I have a latest version of PBI Desktop at home. I have created a PBIX report file and tried to open at where I have Report server with older version. Initially iy gave me an error message, but eventually did open it. After opening it in Report server, I "saved as" pbix file on work computer. When I tried to upload on server folder for sharing, it gave me an error that "We're not able to upload this report. The report was created with a recent version of Power Bi Desktop that is not yest supported by this server". See the screen shot attached.
At work, I can not upgrade Report Server tot he newer version. Can I "save as" my PBIX file at home to older version, and then open it into Report server at work? I could not find any info on this. Can some body please help me?
