Spine/Leaf version compatibility with APIC version

[ftsns]

Hi,

We need to bring the APIC cluster (APIC-SERVER-M2) 4.2 to 6.0. And Switches 14.2 to 16.0. 

My concern is what should we upgraded first. APIC cluster or Switches ?

Thanks

Hello @ftsns 

As per Cisco's best practices, It is generally recommended to upgrade the APIC cluster before upgrading the switches.

Please do consider that proper planning, testing, and a rollback plan are essential for a successful upgrade.

Wish you very best!

Hope This Helps!!!

Hello @ftsns ,

Upgrade the APIC servers first. For the switches, make sure to upload both 32- and 64-bit firmware versions.
