Patent number: 11829337Abstract: Methods, systems, and computer-readable storage media for executing a first application on a source system during production use of the source system, providing a second application on a target system, during the production use of the source system: migrating data from the source system to the target system based on a catalog delta, and a data delta, each of the catalog delta, and the data delta being periodically determined, and determining whether a completion time exceeds a threshold time, the completion time being determined based on a last-determined data delta, and, in response to determining that the completion time does not exceed the threshold time: halting production use of the source system, and completing migration to the target system based on the last-determined data delta.Type: GrantFiled: November 16, 2016Date of Patent: November 28, 2023Assignee: SAP SEInventors: Saskia Kurz, Alexander Schroeder, Thomas Loetzer, Marco Paskamp, Kerstin Welk, Martin Fei, Enno Folkerts, Christoph Bautz, Tilo Heinrich
