As usual, mr. Rhoads is correct! (+5) Cisco does not have an upgrade/migration path for the FireSIGHT/FMC license. The rule applies for the Virtual instance as well. Thus, a new license would need to be purchased when moving from the 2 or 10 sensor version to the 25. This is why it is critical to size the FMC appliance correctly from the get go and include future growth.
With that said, you/the customer can work with the local Cisco team and try to work some sort of credit.
I hope this helps!
