does anybody know what part I need to order if i want to upgrade from 4.1(3) to 4.3(1)
Here is the related info :)
For upgrades or new installations of Cisco Unified CallManager 4.3, Cisco Unified CallManager CDs must be ordered.
Customers with a Cisco Software Application Support plus Upgrades (SASU) contract or a Unified Software Subscription, who are running Cisco Unified CallManager Versions 3.3(5), 4.0(2a), 4.1(3) or 4.2(x) and want to upgrade to Cisco Unified CallManager Version 4.3 can order a free upgrade by using the Product Upgrade Tool (PUT) located at:
Customers without SASU who require a CD upgrade can order one of the Cisco Unified CallManager part numbers in Table 1.
CM4.3-K9-UPG= SW CallManager Upgrade To 4.3 For SASU/UCSS
CM-4.3-K9-SUP= SW CallManager Upgrade To 4.3 For SMARTnet
Hope this helps!
