I want to upgrade my cucm 6.1(2) to 6.1(3) i have downloaded two very large files with .iso_part1of2 extensions. Do i need to remove the extension from the file and leave just .iso ?
i looked for support documentation but cant find anything useful other than telling me to create a ISO DVD for the uprade which failed when i tried (im using Nero)
any help appreciated
At the end of the day, I believe the file should look like this;
Upgrading From Cisco Unified Communications Manager Release 6.1(1x) or higher to Release 6.1(3) by Using the UCSInstall File
Because of its size, the UCSInstall iso file, UCOS_188.8.131.520-16.sgn.iso, comprises two parts:
Step 1From www.cisco.com, download the two UCSInstall files.
Step 2Execute one of the following commands to reunite the two parts of the file.
NoteThe 184.108.40.2060-16 build represents a non-bootable ISO that is only useful for upgrades. You cannot use it for new installations.
a.If you have a Unix/Linux system, cut and paste the following command from this document into the CLI to combine the two parts:
cat UCSInstall_UCOS_220.127.116.110-16.sgn.iso_part1of2 UCSInstall_UCOS_18.104.22.1680-16.sgn.iso_part2of2 > UCSInstall_UCOS_22.214.171.1240-16.sgn.iso
b.If you have a Windows system, cut and paste the following command from this document into the command prompt (cmd.exe) to combine the two parts:
COPY /B UCSInstall_UCOS_126.96.36.1990-16.sgn.iso_part1of2+UCSInstall_UCOS_188.8.131.520-16.sgn.iso_part2of2 UCSInstall_UCOS_184.108.40.2060-16.sgn.iso
Step 3Use an md5sum utility to verify that the MD5 sum of the final file is correct.
From these Release Notes;
Hope this helps!
