Integrating preview systems for early validation and maintenance in development-to-production landscapes provisioned by continuous delivery

Abstract:

A development maintenance (Dev-Maintain) computing system is upgraded from a release version n to a release version n+1, where a production (Prod) computing system is on the release version n, and a development preview (Dev-Preview) computing system is on the release version n+1. Changes are transported from the Dev-Preview computing system to the Dev-Maintain computing system. Inactive changes transported from the Dev-Preview computing system into the Dev-Maintain computing system are merged to generate merged changes. The merged changes are transported to the Dev-Preview computing system. A release version upgrade is performed to the Prod computing system and to the Dev-Preview computing system. Active changes are transported from the Dev-Maintain computing system to the Prod computing system.
