You might want to get with a local Cisco Partner who can get more details about your environment and discuss best practices. It might cost you some money, but save you headaches. Hands on upgrade experience counts for a lot.  You can mess up a lot of things but you take down  the telephones and your manager and everyone else might not  be too happy. There are a lot of considerations not just the phone load.

Other option would be to do a BARS backup/restore in VMWare and lab test your project plan.

The strange things is that Cisco tell me to preupgrade to the latest firmware supported on target version, so CUCM 8.5 version,
they give me this pointer:

If is it true, before start CUCM upgrade procedure,  I'll need to setup a separate TFTP server, and I'll need to upload to it all latest phone firmare files..

So for me is too much time expensive, and I think it will unnecessary.

What do you thing about?

Thank you!

Alessandro

Are they telling you to upgrade to the latest firmware supported on CCM 4.2.3 or to upgrade to a CUCM 8.5 firmware?


Thanks!

Yes Yes, I know!!!

But my doubt is that, Cisco say that is necessary to preupgrade phone firmware, before they connect for the first time, to the new CUCM cluster?

Is this true?

Alessandro -

When you upgrade from CCM 4.2.3 to CUCM 8.5, you'll for sure need to update the firmware in your phones.  The updated TFTP server should address this for you once your phones register for the first time with the newer CUCM cluster.

What model of phones do you currently have?

I don't understand your concern about cost concerning phone firmware.

 Hi Guys, I need to upgrade CCM 4.2.3 to CUCM 8.5, Cisco telle me that I must, before upgrade CUCM, upgrade Firware Phone with last firmware files.

For me is much expensive to do so!!!!

The question is, Is really necessary to upgrade Firmware phones before upgrading CUCM 4.2.3 to CUCM 8.5?

thank you for the answers
