Changing Fortigate 200B firewall from HA Master to Standalone - Possible Issues
I was going to upgrade a 200B firewall this evening at one of our branch offices. Going from v4.3.12 to v5.2.6
This is a single firewall that was at one time part of an active-passive HA pair. The slave had been removed a while ago but The HA config on this FW, says that it is still MASTER and that HA Config is 'Active-Passive'. I was concerned that if I applied an upgrade of the firmware and did a reboot, this could cause a possible failure or crash. Could it have?
My main question: How do I set the firewall to 'STANDALONE' without impacting the current config(attached)? Is it as simple as going into HA Config and changing the Mode from Active-Passive to Standalone and hitting OK?
Of course my main concern is doing something improperly that brings down the firewall.
