:Migrate task flows to the new version of task orchestration

Usage notes

• If you do not have task flows that were developed in the old version of task orchestration, you are not affected after the old version is brought offline, and you do not need to perform the operations described in this topic.
• You can migrate each task flow only once. After a task flow is migrated, we recommend that you do not modify the task flow in the old version of task orchestration because the task flow cannot be migrated again and the modifications that you make cannot be synchronized to the corresponding task flow in the new version.
  Note If you want to modify a task flow after it is migrated, modify it in the new version of task orchestration.

Procedure

1. Go to the DMS console V5.0.
2. In the top navigation bar, click DTS. In the left-side navigation pane, choose Data Development > Task Orchestration(Old).
3. Open the dialog box for the quick migration feature.
   • On the Task Orchestration(Old) page, click Quick Migration.
   • Alternatively, click the icon in the left-side pane of the Task Orchestration(Old) page. In the list that appears, click the icon.
4. In the Quick Migration dialog box, set the parameters that are described in the following table and click Migrate.
   Note If you have any questions when you use the quick migration feature to migrate task flows, you can move the pointer over Online Consultation in the upper-right corner of the Quick Migration dialog box and scan the QR code to join the DingTalk group for assistance.

   Parameter	Description
   Migration Level	Selected Task Flows: migrates the selected task flows to the new version of task orchestration. Note You must be the owner of the selected task flows. All Task Flows of Tenant: migrates all the task flows within the current tenant to the new version of task orchestration. Note To select this option, you must be a DMS administrator. DMS automatically skips the task flows that have been migrated.
   Migration Option	Migrate Task Flows and Data: migrates the nodes and configurations of the specified task flows to the new version of task orchestration. This option is selected by default and cannot be unselected. Note The execution records of task flows are not migrated. Automatically Unpublish and Publish: publishes the task flow versions that were last published in the old version of task orchestration to the new version of task orchestration for the specified task flows and unpublishes the task flows from the old version of task orchestration. Note We recommend that you select this option for a task flow when the task flow is not scheduled to be executed. For task flows that have not been published, DMS does not automatically publish the task flows to the new version of task orchestration or unpublish them from the old version of task orchestration even if you select this option.
   Task Flow Selection	If you set the Migration Level parameter to Selected Task Flows, you must select the task flows that you want to migrate. In the Task Flows to Be Migrated section, select one or more task flows that you want to migrate. Click the icon to add the selected task flows to the Selected Task Flows section.

5. In the Confirm Migration message, confirm the migration configurations and click OK.
   If the Successful Migration message appears in the upper part of the page, task flow migration is successful.

   After you migrate a task flow, the data of the task flow in the old version of task orchestration remains unchanged, but the task flow is marked in the task flow list. The following list describes the two scenarios involved:

   • If only Migrate Task Flows and Data is selected for the Migration Option parameter when you migrate the task flow, the task flow is marked by the icon in the task flow list after migration.
   • If Migrate Task Flows and Data and Automatically Unpublish and Publish are both selected for the Migration Option parameter when you migrate the task flow, the task flow is marked by the icon in the task flow list after migration.

   

   Note After a task flow is migrated, we recommend that you do not modify the task flow in the old version of task orchestration because the task flow cannot be migrated again and the modifications that you make cannot be synchronized to the corresponding task flow in the new version.
6. Optional: View and modify migrated task flows in the new version of task orchestration.
   1. In the top navigation bar, choose DTS > Data Development > Task Orchestration.
   2. On the page that appears, search for and find a migrated task flow in the task flow list and click the task flow name.
      Note If the name of a task flow to be migrated is the same as that of an existing task flow in the new version of task orchestration, the name of the migrated task flow is suffixed with _old.
   3. On the details tab of the task flow, view and modify the task flow as required.
      • Task flows that are migrated from the old version of task orchestration are marked by the icon in the task flow list.
      • For a migrated task flow that has been published in the old version of task orchestration, if Automatically Unpublish and Publish is selected for the Migration Option parameter when you migrated the task flow, the Release Status parameter is displayed as Published in the upper-right corner of the details tab.
