[cisco-voip] IP Phone Firmware conundrum

[Michael Balasko]

3.3.4? HA!!! That's modern! I rolled from 3.0.1 to 6.1.2 on some 7960G's and they worked fine. It felt like the CCM's rebooted the phones a few times and after the upgrade all was happy.

We are in the process of upgrading a customer that has an existing ccm 3.3.4 deployment. Due to the nature of the old hardware and other issues the call has been made to bypass the DMA phase, Cisco created the licenses for the Devices as if in a new deployment, this part is ok. The issue comes in the fact that the phones currently in service are running old firmware from the 3.3.4 code of ccm. I am 98% sure that there is a need to move the phones to an intermediate load as they will probably fail to jump from such an old fw to the recent versions of fw code within 6.1 If anyone has done and upgrade such as this and can shed some info it will be greatly appreciated.
