    Tencent COS

    • Restore data in the source bucket
      Before you create a migration job to migrate data of the Archive and Cold Archive storage classes, you must manually restore the data. Data Online Migration does not restore data in archived files at the source data address during data migration. The files that are not restored or are being restored cannot be migrated. For more information about how to restore data of the Archive and Cold Archive storage classes, see Solutions to migrate archived data.
      Note
      • Before you create a source data address and a migration job, make sure that data in archived files is restored.
      • The duration required to restore data of the Archive and Cold Archive storage classes is based on the amount of data. Make sure that you specify an appropriate value for the restoration duration. This can prevent data from entering the archived state during migration.
      • You may be charged for the restoration operation. For information about the billing methods, contact the service provider that offers the source bucket.
    • Create a cloud API key that is used to migrate data.

      Log on to the Tencent Cloud Management Console, and choose Products > Access Key or choose Products > Cloud Access Management > Access Key > API Keys to view or create API keys.
