Powershell script to change Datasource Test to Production

Does someone have a powershell script to change the data source?
For example I want deploy my report to powerBI reporting service from Test to Productios therefore i need to change the datasource from
OTA-DWH-01\Test to OTA-DWH-02\Production
I have a lot of reports so doing it manually will take a lot of time. I now have to open each report indivually and change the datasource.
