Abstract

The disclosure generally describes methods, software, and systems for completing near-zero downtime system upgrades. A new access schema for a new version of a system is created and stored. The system uses an existing access schema corresponding to a current version of the system. For the new version of the system, a shadow client is created that includes customizations and read-only views to master data and application data. Projection views into the new access schema are created from the shadow client. Using the new access schema and the shadow client, customization changes to the master and application data are automatically performed and stored at the shadow client. Upon receiving a request to switch to the new version of the system, the virtual transport is imported to a shadow-phase of the production client. The production client is switched to begin using the new access schema.
