Firmware upgrade

I am in a plan of performing a firmware upgrade to SFOS 19.5.4 MR4-Build718. I was wondering if I do the upgrade to the primary firewall will it be reflected to the secondary (HA, passive active)? or should I log in locally and perform the upgrade.

Thank you :)

Auxiliary will be upgraded first, then primary right after that. Cluster will always have the same firmware.
