Upgrade fortimail in HA active-passive
Hi,
We need to update Fortimail which is in an Active-Passive HA architecture, but we don't know if we should upload the firmware image to the Primary Device and this Primary Device is automatically updated itself and the Secondary unit likewise similar to FortiGate with this architecture. Or on the contrary, we must update the Secondary Unit manually, set this unit as Primary and update the unit that was previously primary.
Could you please resolve this doubt?
Thank you all.
Best regards.
