Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

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 Amazon CLI, an Amazon SDK, or the Amazon EC2 API only.
