Q: Can I move a Reserved Instance from one Region or Availability Zone to another?

Each Reserved Instance is associated with a specific Region, which is fixed for the lifetime of the reservation and cannot be changed. Each reservation can, however, be used in any of the available AZs within the associated Region.

When you exchange one Convertible Reserved Instance for another, EC2 ensures that the total value of the Convertible Reserved Instances is maintained through a conversion. So, if you are converting your Reserved Instance with a total value of $1000 for another Reserved Instance, you will receive a quantity of Convertible Reserved Instances with a value that’s equal to or greater than $1000. You cannot convert your Convertible Reserved Instance for Convertible Reserved Instance(s) of a lesser total value.
