I don't. Such upgades are already planified/prepared a long time before a contract/order is signed : I heard about it when visiting the french AWACS airbase in 2006 & 2008.
Sorry, I can't remember accurately, but public sources are available (press, websites...). They were (at last) two upgrades under way, regarding :
- mission system (radar...) (IIRC this is the one recently announced)
- vector systems (new avionics)
Agreed for the point of Red Air.

But... The initial statement was : 4-0 then 3-1 with "limited weapons"
for the Rafale.
Unless I'm seriously mistaking, Blue Air "plays" with its own, "real" strengh (capabilities ; except for those you don't wanna show to you allies/comrades/customers/...).
On the other hand, Red Air "plays" the role of a defined opponent, for example : "today, you're red air, and you simulate Flankers armed with Alamo A".
Then, if one side "limits" its weapons capabilities, doesn't that mean that this side plays Red Air ? And faces a "full capability" Blue Air ?
Wondering...
