A partner agency is transitioning our client to Display and Video 360 from Google Display Network, and have asked me to implement a DV360 tag via Tealium iQ. I haven't been able to find any info regarding this and it seems the DV360 data is fueled by current Floodlight and Remarketing tags that are already implemented on the site via Tealium iQ. I did come across an article on Google to remove old tags and implement a Global tag for DV360. I dont have access to their DV360 account so not sure if there is gtag i need to leverage for the implementation. 

Are there any implementation requirements for DV360 I need to make or will the current tags still pass the required data to DV360?
