Hello Community,

I have an Chassis based S-Series configured as an VSB, running EOS

Primary due to an SNMP problem (Switch doesnt respond reliable to SNMP querys) I would like to do an HAU upgrade to, but the HAU Key told me "(HAU incompatible)".

Is it possible to update in multiple "HAU compatible" steps, to prevent a full reboot of both cassis?

HAU upgrades are only possible when the HAU key (listed in each version's release notes and the firmware on the switch with "dir") matches, and it's a hard break, there are no overlapping versions that have two HAU keys. https://community.extremenetworks.com/extreme/topics/7100_s_n_series_high_availability_upgrade_hau_v... has an older list, but it looks like you're out of luck.
