Server migration services are provided free of charge. However, during the migration process, costs may be incurred for aspects such as intermediate instances and networking. This document explains the potential cost items and billing methods associated with server migration.
Relay Instances
If the migration destination is a Cloud Virtual Machine (CVM) image, a relay instance named
do_not_delete_csm_instance will be created under your account after the migration starts. The instance incurs instance fees and cloud disk fees.Billing mode: pay-as-you-go
Do not reinstall, shut down, or terminate the relay instance or reset its password. It will be automatically terminated by the system after the migration ends.
Network Traffic
Network traffic is generated during online migration, which is billed as follows:
For migration over the public network, if your source server has a bandwidth plan, no additional fees will incur on the source server. The inbound traffic on the destination CVM does not incur fees.
For migration over the public network, if your source server is billed by traffic, traffic fees will incur on the source server. The inbound traffic on the destination CVM does not incur fees.
Establish a connection channel through VPC peering, VPN connection, Cloud Connect Network (CCN), or Direct Connect. The costs are based on the specific network fees.
