Migration Assistant
Migration Assistant migrates data objects across DataWorks versions, Alibaba Cloud accounts, regions, and workspaces.
You can export auto triggered nodes, manually triggered nodes, resources, functions, data sources, table metadata, ad hoc queries, and script templates. DataWorks supports full, incremental, and custom export tasks.
Limits
-
Only old-version data development tasks can be imported or exported.
-
Migration Assistant does not support data quality monitoring nodes, node groups, and data push nodes in old-version DataStudio.
-
All DataWorks editions support migrating tasks from open source scheduling engines such as Oozie, Azkaban, and Airflow to the cloud. Migration policies vary by edition:
DataWorks migration feature
Basic Edition
Standard Edition
Professional Edition
Enterprise Edition
Number of DataWorks export packages supported per tenant
Note-
When you create an export task and the export succeeds, an export package is generated.
-
If the number of export packages exceeds the edition limit, you can only obtain more export packages by upgrading your edition. You cannot purchase additional export packages.

Creating export or import tasks requires an Alibaba Cloud account or the workspace administrator role. RAM users without this role can only view tasks.
Precautions
-
Migration Assistant does not migrate data. Use batch synchronization instead. For more information, see Overview of batch synchronization.
-
Migration Assistant requires a Google Chrome version later than v69 on PCs.
Scenarios
-
Back up node code
Back up node code to prevent accidental deletion. Create a full export task.
-
Export a common workflow for replication
Export a reusable workflow to replicate in other workspaces. Create a custom export task.
-
Build a test environment
Copy all node code and replace production data with test data. Create a full or custom export task.
-
Develop data in a hybrid cloud environment
Migrate node code from Alibaba Cloud public cloud to Alibaba Cloud Apsara Stack for hybrid cloud development. Create a custom export task.
-
Migrate data objects between the development and production environments
When the production and development environments are fully isolated, export nodes from development and import them to production for deployment.
