Hi @vijayc88216288 !
Reports once passed to Analytics server cannot be deleted or modified. So I suggest
1. View the activity reports in analytics workspace from the day it was activated > You should be able to see both the experience names
Only new experience will display as all the new visitors are not qualifying for this new name 🙂
2. You would need to add the visitor of both the experiences to have the complete view of reports.
Hope that helps!
