Re: CUCM version in two different part

Hi Abdul,


Here is an example;


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_6.1.3.1000-16.sgn.iso, comprises two parts:




Step 1From,')">, download the two UCSInstall files.

Step 2Execute one of the following commands to reunite the two parts of the file.

NoteThe 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_6.1.3.1000-16.sgn.iso_part1of2 UCSInstall_UCOS_6.1.3.1000-16.sgn.iso_part2of2 > UCSInstall_UCOS_6.1.3.1000-16.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_6.1.3.1000-16.sgn.iso_part1of2+UCSInstall_UCOS_6.1.3.1000-16.sgn.iso_part2of2 UCSInstall_UCOS_6.1.3.1000-16.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!
