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. How do I do this?

To migrate an instance from one Dedicated Host to another, you can either allocate a new Dedicated Host to your account and move your Dedicated Instance to the new Dedicated Host, or edit the placement of the instance so the instance runs on another one of your existing Dedicated Hosts. You could also migrate your instance from a Dedicated Host to a Dedicated Instance and vice versa from the Amazon EC2 console by modifying the instance tenancy.

To allocate a new Dedicated Host to your account:

  1. Open the Dedicated Hosts pane of the EC2 console.
  2. Choose Allocate Dedicated Host.
  3. Choose an instance type and Availability Zone that matches the instance you want to migrate. For all other options, choose the setting that's best for your use-case.
  4. Choose Allocate Host.

To edit the placement of a Dedicated Instance, moving it from one Dedicated Host to another:

  1. Select the instance in the EC2 console.
  2. From the Actions menu, choose Instance State > Stop.
  3. From the Actions menu, choose Instance Settings > Modify Instance Placement.
  4. From the Target Host menu, select the new Dedicated Host you want the instance to run on.
  5. Choose Save.

To migrate an instance from a Dedicated Host to a Dedicated Instance:

  1. Open the Dedicated Hosts pane of the EC2 console.
  2. From the Actions menu, choose Instance State > Stop.
  3. From the Actions menu, choose Instance Settings > Modify Instance Placement.
  4. Change Tenancy to Run a dedicated hardware instance.
  5. Choose Save.
