Our customer wants to upgrade the current callmanager 5.1 to the callmanager 6.1 for some new features.
So what would be the upgrade process? what steps and tools I need to complete the upgrade successfully? Should I use the upgrade assistant and DMA to migrate the data from CM5.1 to CM6.1?
And what about the license? How can i obtain the new cm6.1 license ? I haven't found any guide about it.
Can anybody help me? Thanks very much.
