Amazon EC2 Reserved Instances offer flexibility that includes the ability to modify instances, but modifications are subject to certain limitations. You can change the Availability Zone, the scope (regional or a specific Availability Zone), and the instance size within the same instance family, but you cannot switch between different instance families. This constraint is designed to maintain the reserved capacity for a particular family due to demand and capacity planning by AWS.
