Preparing for Migration
Preparing for Migration
Updated on 2025-01-08 GMT+08:00
Before using OMS to migrate data, make preparations by referring to this section.
Registering a HUAWEI ID
Creating Access Keys for the Source and Destination Accounts and Obtaining the Required Permissions
- Source (Google Cloud):
Perform the following steps to generate a key file and grant the basic Viewer role to your Google Cloud account.
- Log in to the Google Cloud console using your source account.
- On the console, select the project that your service account belongs to. Choose IAM & Admin > Service Accounts.
- On the Service accounts page, click CREATE SERVICE ACCOUNT. Enter the basic information about the account, such as the name and description.
- Choose Quick access > Basic > Viewer to assign the basic Viewer role to the service account.
- Create a key for the account. Select the key type you want, for example, JSON. Click CREATE to download a service account key file to your computer.
- Keep the downloaded key file secure. The file contains the credentials used for accessing Google Cloud.
- 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.
