Hello Bhavesh,
in terms of VAM2+ , yes this is the time where customer to go for an upgrade but, did you get a chance to see what is the total IPSEC traffic on the interface. VAM2_ card can support upto 280 mbps. If teh existing traffic expected is much lower to the capacity then we might not required to go for an upgrade. And in 7200 persepctive, i belive the throughput is around 450 mbps.
So in nutshell, if we are not expecting more than 1000 tunnel in near future and the traffic is less that 280 mbps.. we are in a good position i would say

Harish.
