2. Choose Data Online Migration > Migration Jobs. On the File Sync Management page, find the migration job for which you want to modify the throttling settings and click Manage in the Operation column.
3. Click Stop and verify that the job is stopped.
4. On the Flow Control Time Schedule chart, click Reset.
   • To add a throttling setting, select an appropriate time range and maximum flow and then click Add.
   • To delete a throttling setting, click the icon next to the throttling setting.
   • To modify a throttling setting, delete the current setting and then add a new throttling setting.
5. Click Submit and then click Start to rerun the migration job.

View a migration report

1. On the migration job list, find the migration job and click Manage.
2. Click Generate Migration Report. After a report is generated, click Export to export the migration report.
   In a migration report, the following files appear in the File Lists section:

   • The file whose name ends with _total_list. This file lists all files to be migrated.
   • The file whose name ends with _completed_list. This file lists the files that are migrated.
   • The file whose name ends with _error_list. This file lists the files that fail to be migrated.
3. In the Object Storage Service (OSS) console, find the automatically generated folder aliyun_mgw_import_report/. The folder includes the three files that appear in the migration report. You can download these files and view the detailed list that is included in each file. We recommend that you use the ossbrowser tool to view these files.
   Each list consists of the following columns:

   • The columns of the file whose name ends with _total_list include the source data address, file name, and version ID. The columns also display whether the job version is the latest at the source data address and whether the job version is deleted at the source data address. The last two columns display the file size measured in bytes and the time when the file was last modified. The format of a source data address is <vendor>://<bucketName>/<prefix>/<objectName>. The following string provides an example: oss://bucket-test1022/myprefix/testfile.txt.
     Note

     • Version ID: the version ID of the file at the source data address.
     • Latest at the source data address: indicates whether the current version is the latest version of the file at the source data address. Valid values: true and false.
     • Deleted at the source data address: indicates whether the current version is deleted at the source data address. Valid values: true and false.
   • The columns of the file whose name ends with _completed_list include the file name and the file size measured in bytes. The last two columns display the CRC-64 checksum and whether the migration is skipped.
     Note Skip migration: indicates whether the file that has the same name at the source and the destination data addresses is skipped during migration. Valid values: 1 and 0. A value of 1 indicates that the file is skipped during migration. A value of 0 indicates that the file is not skipped during migration. The value of this field depends on the value of the File Overwrite Method parameter that you specify when you create the migration job.
   • The columns of the file whose name ends with _error_list include the file name, the time when the migration job starts, the time when the migration job stops, and the error description. The last column indicates whether the migration is skipped.

Rerun a failed migration job

If a migration job fails, you can check the generated file whose name ends with _error_list to identify the cause of the failure and resolve the issue. On the File Sync Management page, find the failed migration job, click Manage in the Operation column, and click Retry to migrate the failed files.
