Hi,
Plan to upgrade the customer's Mobility Controller / Controller from 8.7.7.1 to 8.12.0.6
I would like to upgrade all devices, Mobility Conductor and Controller, to 8.12.0.6 on the same working windows.
I have no intention of letting MC run the new version and leaving the controller running the older version.
Since the upgrade gap is more than 5 preceeding, after MC upgrades to 8.12.0.6 will it have any issue with upgrading controllers & APs, which are 8.7.7.1 ?

With the introduction of the Long Supported Release (LSR) and Short Supported Release (SSR) terminology in AOS-8 8.10.0.0, a Mobility Conductor running an LSR release supports managed devices running the same release and the three preceding releases. This is considered as N-3 support. This allows a customer to run the latest LSR, the previous SSRs and the previous LSR simultaneously. A Mobility Conductor running an SSR release supports managed devices running the same release and the two preceding releases. This would be considered N-2 support and is the same behavior as the pre-AOS-8 8.10.0.0 MultiVersion support.
Only for the AOS-8.10.0.0 LSR release, AOS-8.6.0.0 is treated as an LSR despite being beyond N-3. As such a Mobility Conductor running AOS-8.10.0.0 supports managed devices running AOS-8.10.0.0, AOS-8.9.0.0, AOS-8.8.0.0, AOS-8.7.0.0 and AOS-8.6.0.0.
