Moving Huawei Cloud ECSs from Multiple Accounts to a Single Account

Overview

Server Migration Service (SMS) can help you easily move Elastic Cloud Servers (ECSs) from multiple Huawei Cloud accounts to a single Huawei Cloud account, regardless of whether these ECSs are in the same region or in different regions.

Procedure

1. Obtain an AK/SK pair for the account you are migrating to. For details, see How Do I Create an AK/SK Pair for an Account?

   If you are migrating to the account of an IAM user, you need to obtain the required permissions and an AK/SK pair for the IAM user. For details, see How Do I Create an AK/SK Pair for an IAM User?

2. Install the SMS Agent on each ECS to be migrated. For details, see How Do I Install the Agent on Source Servers?
3. Run the SMS Agent and enter the AK/SK pair obtained in 1.
   

   After the Agent is started, it reports details about the ECSs to SMS, so SMS can check whether the ECSs can be migrated.

4. Log in to the SMS console using the account you are migrating to. Choose Servers from the navigation pane and view the ECSs in the server list.
5. Create and run migration tasks for migrating these ECSs. For details, see Configuring the Target Server, Starting a Full Replication, and Launching the Target Server.

   If the source and target ECSs are in the same VPC on Huawei Cloud, you can set Network Type to Private. Private connections will be established to the private IP addresses of the target ECSs, and data will be transmitted over these private connections. After the migration is complete, the target ECSs use the same login credentials as their paired source ECSs.

   

   • If the source and target ECSs are in the same account and the same region, but are in different VPCs, you need to create a peering connection between the VPCs so that you can migrate over a private network. For more information, see Creating a VPC Peering Connection with Another VPC in Your Account.

6. (Optional) Synchronize incremental data from the source ECSs to the target ECSs by using the Sync option on the SMS console.
