Hello,<br />
<br />
I am looking into updating our ASA 5515 firewall. &nbsp;It is an active/standby configuration. &nbsp;I was looking at the upgrade tool built into the asdm and was hoping to use that. &nbsp;Does anyone have experience using the asdm for updates, do I just run through the wizard and it does it all? &nbsp;Can i perform this during the day with very little downtime? &nbsp;Which ASA should I upgrade first, active or standby? &nbsp;And I am on ASA version 9.1.2, should I go straight to the newest 9.5.1? Any help is appreciated. <br />

Which ASA should I upgrade first, active or standby?  And I am on ASA version 9.1.2, should I go straight to the newest 9.5.1? Any help is appreciated.

Cisco ASA update using ASDM in Active/Failover

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
