Hi,

There is no direct upgrade to 8.6 from your current version. You will need to use a two stage process for the upgrade. You will need to either upgrade to a 7.1.5 or to a 8.0 (3) before you can go to 8.6

Please look at the compartibility matrix here..

Alos, review the release notes as there are several notes for some MCS models and their limitations.

HTH,
