How Can I Migrate Xen ECSs?

All versions of the Xen software used by Huawei Cloud have reached end of life. You need to change Xen ECSs to KVM ECSs before the migration.

Preparations

Checking Whether Your ECSs Use Xen

You can determine whether an ECS uses Xen based on its flavor in the basic information of the ECS. Xen ECSs include C1, C2, S1, M1, E1, E2, ET2, D1, H1, G1 and G2 ECSs.
