Overview

This best practice describes the detailed procedure and precautions for migrating servers from Alibaba Cloud to Huawei Cloud.

The key steps include:

Making Preparations: Ensure that the migration accounts are available and the accounts have required permissions.
Installing the MgC Agent: Download and install the MgC Agent, a tool provided by MgC.
Discovering Resources: Collect information about the Alibaba Cloud ECSs to be migrated.
Assessing Migration Readiness: Check the configuration of the Alibaba Cloud ECSs to be migrated, test their network connectivity, and gather them into groups.
Assessing Target Servers: Get recommendations for Huawei Cloud resources and configure target servers for source servers.
Creating a Workflow: Create a migration workflow to migrate your source servers.

Before creating a server migration workflow, read and understand the following precautions.

Item	Precaution
Source download bandwidth	Used to download SMS-Agent to source servers. If each source server uses a dedicated bandwidth, the bandwidth must be at least 30 Mbit/s. If source servers share a bandwidth, the average bandwidth must be at least 50 Mbit/s.
Migration bandwidth	Used to migrate data. It affects the migration speed and duration. For details about how to estimate the migration duration, see How Long Does a Migration Take?
CPU and memory	At least 520 MB of available memory At least 0.3 CPUs available in Linux and at least 1 CPU available in Windows
OS compatibility	For details about what OSs are supported, see Supported OSs.
Server migration statements	For details about the important statements you need to understand before the migration, see What Are the Important Statements of SMS?
Notes and constraints	For details about the notes and constraints for server migration, see Notes and Constraints.
Billing	For details about the fees that may be incurred during the migration, see Billing.
Permissions configuration	For details about the permissions the target account must have, see Permissions Management.
Migration network and ports	For details about the requirements for the migration network and ports, see How Do I Set Up a Secure Migration Network for Using SMS?
