Abstract
Revocation of a zero downtime upgrade of an upgrade procedure of a source system to a target system is initiated. Thereafter, upgrade activities are stopped at the target system and production activities are stopped at the source system. At least a portion of the target tables can be subsequently dropped and any associated table structure changes can be revoked. At least a portion of the target tables are then switched from use by the target system to use by the source system. Next, the source system is connected to the source database schema to enable use of the source system in its state prior to the initiation of the upgrade procedure. Related apparatus, systems, techniques and articles are also described.
