6921 Firmware Upgrade Path?

[jameskuder]

I have some 6921 phones that are currently running firmware 9.0.2 and I am trying to determine what the upgrade path would be to get it on the latest version for that phone. I am assuming you cannot do a direct upgrade from one to the other. Any input is appreciated.

Hi James,

Here are the upgrade notes for the latest firmware 9.3.1;

Upgrade notes

Direct  upgrades, using signed load files, are supported to firmware releases  9.3(1) from 9.x. You can use the following firmware release file for  these direct upgrades.

• For Cisco Unified IP Phone 6901 and 6911: 
  • cmterm-6901_6911-sccp.9-3-1-2.cop.sgn
  • cmterm-6901_6911-sip.9-3-1-2.cop.sgn
• For Cisco Unified IP Phone 6921, 6941, and 6961 
  • cmterm-69xx-sccp.9-3-1-3.cop.sgn
  • cmterm-69xx-sip.9-3-1-5.cop.sgn
• For Cisco Unified IP Phone 6945 
  • cmterm-6945-sccp.9-3-1-3.cop.sgn
  • cmterm-6945-sip.9-3-1-5.cop.sgn

Note for Cisco Unified IP Phone 6901, 6911, and 6945:

• Direct upgrade to firmware release SCCP or SIP 9.3(1) is supported.

Notes for Cisco Unified IP Phone 6921, 6941, and 6961:

• Converting SIP to previous 9.1(1) SCCP does not work due to a known issue CSCtj89983. The workaround is to perform factory reset after upgrade completes.
• Converting previous 9.1(1) SCCP to SIP does not support Autoregistration due to a known issue CSCth26499.
• Direct  upgrade from firmware release 9.0(x) to 9.3(1) is supported. After you  upgrade from an earlier firmware release to 9.3(1) and for subsequent  firmware releases, you can upgrade or downgrade only to signed firmware  releases.
• If  you are using unsigned load and want to upgrade Cisco Unified  Communication Manager to release 8.6 and later then manually install  unsigned load to upgrade because phone load upgrade will fail due to  signed load in Cisco Unified Communication Manager by default.

What about if you have a phone on like 8.5.4.0?

Hi James,

Phones @ 8.5.4 would require a two-hop upgrade 8.5.4 to 9.0.2 & 9.0.2 to 9.3.1

Installation Upgrade Notes

Direct upgrades, using unsigned load files, are supported from firmware  release 8.5(4) to 9.0(2). You can use the following firmware release  file for these direct upgrades:

cmterm-6921_6941_6961-sccp.9-0-2-0-uns.cop.sgn
