Abstract: A physio-logical migration of a database from a source system to a target system may include exporting a catalog of the database in a data interchange format that preserves the hierarchical dependencies present amongst the entities included in the catalog. The physio-logical migration of the database may further include exporting the contents of a table in the database in a binary format compatible at the target system. The binary format may be a data buffer having a metadata portion, a fixed-size portion, and a page chain portion. Where the target system is a cloud-based system, the physio-logical migration of the database may include exporting the catalog and the contents of the table to a cloud-based object store before importing the catalog and the contents of the table to the target system. Related systems and articles of manufacture, including computer program products, are also provided.

Abstract: Technologies are described for migrating deployment infrastructure containers. Deployment infrastructure containers are used for isolating and deploying related database objects together. Deployment infrastructure containers can store design-time artifacts and run-time artifacts. Deployment infrastructure containers can be migrated using a first migration technique in which catalog objects are migrated from a source database system to a target database system and updated to work in the target database system (e.g., by updating metadata). Deployment infrastructure containers can also be migrated using a second migration technique that migrates design-time artifacts and builds the design-time artifacts at the target database system to re-create the run-time artifacts. Migrated deployment infrastructure containers can be integrated into the target environment, which can include creating new service instances and associating them with the migrated deployment infrastructure containers.
