Hello,
I am planning an upgrade of our UC environment this weekend. I've been in contact with Cisco Licensing support all week to get the appropriate license for all the services. For CUCM I have ran the Pre Upgrade License Utility however they keep asking me for the ELM license request.
I've told them several times that ELM gets installed during the upgrade so I cannot provide the information beforehand. They've escalated my ticket to product management however i'm not sure i'll get a response before my maintenance window.
Can I proceed with the upgrade of CUCM/Unity/Presence and resolve the licensing afterwards? will it run in eval mode for a while?
Can someone also confirm this is the proper upgrade order?
CUCM Publisher Upgrade to 9.1
Unity Publisher Upgrade to 9.1
Presence Publisher Upgrade to 9.1
CUCM Subscriber Upgrade to 9.1
Unity Subscriber Upgrade to 9.1
Presence Subscriber Upgrade to 9.1
