[cisco-voip] 4.1 to 5.1 upgrade released. Why not from 4.2?!!

[Anthony Kouloglou]

Hi all,
i am really pissed of with cisco's customer support.
They really don't tell what exactly is going on.
I just want to upgrade 2 of my 7825i2 servers running 4.2 ccm to 5.1.
It has been 2 weeks that they are telling me that there will be soon an 
upgrade and 5 days ago
they told me that it is ready and to go to PUT to download it!!
I went to PUT web page and i found out that it was an upgrade from 
4.1->5.1!!
I told them that i have 4.2 and i am still waiting for their response!!!

Has anyone find a way to upgrade from 4.2 to 5.1?

Cheers
Anthony
