Upgrade order?

[john sloan]

When upgrading from 8 to 8.5.6, do I do the c370s (Email Security appliances) or the M670 (Content Security Management Appliance) first? Or does it not matter?

Thanks in advance!

You should do the SMA first, then the ESA(s), and then re-associate the ESA(s) to the SMA as needed.
