I am hoping to receive feed back from our Cisco SBCS support team in regards to this question if possible?
I have attempted to upgrade the office demo UC520 with versions 7.1.3 and 8.0 but in both cases the full upgrade starts then aborts stating this is not a valid package.
I have tried to unpack,minimize and repack the bundle as per some partners suggestions in these discussions. I have verifed the version of CCA and CUE are current. I have removed all extraneous localization, phone and wav files to be sure I have maximum space but in the end had to revert to the CLI to upgrade discreet portions of the package.
Is it possible for Cisco to identify a minimum starting point you need to have to be successful with a pkg upgrade via CCA (or CLI for that matter)? It would ideal if the list identifed minimum hardware (IE: RAM & DRAM requirements), CCA, CUE and IOS versions and base flash files to start with.
I apologize if this has been identifed prior but I have searched this discussion and global cisco.com with no success.
