Preparing for Migration

Before you use OMS, make preparations by referring to this section.

Registering a HUAWEI ID

Register a HUAWEI ID and enable Huawei Cloud services.

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 (Alibaba Cloud): Check whether you have created an access key for and assigned the AliyunOSSReadOnlyAccess permission to your Alibaba Cloud account. If you have not, perform the following procedures:
    1. Log in to the RAM console using your Alibaba Cloud account.
    2. In the navigation pane on the left, choose Identities > Users.
    3. On the Users tab page, click Create User.
    4. On the Create User page, in the User Access Key area, click Create Access Key.
    5. Assign required permissions to the user.

      Locate the RAM user, and click Add Permissions in the Actions column. Assign the user the AliyunOSSReadOnlyAccess permission.

  • Destination (Huawei Cloud): 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. Alibaba Cloud OSS provides the ossutil tool to restore archive objects with specified prefixes. For details, see Restoring Archive Data on Alibaba Cloud OSS.

Perform the migration after all archive data is restored. Any data not restored will fail to be migrated.
