Prepare a Huawei account, create a user, and grant permissions to the user to use DRS.

For details, see Registering a Huawei ID and Enabling Huawei Cloud Services.

Register an account by referring to Permissions Management.

Database

Prepare the source and destination databases with required account permissions.

NOTE:
  • You are advised to create an independent database account for DRS task connection to prevent task failures caused by account modification.
  • After changing the account passwords for the source and destination databases, modify the connection information in the DRS task as soon as possible to prevent automatic retry after a task failure. Automatic retry will lock the database accounts.
