Solved: 9800-40 HA Upgrade from 17.6.4 to 17.9.3

scottsassin · ‎06-16-2023

We are upgrading our 9800-40 HA Upgrade from 17.6.4 to 17.9.3.

Can these versions be upgraded to directly from and to, or is there version steps?

Since this is an HA pair, can these be upgraded one at a time by failing over and upgrading the standby?

Can someone send me the procedure to upgrade them.

Yes, direct upgrade is supported. Please refer page 35 onward of below document for step by step instruction.
Upgrade using GUI is simple and it take care of all the complexities.
