Report server on virtual machine - upgrade version
We are currently planning to upgrade our on-premises Power BI Report Server environment running on a Virtual Machine (VM). However, we are encountering intermittent failures during the upgrade process, which is blocking our deployment.
Since this is a production environment hosting more than 1000 reports, we cannot proceed with the upgrade until we ensure absolute stability and identify the root cause of these issues.
Problem Details & Symptoms:
- Intermittent Upgrade Failures: The upgrade process behaves inconsistently; it succeeds in some trial environments but fails randomly in others.
- Initial SSL Certificate Warnings: In the early stages of the upgrade attempt, the installer threw errors regarding the SSL certificate validation.
- Analysis Services Connectivity Issues: Upon examining the Power BI Report Server log files (PBIRS\LogFiles), we detected frequent connection timeout and authentication errors pointing to the underlying Analysis Services (SSAS) instance during/after the upgrade sequence.
Due to the scale of our deployment (1000+ reports) and the corporate criticality of this server, we urgently request your technical assistance to review our environment and log files.
Environment Details:
- Hosting Environment: Windows Server Virtual Machine (VM)
- Current PBIRS Version: Jan 26
- Target PBIRS Version: May 26
- Database Backend: SQL Server / SSAS
Also , I could not find Microsoft’s official support ticket website. Could you please help any of these above?
Thanks.
Hi gkc9
The issue likely stems from a combination of SSL certificate validation and SSAS connectivity (Kerberos/SPN or network latency). I recommend validating TLS/certificates, testing SSAS connectivity from the PBIRS VM, and reviewing PBIRS logs for authentication/timeouts.For production environments, Microsoft recommends a side-by-side migration approach instead of in-place due to stability risks.- Build a new VM with May 2026 PBIRS
- Restore ReportServer databases
- Reconfigure URLs, certificates, SSAS connections
- Validate reports
- Switch DNS/traffic
This eliminates risk of upgrade corruption.You can raise a support ticket via Microsoft 365 Admin Center -> Support if logs indicate persistent failures.also you can raise an official support ticket through this- https://learn.microsoft.com/power-bi/support/If this reply helped you please mark it as a solution.Thank yousunita
