ASK BOSCO® seamlessly integrates data from Universal Analytics (UA) and GA4 by setting a specific transition date, such as July 1, 2023, as the default. Data before this date is attributed to UA, while data after it is attributed to GA4. This approach ensures continuity in your channel reports, making them appear seamless despite the change in data sources. You also have the flexibility to define your own transition date to suit your needs.
