hello
am implementing a new ACI fabric from scratch for one of our customers, we have installed the leaf, spine, and APIC
when I checked the BoM of this project I noticed that the APIC is running Software Release 6.0, but all the leaf and spines are running 15.0 software release.
the question is can I upgrade the leafs and spines after I perform the fabric discovery by pushing the new image from the APIC ?? or i should match the software versions of the leafs and spines with the APIC before I perform the fabric discovery??
