No. Reports created with a newer Power BI Report Server version (January 2026) are not guaranteed to be compatible with an older server version (January 2025).
Power BI Report Server and its matching “Power BI Desktop (optimized for Power BI Report Server)” are designed to work in sync by release. The recommended practice is:
- Use the Desktop version that matches the client’s server version when authoring reports.
- Or upgrade the client’s Power BI Report Server to the same (or later) release as the authoring environment.
Creating reports with the January 2026 Desktop/Server and then trying to open or host them on a January 2025 server can lead to errors or unsupported features, because features and schema changes are rolled up by release and are not backward compatible.
