I have added new web property on same website which had one web property before.
I have removed the embed code of first web property from all web pages.
and added the embed code of new web property.
Configured the new report suites and added new tools in the new web property.
Still I am seeing the old web property report suite ID on all web page when I checked using Adobe Debugger, even after disabling the web property.
(I have tried all browsers and cleared all caches of browsers)
how do I completely disable earlier implementation of Web property and add new one ?
This does not sound possible... your page must either still have the old web property's DTM Header tag, or else your new web property's configuration uses the same report suite id.
