I have the following version of IOS,CME,CUE on my UC-520
IOS 12.4(11)XW6, RELEASE SOFTWARE (fc2)
CME 4.2(0)
CUE 3.0.3
I would like to upgrade to the newest version of Software pack 8.0.2 CCA 2.2 is installed
can I do this direct upgrade from such lower version to the latest one using CCA?
or do I need to the upgrade to the next immediate version and then to the latest version?
also Please suggest me with the proper upgrading procedure.
Thanks

Hi techmandy,
Will the upgrade go smoothly, i hope so.
I have had one or two problems with upgrades over the years, but I have upgraded as a release comes out. I did have a problem with a access list and zone based firewall, but that was easy to find. CCA 2.2.4 is a lot more sophisticated compared to earlier releases.
I have seen posting such as "Cue does not work after 3.2 => 7.0.3 upgrade" where the upgrade was not successful.
Was your configuration produced via 'out of band' CLI configuration, or was the configuration produced by Cisco Configuration Assistant ? Don't know, to many variables to guess if it will work for you.
To play it safer;
You will notice that when you run CCA 2.2.4, can you still manage your current system. If you can use 2.2.4 to add or modify system options, I would think that you should be safe to just give the upgrade a try.
That's my thoughts, others looking at this post may disagree. You always have the option to spend the time, if you feel better about it and upgrade the system release by release..
have fun and good luck.
regards Dave

I too have the same situation related to this
Can you please help me with the follwing questions ?
1. If I take backup of the complete CF card will I be able to restore it back if anything goes wrong ?
2. DO I need to unzip the software pack for upgrade? I have tried pointing the .ZIP file through CCA is said the file is not compatible for this upgrade.
I head CCA will scan the ZIP file and present the options of selections.

HI techmandey & sunilgavaskar,
Let me firstly say, any upgrades you do must have the following done in order to increase the success rate and decrease the failure rate.
The upgrading stage:
Following the above procedure i have successfully upgraded many UC-520's from the very first IOS when they were first introduced to the very latest IOS, but i would be telling porkies if i said they all went smoothly, after all we are talking about Cisco here
nothing ever goes smoothly LOL. You will be fine as long as you have sufficiently prepared yourself, and you are also willing to put some configuration time into the system, if you expect it to all just fit in the spaces correctly, then you are going to be in for a rude shock, for a full CME and CUE upgrade I woudl allocate 3 hours maybe 4 just incase you had to tidy up the config a little more then expected.Programs to use:
That is all i can think of for now, i hope it all goes well for you both and that you only receive very small upgrade pains, even better if none at all.
Cheers,
David.

Hi,
Upgrade process from earlier 7.0 version to 8.0.2 was successful and did not find any issue through the process
for the reference these are the steps followed
Did backup of the configuration using CCA 2.2(4)
disabled the local firewall on the system
checked for any third party FTP/TFTP services (I did not have any)
under maintenance tab on CCA did the upgrade settings pointed the software pack(8.0.2) which was already downloaded(zip file)
selected the phone firmware to upgrade (also selected apply factory default since I wanted to start fresh config)
continued with the upgrade process. it gave the estimated time of 1 hour but took only 30 minutes to complete all IOS, CME,CUE versions(It also shows the status of the upgrade step by step)
Reloaded the box
that's all !!!!!!!!!!!
(in order to avoid chances of failures better to follow all the steps though few are not necessary for your environment)
Thanks Dave and David for all your detailed suggestions.
