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?

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 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 EC2 console by modifying the tenancy of the instance.

To allocate a new Dedicated Host to your account

  1. Open the Amazon EC2 console, and choose Dedicated hosts from the navigation pane.
  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 fits your use case.
  4. Choose Allocate Host.

To move an instance from one Dedicated Host to another

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