Hi MikBrePer​,

Build 15.0.1122.101 is an official Microsoft Power BI Report Server September 2026 update, released on 26 October 2026. Microsoft lists it as containing various bug fixes.

So if you are currently on 15.0.1122.95 and facing issues, I would recommend upgrading to 15.0.1122.101 after taking the normal Report Server backups.

Before upgrading, back up:

  • ReportServer and ReportServerTempDB
  • Report Server encryption key
  • Configuration files

Then install the newer PBIRS build and validate a few important reports, refreshes and subscriptions.

Since Microsoft has published 15.0.1122.101 as the newer supported September 2026 build, I would use this build rather than staying on .95.
