Google GCP cloud data infrastructure. Google gcp CloudSQL database does not support the in-place upgrade or uninterrupted upgrades from MySQL release 5.6 to MySQL release 5.7. The challenge was to upgrade overflow databases live with no interruption in service - in order to upgrade the databases multi-day outage was required. All operations databases were upgraded live with no service interruption details are in this article on LinkedIn https://www.linkedin.com/pulse/doing-impossible-migrating-gcp-cloudsql-live-from-56-a-alexander/ Reporting/dw platform BG, Kafka< CloudSQL
