Hi,

Yes, you can upgrade Reserved EC2 Instances to larger types: the formal procedure to do so is documented here

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ri-modifying.html

There is also a procedure to exchange Reserved Instances documents here: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ri-convertible-exchange.html

Best,
