First, check the conditions that are listed at [Requirements and restrictions for modification](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ri-modifying.html#ri-modification-limits). If your Reserved Instance meets the conditions, then you can request to modify the following attributes:


* Availability Zone
* Scope
* Instance size
* Network platform


If your modification request meets the guidelines and you’re ready to request a modification, then see [Submitting modification requests](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ri-modification-process.html).


If you purchased a Convertible Reserved Instance, then consider exchanging the Reserved Instance for another Convertible Reserved Instance. For more information, see [Exchange Convertible Reserved Instances](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ri-convertible-exchange.html).
