Being lightweight and agile, Cloud Migration tool can live convert your physical desktops and servers or migrate virtual machines and cloud hosts to Alibaba Cloud ECS.

Cloud Migration tool overview

Cloud Migration tool helps you balance the workloads between your local and cloud hosts, or cloud hosts from different cloud platforms.

Specifically, our Cloud Migration tool is designed for P2V (Physical to virtual) or V2V (Virtual to virtual) use cases. P2V indicates building virtualization environments for your physical desktops or servers in ECS, while V2V indicates migrating VMs (virtual machines) or cloud hosts to ECS. Resources such as operating system, applications, and application data in physical machines, VMs, or cloud hosts will be live clone to ECS images by using the Cloud Migration tool. You can use the ECS images to start a specified numbers of ECS instances afterwards.

Some documents of Cloud Migration tool use on-premise server, source server or server to represent the source of migration to make it easy to read. Thus, the migration steps also applies to your physical machines, VMs, or cloud hosts.

The following figure describes the general process and outline when you use the Cloud Migration tool:



Applicable operating systems

Cloud Migration tool supports the following 32 or 64-bit physical machines, VMs, or cloud hosts:

Windows Linux
  • Windows Server 2003
  • Windows Server 2008
  • Windows Server 2012
  • Windows Server 2016
  • Amazon Linux 2014 or later
  • CentOS 5/6/7
  • Debian 7/8/9
  • Gentoo 13.0
  • OpenSUSE 13.1
  • Oracle Linux 5/6/7
  • Red Hat 5/6/7
  • SUSE 11.4/12.1/12.2
  • Ubuntu 10/12/14/16/17

Before migrating an operating system that is not listed previously, you must see topic Migrate to Alibaba Cloud by using Cloud Migration tool thoroughly and exercise with caution.

Billing details

Cloud Migration tool is free of charge. However, you may be charged for the following resource consumption:

  • During the migration, an ECS instance is created by default under your Alibaba Cloud account to act as an intermediate station. Billing method of the intermediate ECS instance is Pay-As-You-Go. In case you have put a limit on your credit card, you must delimit your credit card before the payment is attempted..

    Note If the P2V migration fails, the instance is retained on your ECS console for next migration attempt. If the migration fails, the intermediate instance is retained in ECS for the next migration attempt. You can log on to the ECS console and manually release the instance to avoid unnecessary charges.
