[cristian.munoz]

Hi Guys
I have 4 GWs model 2901, using IOS c2900-universalk9-mz.SPA.151-2.T5.bin and now I want upgrading to c2900-universalk9-mz.SPA.151-3.T4.bin. What is your version recommendation of IOS?

TIA
Cristian

I have 30+ of this particular model and am running 15.5(3)M6 without issue. Just my two cents.

Avoid using an IOS from the "T" train.  Use the "M" train for stability.
