Preparations
This topic describes the preparations for data migration.
Step 1: Create a destination bucket
If your destination is Alibaba Cloud OSS, you must create a destination bucket to store the migrated data. For more information, see Create buckets.
If the destination is CPFS for Lingjun, you can skip this step.
Step 2: Create a RAM user for data migration
To ensure data security, we recommend that you create a Resource Access Management (RAM) user and grant permissions to the user based on the principle of least privilege.
Log on to the Resource Access Management (RAM) console.
In the navigation pane on the left, choose .
On the Users page, click Create User.
On the Create User page, in the User Account Information section, enter the Logon Name and Display Name.
In the Access Mode section, select Console Access and Programmatic Access, and then save the generated username, password, AccessKey ID, and AccessKey secret.
Console Access: You can set a console password, require a password reset upon next logon, and enable multi-factor authentication (MFA).
Programmatic Access: Automatically generates an AccessKey pair for the RAM user to enable access through an API or other developer tools.
Step 3: Add permissions to the RAM user
After the RAM user is created, find the RAM user on the Users page and click Add Permissions in the Actions column. Attach the system policy AliyunOSSImportFullAccess to the RAM user.
