Upgrade procedure in which a shadow system is set up with the target release, while the original system is still running with the source release in the same database
The shadow system consists of the SAP NetWeaver Application Server tables (or SAP Web Application Server tables or SAP Basis tables in older releases) and parts of the repository of the original system. Some of the upgrade actions are performed in the shadow system during production operation, which reduces downtime during the upgrade.
