Requirements for Modification
Modifying the Instance Size of Your Reservations
Submitting Modification Requests
Modification does not change the remaining term of your Standard Reserved Instances; their end dates remain the same. There is no fee, and you do not receive any new bills or invoices. Modification is separate from purchasing and does not affect how you use, purchase, or sell Standard Reserved Instances. You can modify your whole reservation, or just a subset, in one or more of the following ways:

Change Availability Zones within the same region
Change the scope of the reservation from Availability Zone to Region (and vice versa)
Change between EC2-VPC and EC2-Classic
Change the instance size within the same instance type
