Last night, I had the most vivid nightmare about failing over ASAs and config was out of sync (like, by years). It's been over a year since we replaced them, and they still haunt my dreams.
SuperSluether@botscailey can't say I've had the pleasure (displeasure?) of working on an ASA. We have Firepowers in the lab and use Meraki for our clients.
@SuperSluether I'm a big Cisco fanboy, but I worked as an ASA and Firepower SME for a number of years and... I just have some residual trauma lol.
