Start and stop migration tasks
You can select multiple migration tasks that are created by using Data Transmission Service (DTS) to batch start or stop the tasks. If no DTS instance is purchased for a task, a dialog box appears. You can select the required instance type from the drop-down list in the dialog box to automatically purchase and start a DTS instance.
Block migration tasks
You can block unnecessary migration tasks that interfere with the status of resources. After the tasks are blocked, they still appear in the task list, but the status of resources is no longer affected.
Delete migration tasks
You can delete unnecessary migration tasks. After the tasks are deleted, they no longer appear in the task list.
Add migration tasks to a throttling scheduling group
You can add DTS migration tasks to an existing scheduling group. This way, Cloud Migration Hub dynamically adjusts the transmission rate of the tasks based on the configurations of the scheduling group.

Define table mappings
After you add migration configurations, click Object definitions in the Operation column to define table mappings. For more information, see Objects of DTS tasks.
You can use one of the following methods to define table mappings:
1. In the Batch Configuration Template sheet of the configuration template, define table mappings.
2. In the Table Mapping Template sheet of the configuration template, define table mappings.
You can define table mappings in the Batch Configuration Template or Table Mapping Template sheet. If you define table mappings in both sheets, the settings on the Table Mapping Template sheet are used.
3. Click Download Excel Template to download the table mapping template. Open the template. Find a parameter, click the upper-right corner of the cell to view the description of the parameter, and then configure the parameter based on the description. Next, upload the template. The defined table mappings are automatically added to the Table Mapping Definition Information section.
4. Click Edit to manually define table mappings.
Make sure that table mappings are provided for all migration configurations. Otherwise, you cannot proceed to the next step.
Add migration configurations by using a template
After you click the Download Template icon in the upper-right corner of the panel, configure the parameters in the EXCEL template that is downloaded. After you configure the parameters, click the Upload migration configuration icon in the upper-right corner to upload the template. Cloud Migration Hub automatically loads the migration configurations that you specify in the template.
To specify migration configurations in the Batch Configuration Template sheet of the template, you can find a parameter, click the upper-right corner of the cell to view the description of the parameter, and then configure the parameter based on the description. You can also switch to the Table Mapping Template sheet to configure parameters.
For more information about the parameters in the template, see Parameters for batch assistant.
