-- We are retiring EC2-Classic. We recommend that you migrate from
-- EC2-Classic to a VPC. For more information, see
-- <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/vpc-migrate.html Migrate from EC2-Classic to a VPC>
-- in the /Amazon Elastic Compute Cloud User Guide/.
--
-- Links an EC2-Classic instance to a ClassicLink-enabled VPC through one
-- or more of the VPC\'s security groups. You cannot link an EC2-Classic
-- instance to more than one VPC at a time. You can only link an instance
-- that\'s in the @running@ state. An instance is automatically unlinked
-- from a VPC when it\'s stopped - you can link it to the VPC again when
-- you restart it.
--
-- After you\'ve linked an instance, you cannot change the VPC security
-- groups that are associated with it. To change the security groups, you
-- must first unlink the instance, and then link it again.
--
-- Linking your instance to a VPC is sometimes referred to as /attaching/
-- your instance.
