Hi @rasmusan1 , good question. I don’t see any upgrade license which would be a bonus.
if you look at this from a physical perspective I would treat as thus ie you’d need to build a new vMX and swap them over as so and procure a new license for the bigger vMX.
sorry, quite waffly but hope that makes sense
