how to replace a frontend report with another one with different dataset

[Jeanxyz]

I want to replace a published front-end report with another one. I have prepared the new version report with the same name as the old one. But when I load the new report to the production workspace, it's loaded as a new report with the same report name. I guess Power BI service recognizes that the new report is linked to a different back-end datamodel, hence it keeps both reports instead of replacing the old one with the new front-end report. 

I want the new report to replace the old one so that I don't need to set up the permissions from scratch. Is there a solution to the issue?
