    Abstract: A distributed database service can be migrated from a source environment to a destination environment. The distributed database service can be associated with a database and database members. the source environment can include source database members such that each source database member includes a respective image of the database. Migrating the distributed database service can include provisioning a migration gateway in the source environment. Migrating the distributed database service can also include provisioning a domain name system service in the destination environment. Migrating the distributed database service can also include provisioning a first destination database member in the destination environment. While updating the first destination database member with a respective image of the database, the distributed database service can process a database request.

    Abstract: Disclosed herein are system, method, and computer program product embodiments for synchronizing data in a source system to an application without relying on middleware. An embodiment operates by performing an initial load of records for an object for an application from a source system, thereby retrieving a first set of records. The embodiment first maps the first set of records to the object using a transform template. The embodiment creates the object in the application using the first set of records based on the first mapping. The embodiment performs a delta load of records for the object from the source system, thereby retrieving a second set of records. The embodiment second maps the second set of records to the object using the transform template. The embodiment then updates the object using the second set of records based on the second mapping.
