New feature: Server Migration Service.

Server Migration Service (SMS)  is a feature that allows the user to migrate physical or virtual servers (e.g. VMware) including the OS and all related data to the Flexible Engine platform. SMS allows you to seamlessly and efficiently migrate servers with just a few clicks.

This feature works by deploying an agent installed on the source server that will replicate server data to prepare for a migration task. You can access SMS through the Flexible Engine technical console and selecting the Paris (EU-West-0) region.

More information and technical documentation for SMS is available here.

Use cases

  • Online migration: it is also called online cloning. The server to be migrated is in the running state. After the server is migrated, users need to switch services to the destination ECS and verify the application availability.
  • File-level migration: it refers to the process of copying the files and directories in the source disk to the destination ECS during migration.
  • Block-level migration: it refers to the process of reading data from the source disk sector and migrating the data to the destination ECS in sequence.
  • High security migration: SMS uses AK and SK to authenticate migration agent identities. SMS uses SSL protocol to encrypt the transmission channel to ensure the security of your data.    The certificates and secret keys used for SSL encryption are dynamically generated.
