Switch from AWS EC2 reserved instance to Saving Plan

Question

Dear Team - We have purchased AWS Reserved instances for our EC2 instances. Total approx coverage of RI for EC2 is around 78% last month. Now our team has decided to change the strategy and use saving plan instead.

Is there any way i can request aws to change reserved instance to saving plan of same amount ?                    
if above not possible, what is the best practices to switch to saving plan with maintain the same % of coverage ?

Hi JD,

Ordinarily,  you cannot cancel reserved instances, as they are considered to be a commitment to a certain platform on AWS (which is why you receive a discount in exchange for the purchase from AWS). After you have purchased a Reserved Instance, you may be able to [modify](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ri-modifying.html), [exchange](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ri-convertible-exchange.html), or [sell](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ri-market-general.html) your Reserved Instance if your needs change.

Effectively this means, that unless the above 3 avenues are viable for you, that you need to wait for your reserved instance to expire, before you can purchase equivalent savings plans to cover them.
