Polycom 450 Downgrade from 3.3.2 to 3.2.6


i have a polycom 450 that has been upgraded to v3.3.2 and i need to downgrade back to the 3.2.6. how do i do so? it appears i need to just download the older firmware, connect to the IP address assigned to the phone and use FTP to download the firmware. is that a correct assumption?
