Upgrade to CUCM v14

[Engnr]

Hi there,

Question for those who upgraded CUCM to v14, I wonder what you guys mapped 7500 users OVA of CUCM v12.x to CUCM v14 equivalent, while doing the upgrade to CUCM v14?https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/virtualization-cisco-unified-communications-manager.html

Medium example VM or Large one? 

Thx

Medium is for 5000 devices with up to 5000 users and large is for 20K-30K devices with 10K-20K users. Based on the number of devices and users  in your infrastructure select medium or large.
