I don't think Microsoft actually support an inplace upgrade of SSRS to PBI Report Server see here https://docs.microsoft.com/en-us/power-bi/report-server/migrate-report-server
The documentation talks about cloning the ReportServer database, but I think you are meant to let the PBI Report Server config manager create a new ReportServerTempDB database.
