraded server.

For the detailed upgrade steps, please refer to the official documentation:

I hope this helps. Please feel free to reach out if you have any further questions.
Thank you.
