[c-nsp] Upgrading VPN 3000's.....any advice?

[ChrisSerafin]

Hello all,

I planning on upgrading 2 different VPN3000's to the most current stable 
code. One of them is running 4.7 and the other is running 4.1.7H.  I 
thinking of running 4.7.2L.  Does anyone have any recommendations or 
caveats I might run into? Also would one of these upgrades cause the 
device to go into ROMMON mode like a router with IOS?

Thanks all,
