This document explains Licensing CUCM 10.x with Cisco Prime License Manager (PLM)
Cisco Prime License Manager
Cisco Prime License Manager (Prime LM, formerly Cisco Enterprise License Manager) aligns with the Cisco Prime management suite of products. Cisco Prime LM offers new features and capabilities and adds support for Cisco Emergency Responder. Cisco Prime LM also supports multiple clusters and multiple versions of products, such as Cisco Unified CM versions 9. x and 10. x .
If you choose to remain on Cisco Enterprise License Manager (ELM) 9. x and have 10. x clusters, ELM can support both Unified CM version 9. x and 10. x with an update from a Cisco Option Package (COP) file; however, Cisco highly recommends upgrading to Cisco Prime LM to leverage new features and functions.
Cisco Prime LM currently supports the following Cisco Collaboration applications:
Cisco Unified CM
Cisco Unified CM Session Management Edition (SME)
Cisco IM and Presence Service
Cisco Unity Connection
Cisco Business Edition 6000
Cisco Emergency Responder
Cisco WebEx Meetings Server
