Mature Cyclone 2 Migration Questions

We have a legacy design that originally used a Cyclone 2 FPGA:

EP2C15AF484C6N

that we can't get quoted from authorized distributors likely due to the geriatric age of these devices. I found that:

EP2C20F484C6N

will be available at an authorized distributor next month.

I know this part has the same footprint (FineLine BGA, 484 pin count) and same speed grade. It has more LEs (logic elements): 14,428 on the EP2C15A vs. 18,752 on the EP2C20. We DO NOT need the Fast-On capability.

If the FPGA is changed from the 15A to the 20 device, can the old .pof file be used without doing any re-compilation, especially since the Quartus version in question is no longer supported?

Can we simply drop in the EP2C20 device in for the EP2C15A and a high level confidence it will work, without having to change anything?

-Thanks-
