We are currently on CM 4.1(3) and looking to go to 6.x. From the Product Upgrade tool, I see the following are our entitled upgrade options:
CM4.3-K9-SUP= SW CallManager Upgrade 4.x To 4.3
CM5.1-K9-SUP= SW Upgrade CM 4.1 to 5.1 for SMARTnet
CM6.0-K9-SUP= SW Upgrade CM 5.1 to 6.0 for Cisco SMARTnet
CM6.1-K9-SUP= SW Upgrade CM 5.0/5.1 to 6.1 for Cisco SMARTnet
From the listed items, there is no direct patch to 6.1(1), but it is my understanding that this is possible. Is it just an error with the PUT? Should I just be able to order CM6.1-K9-SUP= for my three servers?
Also, if I have two 7835s and one 7825, would I need platform-specific disks?
In this case I would order the 5.1 and 6.1 media path both, so that there is a record trail of your upgrades within PUT.
But you are correct, you use the 6.1 upgrade kit to go directly from 4.1.
And there are no longer multiple platforms discs, all platforms are covered by a single DVD. As of 5.x Cisco moved away from using platform specifics images and instead use normal OS/application package installers combined with a hardware check.
