one of our customer wants to upgdate their CUCM from 7.1.3 to 9.1.
Hardware Used : MCS 7825I4 two clustered Publisher / Subscriber servers.
can we install the new version on these servers ??
how the license will be migrated?
7825 I4 shows supported with memory/HDD upgrades listed at the bottom of the link
License migration is discussed in detail here. Need partner access
Do keep in mind that 10.0 will be a virtual only release so 9.1 will be the last release to support MCS. If you don't move now you will have to make that jump eventually in 10.0 to virtual
Just wanted to add that you will want to upgrade the memory and HDD before doing the upgrade to 9.1.
