It's likely that VM will force all the modems to reconnect soon-ish after upgrading each card anyway. In addition if you aren't on an upstream channel with a symbol rate of 5120ksym/s - you should be able to see this from your cable modem - you aren't getting upgraded yet, it's a prerequisite.
How do I see the symbol rate? I am guessing my modem is hiding it. Is scientific atlanta.
