# Change the instance tenancy of a VPC
<a name="change-tenancy-vpc"></a>

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 EC2 instance](dedicated-change-tenancy.md).

**Limitations**
+ You can't change the instance tenancy of a VPC from `default` to `dedicated` after it is created.
+ You can't modify the instance tenancy of a VPC using the AWS Management Console.
