What is cloud migration tool and P2V

The cloud migration tool is specially developed to balance the load of online and offline servers of ECS users or the load between various different cloud platforms. With its lightweight and convenient features, the cloud migration tool supports online migration of physical servers, virtual machines and other cloud platform cloud hosts to the ECS classic network platform or dedicated network platform to achieve the purpose of unified deployment of resources.

Cloud migration tools belong to the category of P2V or V2V tools. P2V (Physical to virtual) represents migration from the physical IDC environment to ECS, and V2V (Virtual to virtual) represents migration from the virtual machine environment or cloud platform host to ECS. The cloud migration tool can migrate the operating system, applications and application data in the computer disk to ECS or a virtual disk partition to generate an ECS image. You can use this image to quickly create ECS instances to achieve P2V and V2V.

Billing details

The cloud migration tool is a free tool and does not charge additional fees. However, a small amount of resource billing will be involved during the cloud migration process:

During the cloud migration process, a snapshot will be created to generate a custom image, and a small fee will be charged for this snapshot based on the actual occupied capacity. Please refer to Snapshot Service Fee Details for details.

When migrating to the cloud, the system creates an ECS instance with the default name INSTANCE_FOR_GOTOALIYUN under your Alibaba Cloud account as a transfer station by default. The payment type of this transit instance is pay-as-you-go. You need to ensure that the account balance is greater than or equal to 100 yuan. For resource consumption and billing instructions generated by pay-as-you-go instances, please refer to Pay-As-You-Go instances.

Note: After the cloud migration fails, the instance remains in the ECS console to facilitate re-migration to the cloud. If you no longer need the instance, please release the instance yourself to avoid unnecessary deductions.
