Phone Firmware Upgrade Question

[baduniswapan]

Hi  I am upgrading the firmwares of a lot of phones.

 
Current Firmware

SCCP41.8-5-3S    216

SCCP42.8-5-3S    3675

SCCP42.9-2-1S    13

P00308010200    25

Required Firmware

SCCP41.9-3-1SR1-1S   

SCCP42.9-3-1SR1-1S   

Can I go straight from the existing versions or do I need to do step  upgrades?

Thanks.

Hi,

You can upgrade directly.The release notes says :

For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to Version 9.3(1) or

later, you must first upgrade your phone firmware to an intermediate version (8.3(3) to 8.5(2)) and then

upgrade to 9.3(1).

In your case, you are already running 9.2(1S) and 8.5(3s)

regds,

You can go direct.

The following upgrade issues apply:

•If you are currently running firmware earlier than 6.0(2) on a Cisco Unified IP Phone and want to upgrade to 8.x(x), you must first install an intervening 7.0(x) load to prevent upgrade failure. Cisco recommends using the most recent 7.0(3) load as the intervening load to avoid lengthy upgrade times.

•If you are currently running firmware 6.0(2) to 7.0(2) on a Cisco Unified IP Phone and want to upgrade to 8.x(x), you can do so directly. However, expect the upgrade to take twice as long as usual.

•Device packs are required to enable IP Phones in the Cisco Unified Communications Manager database. For Cisco Unified CallManager 4.2 and earlier, these device packs are required. For Cisco Unified CallManager 4.3 and Cisco Unified Communications Manager 6.0 and later, you must run the device pack and reboot the Cisco Unified Communications Manager server.
