This topic describes several subsequent operations that you can perform after you create a migration job.

Subsequent operations vary with the types of migration jobs. You can manage migration jobs of different types as follows.

Manage full migration and incremental migration jobs

  • View the status of a migration job
    After you create a migration job, one of the following states is displayed for the job:
    • Migrating. This state indicates that data is being migrated. Wait until the migration job is completed.
    • Create Failed. This state indicates that the migration job failed to be created. You can view the cause of the failure and create a new migration job.
    • Completed. This state indicates that the migration job is completed. You can view the migration report.
    • Failed. This state indicates that the migration job failed. You can view the migration report and migrate the files that failed to be migrated.
  • Modify flow control settings
    During migration, you can modify flow control settings at any time based on your needs.
    1. In the Data Transport console, choose Data Online Migration > Migration Jobs. On the Migration Jobs page, find a migration job and click Manage.
    2. Click Stop and ensure that the job is stopped.
    3. On the Flow Control Time Schedule chart, click Reset.
      • To add a flow control setting, select an appropriate time range and maximum flow, and click Add.
      • To delete a flow control setting, click Delete next to the flow control setting.
      • To modify a flow control setting, you must delete the previous setting and add a new flow control setting.
    4. Click OK and click Start to restart the job.
  • View a migration report
    1. On the Migration Jobs page, find a job and click Manage.
    2. Click Generate Migration Report. After a report is generated, click Export to export the report.
      In a migration report, the following files appear in the File lists section:
      • The file whose name ends with _total_list. This file contains a list of all files that need to be migrated.
      • The file whose name ends with _completed_list. This file contains a list of files that are successfully migrated.
      • The file whose name ends with _error_list. This file contains a list of files that failed to be migrated.
    3. At the destination NAS data address, find the generated folder aliyun_mgw_import_report/. The folder includes the three files that appear in the migration report. You can download these files to view the detailed lists.
      Each list consists of four columns. The description of four columns is provided as follows:
      • For the file whose name ends with _total_list, the four columns include the source data address, name, size (measured in bytes), and last modification time of each file that needs to be migrated. The format of a source data address is nas://<the name of a mount point>:/<prefix>/<objectName>. For example, nas://0a28888892-afr82.cn-hangzhou.nas.aliyuncs.com:/myprefix/testfile.txt.
      • For the file whose name ends with _completed_list, the four columns include the name, size (measured in Bytes), CRC-64 checksum, and completion time of each migrated file.
      • For the file whose name ends with _error_list, the four columns include the name, start time, completion time, and error description of each file that failed to be migrated.
  • Retry a failed migration job

    If a migration job failed, you can view the generated file whose name ends with _error_list to identify the cause of the failure and troubleshoot the issue. On the Migration Jobs page, find the failed job, click Manage, and click Retry to remigrate the files that failed to be migrated.
