Q 1. Can I change from on-demand to RIs on the fly?

A) Yes – you can switch from on-demand to Reservations on the fly.  

Azure Portal >> Navigate to All Services >> Reservations >> Click Add >> Define a scope and create.

You don’t assign that reservation to a specific VM, rather, the discount is applied at the subscription level  automatically

Q2) Can I upgrade the size of my reserved instance?

A2) Yes, you can increase / decrease the size of your reservation (entails a restart).
