Change the tenancy of a Amazon VPC
You can change the instance tenancy of a VPC from dedicated to default
after you create it. Modifying the instance tenancy of the VPC does not affect the tenancy of any
existing instances in the VPC. The next time you launch an instance in the VPC, it has a tenancy of
default, unless you specify otherwise during launch.
Note
You cannot change the instance tenancy of a VPC from default to
dedicated after it is created.
You can modify the instance tenancy of a VPC using the AWS CLI, an AWS SDK, or the Amazon EC2 API only.
