ACI Upgrade 5.x Hardware caveats

Hi experts, we have a fabric 4.2

and i want to upgrade it to 5.x

but we have some spines 9336PQ i believe this one are 1 gen

so in this link, shows that the cisco ACI version 5.x are not going to support 1 gen switch

this info its confirm and the clients should buy gen 2 hardware to go for ACI version 5.x?

Hi @CSCO12550173 ,

I would STRONGLY RECOMMEND THAT YOU DO NOT UPGRADE TO VERSION 5 - at least not untill you replace the spines with 2nd gen switches.

Now TBH - you MIGHT get away with it, but you should do a google search for "ACI Version mismatch Alert" (include the quotes) and you'll see ONE problem that might occur (your contract to allow SSH suddenly changes to a contract that allows ALL traffic)

Hi RedNectar, hope you are doing well, thanks a lot for the answer 

so if that is going to happen for the filter, so maybe other behavior could happen after the upgrade

maybe those 1gen devices could take the change to version 5, but considering this unexpected behavior

could result in something worse.

thanks for your info and time, i read your work, its awesome!

best regards
