Cloud Migration tool and P2V

Last Updated: Jun 25, 2018

Cloud Migration tool balances the workloads between your local and cloud hosts, or cloud hosts from different cloud platforms. Being lightweight and agile, Cloud Migration tool can convert your physical desktops and servers or migrate virtual machines and cloud hosts to ECS.

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. Afterwards, you can use the ECS images to start a specified numbers of ECS instances.

Applicable operating systems

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

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

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

Billing details

Cloud Migration tool is free of charge. However, 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 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.
