Migrating a bank from OpenShift 3 to OpenShift 4
A bank’s digital channels ran on OpenShift 3, past its end of life. We moved production to OpenShift 4 inside one short change window, rebuilt disaster recovery across two sites, then ran the platform and its DevSecOps toolchain around the clock.

Production moves from OpenShift 3, past its end of life, to OpenShift 4 at the primary site. A second cluster at the DR site receives continuous replication. Afterwards the platform is run 24x7 across production, DR and non-production.
