Change datasource from Analysis Services to Power BI dataset (connected to AS)

Yes.

I have PBI reports that connect to SSAS Tabular.

I made a new empty report (dataset) that connects to that same SSAS Tabular server.

I want to update all my reports to use that new dataset that I published.

I was hoping I could just change the connection in the reports or maybe edit the report file's connection string, etc....

Good suggestion on making a new and copying over, I'll test that as well.
