This topic describes how to start, pause, and resume a data migration task.
Start a data migration task
If you have created a data migration task but did not start it after it passed the precheck, you can find the task in the list of migration tasks and start it.
Log in to the OceanBase Migration Service (OMS) console.
In the left-side navigation pane, click Data Migration.
On the Data Migration page, click Start in the Actions column of the target task.
You can also click the task name on the Data Migration page to go to the details page, and click Start in the upper-right corner.
Pause a migration task
You can pause a running data migration task. After a data migration task is paused, OMS pauses the running subtasks in the orchestration task list and stops scheduling all subsequent subtasks.
Log in to the OMS console.
In the left-side navigation pane, click Data Migration.
On the Data Migration page, click Pause in the Actions column of the target task.
You can also click the task name on the Data Migration page to go to the details page, and click Pause in the upper-right corner.
In the dialog box that appears, click OK.

In the left-side navigation pane, click Data Migration.
