Hi Team,
In regards to MSO upgrade, I have been referring some documentation of Cisco and I did not get the exact answer. Please assist -
We are planning ACI Fabric Upgrade(3 APIC, 2 Spine, 6 leaf, 3-node MSO).
APIC - 4.2(1j)
Spine/Leaf - 14.2(1j)
MSO - 2.2(2c)
Target Firmware - 4.2(7f)
I wanted to know, whether MSO upgrade is the first task or we can simply upgrade entire fabric and then MSO in the last.
I did not find specific recommendation in the official upgrade guide.
Solved! Go to Solution.

With your MSO running 2.2(1) or later, there's no longer any dependency on the corresponding APIC version - so you can upgrade them independently (any order). MSO 2.2+ is "APIC version aware" and will only deploy features to APIC sites that support them. This is documented in the MSO Install guide. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/aci_multi-site/sw/2x/installation/Cisco-ACI-Multi-Site-Installation-Upgrade-Guide-221.pdf
