I have callmanager 4.1.3SR4d and noticed that there is a download for the OS with the following name: win-OS-Upgrade-K9.2003-1-1-sr3.exe
It appease it's based on windows 2003 OS. Went on CCO to download but it says it requres
'Fresh install of OS 2003.1.1.
It doesn't seem like it can be, but, just in case anyone has done this already, is there a way to upgrade this from the win-OS-Update-K9.2000-x-x-xxx.exe trains or it's only via a fresh install?
Thanks in advance!
