This topic describes how to start, pause, and resume a data migration project.
Start a data migration project
If you have configured a data migration project but did not start it after the precheck was passed, you can find the project in the list of migration projects and start it.
Log on to the ApsaraDB for OceanBase console.
In the left-side navigation pane, choose Data Transmission > Data Migration.
On the Data Migration page, click Start in the Actions column of the target project.
You can also click the project name on the Data Migration page to go to the details page, and click Start in the upper-right corner.
Pause a data migration project
You can pause a data migration project in the Running state. After a data migration project is paused, the data transmission service pauses the running subtasks in the orchestration task list and stops scheduling all subsequent subtasks.
Log on to the ApsaraDB for OceanBase console.
In the left-side navigation pane, choose Data Transmission > Data Migration.
On the Data Migration page, click Stop in the Actions column of the target running project.
You can also click the project name on the Data Migration page to go to the details page, and click Stop in the upper-right corner.
In the dialog box that appears, click OK.
ImportantThis operation will pause the real-time synchronization component, full verification component (if any), and full migration component (if any). The project cannot be recovered if it is paused for more than 12 hours.
Resume a data migration project
You can resume a data migration project in the Paused or Failed state. The data transmission service runs the pending subtasks in the orchestration task list in sequence.
Log on to the ApsaraDB for OceanBase console.
In the left-side navigation pane, choose Data Transmission > Data Migration.
On the Data Migration page, click Resume in the Actions column of the target project.
You can also click the project name on the Data Migration page to go to the details page, and click Resume in the upper-right corner.
