    Unfortunately, historical data prior to connecting Google Analytics 4 (GA4) to BigQuery is not automatically available. BigQuery only starts collecting data from the point you set up the connection between both platforms. This means any historical data that existed before the connection was established will not be mirrored automatically in BigQuery. Unfortunately, as of now, Google does not provide an option to migrate or backfill historical data from GA4 to BigQuery. In order to have a more comprehensive set of historical data in BigQuery moving forward, you’ll want to ensure that all data generating sources are properly hooked up to GA4, so as to have them streamed to BigQuery in real-time.
