Hello All,
I am on cisco and looking at the Firmware release notes to upgrade my cisco 7940 phones to 8.1 SR2. I know that I first have to upgrade to 8.1.1 then 8.1.SR2. My phones are currently at P00307020200 and the CME 7.0 only goes up to P00308000500. I am migrating these phones from a CME to a cluster which the phones will then need to upgarde to P0030801SR02. What I would like to know is how do I navigate on Cisco to back track which upgrades I will need to do to get to P0030801SR02??? I was able to look at the Release notes for 8.1 SR2 and it told me to first get 8.1.1, I then looked at 8.1.1 thinking it would tell me to first upgrade to something, but it didnt tell me what I needed to get to 8.1.1. I am really green when it comes to upgrading firmware, so any help would be greatly appreciated.
