Systems, methods, and apparatuses can present optimized data migration. Embodiments can provide improved data migration processes using a data migration assistant that executes on a source system to facilitate the migration of documents and data to a destination system. The migration assistant can communicate with a migration controller server to authenticate and identify the migration assistant and migration project that the migration assistant is to be used for. The migration controller server can use the identifier to determine commands corresponding to the migration project to send to the migration assistant to collect data and make changes to the source system.
