The computer system can include a program database module configured to define, at a shadow system, a shadow program database including data and a structure collectively defining an upgrade to an original program database on an original system. The computer system can include a basis module configured to define at the shadow system a shadow basis database related to start functionality of the shadow system. The computer system can also include a downtime execution module configured to trigger the shadow system to change from a downstate to an upstate based on a combination of data included in the shadow basis database and the data of the shadow program database."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Shadow system start during upgrade of an original system","description":"In one general aspect, a computer system can include instructions stored on a non-transitory computer-readable storage medium.
