Fabric running 3.2, going to discover 4.2 for Multi-Pod

Hi folks,

 

I have a client with their production, single-pod fabric running 3.2(3), the one which can be directly upgraded to 4.2(7q). We are proposing upgrading the production fabric first, then going to introduce the other Pod because it is net-new. The new hardware are being shipped and not ready on-site, however according to the BoM it would be 4.2 anyway, so we figure upgrading the production fabric would be done sooner or later.

 

However, during EoY, they are afraid that upgrading the production fabric. They are proposing if we could introduce the new pod (running 4.2) to the fabric (running 3.2), then only upgrade the production fabric once everything has been migrated to the new pod.

 

Is it possible to discover new hardware with such mismatched versions?

 

P/s: no 5.2 train since their production Spines are not supported.

Hi @tuanquangnguyen 

APIC versions cannot be older then the fabric nodes. In other words, answer to your question should be no.

However, I think a solution might be to upgrade only your APICs to 4.2.7, discover the new pod, migrate to new pod, finish the upgrade of pod1.

 

Stay safe,

Sergiu
