Hello, We recently updated our domain and are attempting to keep tracking across both domains. Using this older thread: https://nation.marketo.com/t5/Product-Discussions/Munchkin-Tracking-Multiple-Sites/td-p/132194 and the postMessage API I have been able to set up cross domain cookie tracking, however I am a bit stuck on the next steps. I see "_mkto_trk" and am wondering if this is the correct key to target, and if so, what is the recommended practice for doing this. It looks like if a visitor hasn't opted into any material (filled out form) marketo still assigns a value to this cookie. Would it make sense to see if "old domain cookie value exists" and then extract that value and replace "new domain cookie value" with the old one? Will this allow for leads to be tracked across domains? Thanks in advance
