Which FOS should I install on 24k director and 3900 switch?

I need some help regarding upgradation of FOS on my 24k director and 2 of 3900 edge switches. Currenlty they have v 5.3.1. I read most of the Release notes for the new firmware but they didnt happend to mentioned 3900 and 24k directors.

If some one can help me on this that would be really appreciated

ok thank you, but what about 3900 Switchs which I have sitting on my datacenter on v 5.3.1. I cannot update their FOS above v 5.3.2

And another question arises is that, can I have my edge switched on Higher FOS that is v 6.x and my core director 24k sitting on FOS v 5.3.2

Will that work

We're upgrading to 5.3.2c on our older 24Ks and 3900s.  Will apply any additional patches if / when they come out.

hey thanks for getting back, Now I got it. But anyways, will this work if my 24k Director is on FOS v 5.3.2c and all the other edge switches connected to it are on  FOS v6.3.x

which other SWs you have , those you can take it to 6.3.x. if you keep 24K to  5.3.2C and you can upgrade other SWs, to 6.3.x no issue, but better you change ur core SW .

better you can make the 6.3.x one to core and make the same principal too by fabricprincipal cmd

3900's last FO Sis 5.3.2c
