We have CUCM ver. 220.127.116.11-16 on platform 7825I3. We would like to do clustering and upgrading to 7.1 version. What we have to order ? Are these are correct?
CUCM 7.1 top level part number

Do we have to upgrade existing CUCM with version 6.1.3? And do we have to order CUCM ver. 7.1 or we can use from above order? We don't need devices license, do we (we use existing)?
