Hi Cisco Team,
I wish to give my heart felt thanks to the CCA dev team for the latest version (3.2.1), out of the many CCA's I have used over the years this has to be the best revision thus far.
In short I had to do a complete overhaul of a UC-520 last night from its original configuration which was done using "CCC" which was part of an Early Fields Trial test, the system was in a very aged state and in desperate need of the overhaul. CCA managed to upgrade both the CME and CUE with no troubles, which for me has been the first time this has been achievable, in fact when you press the "F2" command to review what's taking place, I noticed that its error handling is significantly improved over previous versions.
I cannot imagine the time and effort that was put into bringing this version to market, but it certainly has improved the ability to rebuild a system from scratch without major drama, what was more impressive is that it allowed an upgrade of the CUE from version 3.2 to 18.104.22.168 without incremental upgrade procedures which I have had to do multiple times in the past... This alone is worthy of praise
The only trouble I had was with the 7941/7961 phones, many of them would not upgrade due to their firmware version, all the 7965/7970 phones upgraded happily even though their firmwars were pretty much original manufacturers... I do however have two phones that are in a semi bricked state now due to this firmware issue, and am not sure how I am going to recover them from this state, but I do know they require a firmware upgrade to recover them.
So any thoughts on the above would be greatly appreciated
David.. I have used TFTPD running on a laptop on a isolated network to flash 7941's to the 8.5.2r1 rev so they can go to 8.5.4 with the automatic upgrade on the uc560.
Here is a link that explains it better as you are not converting but using this as a guide for an offline upgrade.
Cisco really needs to come out with an app that will do this easily.
