PAN-OS HA UGRADE PATH

Hi All, Please I'm upgrading a palo alto firewall in HA mode remotely, I'm having some issues with remote access and for me not to loose access and be able to finish my upgrade is it ok to upgrade the Passive first before failing over to the passive and then upgrade the Active ?

@E.Annobil,

Yes, you can upgrade the passive unit before failover over the traffic and upgrading the previously active unit. This is common and how the vast majority of upgrades are performed since it gives you an easy path to immediate revert should the upgraded unit have any immediately noticeable issues.
