Preparations

Before using OMS to migrate data between OBS buckets, make preparations by referring to this section.

Registering a HUAWEI ID

Real-name authentication is required for migrations to regions within the Chinese mainland.

Creating Access Keys for the Source and Destination Accounts and Obtaining the Required Permissions

Source: Check whether the source account has an AK/SK pair and the permissions to list buckets, obtain bucket locations, list objects, obtain object metadata, and obtain object content. If it does not have, create an AK/SK pair and assign it the required permissions by referring to Creating an Access Key (AK/SK) and Obtaining Permissions for the Source Account.
Destination: Create an AK/SK pair for the destination account and obtain the required permissions. For more information, see Creating an Access Key (AK/SK) and Destination Permissions.

Creating a Destination OBS Bucket

Create an OBS bucket for storing the migrated data. For details, see Creating a Bucket.

Restoring Archive Data in the Source Bucket

You need to restore data of the Archive storage class before you migrate it. Otherwise, the migration will take a long time. For details, see Restoring Objects from OBS Archive.
