The military has been ready for years now. PA is significantly outclassed and PAF even more so.
In 2019 the IA had enough ammo for a one-front war, whereas now they have enough for both fronts. IAF was still in the 3rd/4th gen era, and now in the 5th gen. Both now have the most modern communications and networking technologies. EW and cyberwarfare capabilities have gone through the roof. The biggest change was seen in the IAF with the inductions of Rafale, S-400, and MRSAM. Plus pretty much everything old we have has been upgraded. We have even deployed soft and hard-kill CUAS. And, unlike Pakistan, we are flush with money.
I wish we had brainstorming in past amongst our think tank and would have planned something for this sort of Scenario. Sometime doing something is easier to conceiving proper response which should be appropriate.
