Upgrade phone firmware

Hi,

 

I am looking to migrate cucm 8.5.1 to 9.1.2 version. The question is whether I need to upgrade firmware for all Cisco IP Phones.

 

Please help to your advice!

 

Best regards,

Tan

Re: Upgrade phone firmware

Look at the CUCM SW compatibility matrix for the FW that comes with 9.X, then compare to what your phones currently have, and you'll have your answer.

Dear Tan, corroborating Jaime

Dear Tan,

 corroborating Jaime, you are not likely going to need firmware upgrade.
