Abstract: This disclosure relates to method and system for legacy network transformation. The method includes receiving data corresponding to a legacy WAN from one or more data sources. Further, the method includes analyzing the data to identify one or more transformation requirements for the legacy WAN, based on one of a statistical technique, or a machine learning technique. Further, the method includes determining one or more configuration parameters corresponding to the legacy WAN based on a set of pre-defined business policy rules and the one or more transformation requirements. Further, the method includes generating a high-level design for SD-WAN based on the one or more transformation requirements and the one or more configuration parameters. Further, the method includes generating a low-level design including configuration guidelines templates for the SD-WAN based on the high-level design. Each configuration guidelines template may facilitate the transformation of legacy WAN to the SD-WAN.

Abstract: Systems and techniques for deleting master data. In one implementation, a method includes identifying a version of a collection of master data to be deleted, publishing at least a portion of the version of the collection of master data from the client data processing system to a server in the data processing system landscape, deleting the version of the collection of master data from the client data, and ending management of the deleted version at the client. The version of the collection of master data to be deleted is stored by a client in a data processing system landscape that can manage multiple versions of the collection in the data processing system landscape.
