Preparations

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

Signing Up for a Huawei Cloud Account

Sign up for a Huawei Cloud account and complete real-name authentication. If you have already signed up for a Huawei Cloud account and completed real-name authentication, skip this step.
  1. Visit Huawei Cloud and click Sign Up.
  2. Sign up for a Huawei Cloud account.
  3. (Optional) Complete real-name authentication. Real-name authentication is the process of submitting valid identity information (such as a passport or business license) for verification when you use cloud services offered in the Chinese mainland. There are individual real-name authentication and enterprise real-name authentication.

    Real-name authentication is required to use cloud services in the Chinese mainland to comply with local laws and regulations and to protect your account security and rights. Without completing real-name authentication, you cannot purchase these cloud services. For more information, see Real-Name Authentication Overview.

    To complete real-name authentication, refer to:

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

  • Source (Tencent Cloud): Check whether you have created an access key for and assigned the ReadOnlyAccess permission to your Tencent Cloud account. If not, perform the following procedures:
    1. Log in to the Tencent Cloud management console.
    2. In the left navigation pane, choose User > User List.
    3. Click a user to go to the user details page.
    4. Click the API Key tab and click Create Key to generate a SecretId and SecretKey.
    5. Assign required permissions to the user.

      On the user list page, click Grant Permission in the Operation column of the subuser, select ReadOnlyAccess, and click OK.

  • Destination: Create an AK/SK pair and assign it the required permissions by referring to Where Can I Obtain Access Keys (AK and 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 Archived 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.

You can use the Tencent Cloud console or the coscmd tool to restore archived data. For details, see Restoring Archived Data in Tencent Cloud COS.

Perform the migration after all archived data is restored. Any unrestored data will fail to be migrated.
