    E-MapReduce:Legacy EMR Data Platform migration

    Last Updated:Aug 26, 2026

    As of 21:00 on February 21, 2022 (UTC+8), the EMR Data Platform no longer receives updates and is in maintenance-only state. If you still use the data development features in the old console, migrate to EMR Workflow as soon as possible.

    EMR Workflow is a fully managed workflow and task scheduling service, fully compatible with open source Apache DolphinScheduler. Capabilities include:

    • Open source compatibility -- fully compatible with open source Apache DolphinScheduler

    • Visual workflow management -- build and manage workflows through a drag-and-drop interface

    • Production scheduling -- stable task execution backed by managed infrastructure

    • Data warehouse development -- streamlined workflow creation and scheduling for building data warehouses

    For more information about EMR Workflow, see What is EMR Workflow?

    If you want to migrate from EMR Data Platform to DataWorks, see End of Updates for EMR Data Platform.

    Migration process

    EMR Workflow lets you export workflows and tasks from the legacy EMR Data Platform as an Apache DolphinScheduler-compatible JSON file, and then import the file to quickly and cost-effectively migrate your workflows and tasks.
