Upgrade 20p PROM from 5.2 to 9.12?

My Vista 20p has been running 5.2 PROM since day 1 I just bought some used equip and it has a 9.12 PROM in it. Can I simply power down and replace the 5.2 with 9.12 PROM? Or ?

thanks for the help!

Since your configuration is stored in the PROM, there really is no advantage to just swapping the chip; since you would still have to reprogram all of your zones and settings.
