Abstract: Embodiments herein relate to replacing a legacy Pick environment with a modern microservice architecture. A legacy database and a modern database may be operated in parallel for data validation. During the validation process, the legacy database may be used as the master copy of the data. After verifying that the modern database satisfies the data needs of a system, the system can switch to using the new modern database as the master copy.

Abstract: Embodiments herein relate to managing a distributed system with various local configurations using one or more centralized configurations. A central configuration system may store one or more centralized configurations for a set of applications. Updates to the centralized configurations may be transmitted to one or more of a plurality of local systems. The plurality of local systems may execute one or more of the set of applications. Each application may be associated with a local application configuration specific to a local system on which the application is executed. The local systems may determine whether the updates to the centralized configurations apply to the local application configuration for the one or more local applications stored on the memory, and update the local application configuration when the updates are applicable.

Abstract: Embodiments herein relate to replacing a legacy Pick environment with a modern microservice architecture. A legacy database and a modern database may be operated in parallel for data validation. Part of the data validation may include scanning the legacy database for updates to items stored thereon. Embodiments herein may generate an update message by combining item keys from across the multiple files that correspond with a same business object.
