Hi @Kumar_Saurabh_  thanks for the response. without adding any service to the newly created datastream, how/where the property ID referencing will sit? As, right now we are referencing at_property ID as part of adobe Target service in the existing data stream.

Implemented cross domain tracking based on this documentation appendVisitorIDsTo (Cross-Domain Tracking) | Adobe Experience Cloud Services Interesting, what's the best way to check the whether visits counted separately for Domain A to Domain B. just FYI - we are running our campaign only on  website...

@Jennifer_Dungan thanks for the response. No changes in the processing of data. The only update that we did during those time period is related to cross domain tracking. we are just check if url contains query param then captures those values in v0(s.campaign)
