Hi hgupta13, the thing is: - you cannot republish the report with changed data source without rebinding it with API first in the report, as you will encounter with an error. - however after rebinding it, you are no longer able to download .pbix file to desktop. To do so, you have to republish the the original .pbix file with new data source. I created a Python tool, where you put all IDs(report id, group id, new datased id) in csv file (unlimited count of reports) and it rebinds all at once. Ping me a PM and I can provide you that.
