[cisco-voip] CCM software upgrade differences

[Krzysztof]

Hi,

Can anyone tell me what is the difference between CM4.3-K9-MIG0 (SW
CallMgr 4.3 Same Server Class Migration) and CM4.3-U-K9-7835 (SW
CallMgr 3.3 To 4.3 Upgd, MCS-7835, 2500 Svr Usr Lic)? Both products
contain exactly the same set of CDs. The only difference I see is that
the first one is 500 USD and the second on is 5000 USD!!! Which one
should I then use to upgrade from 3.3 to 4.3?

Cheers,
Krzysztof
