Hi @dharmesh,
Analytics VISITOR_ID is an analytics only attribute and doesn't flow into Adobe Target. What we need is a common ID that can sync the data together.
1. If your customers have unique UserID/CustomerID and can classify them based of that ID, you can pass that data into Adobe Target using Customer Attributes. (See @jacobto1's answer below).
2. Considering you have Adobe Analytics and Adobe Target, I would assume that Experience Cloud ID service is implemented on your site.(Implement the Experience Cloud Identity Service for Target | Adobe Experience Cloud Services).
If ECID service is implemented, another feasible option would be to feed the classification data back into Analytics, create a segment in Analytics and share that segment into Adobe Target through Experience Cloud (Take note on the limits).
Publish segments to the Experience Cloud | Adobe Analytics
3. Creating an "Experience Cloud Audience" is another option that may work in your case. I am not sure, but you may have to get that enabled through your Adobe Account Representative. Adobe Experience Cloud Audiences | Adobe Experience Cloud Services.
