9.x User License can be used in CUCM 10.5?

[HUI YI CHEN]

My customer order  9.x User License, but they want the lastest CUCM 10.5 to be installed.

Can I install CUCM 10.5 directly with 9.x user license?

or I have to install CUCM 9.x, then upgrde to 10.5?

Thanks,

Hello, huiyi_chen. You can install the 9.X User license and then upgrade directly to 10.5. Check this link for direct upgrade path to CUCM 10.5:
