How do I migrate a Dedicated Host or Dedicated Instance to another Dedicated Host?

Last updated: 2019-05-07

I want to migrate an instance running on dedicated hardware (a Dedicated Host or Dedicated Instance), or I received a maintenance notification and have a scheduled event for an instance running on dedicated hardware. What should I do?

Short Description

To migrate an instance away from a Dedicated Host, do one of the following:

  • Allocate a new Dedicated Host to your account, and then move your Dedicated Instance to the new Dedicated Host.
  • Edit the placement of the instance so that the instance runs on another one of your existing Dedicated Hosts.
  • Migrate your instance from a Dedicated Host to a Dedicated Instance, and vice versa, from the Amazon Elastic Compute Cloud (Amazon EC2) console by modifying the tenancy of the instance.
