Change the instance tenancy of a VPC

You can change the instance tenancy of a virtual private cloud (VPC) from dedicated to default after you create it. Modifying the instance tenancy of a VPC does not affect the tenancy of any existing instances in the VPC. The next time that you launch an instance in the VPC, it has a tenancy of default, unless you specify otherwise during instance launch.

Alternatively, you can change the tenancy of specific instances. For more information, see Change the tenancy of an Amazon EC2 instance.
