ability to convert from Pay-As-You-Go to RI
All users know upfront that RI is good savings over Pay-As-You-Go.
But as a user when we purchase an instance most of the time we are not sure whether the instance we purchase meets our needs, so the user purchase the Pay-As-You-Go to evaluate.
Eventually if they are satisified they would like to make a long term committment, thats when they will think about upgrading to RI.
But in Azure there is no availability of upgrade path.
It will be great if Azure could provide this option.
