The problem is we would like to have no downtime of the Firewalls.</P><P></P><P>I have an idea of replacing the the Standby first with a 5550 and bringing on line with the Primary 5520. Then failing over to make the 5550 Primary and the 5520 Secondary. Then upgrade the Secondary 5520 to a 5550. Leaving us with a succesfull upgrade to ASA5550's and no down time.</P><P></P><P>Has any one done this or can see an issue with this type of upgrade path.</P><P></P><P>Many thanks</P> Tue, 26 Mar 2019 00:44:05 GMT https://community.cisco.com/t5/network-security/asa-hardware-upgrade/m-p/1400328#M724007 Ian Beck 2019-03-26T00:44:05Z Re: ASA Hardware Upgrade https://community.cisco.com/t5/network-security/asa-hardware-upgrade/m-p/1400329#M724013 <HTML><HEAD></HEAD><BODY><P>The hardware (model) has to be identical in order for failover to work.</P><P></P><P>I suggest that you schedule some down time and get this done.</P><P></P><P><A class="jive-link-external-small" href="http://www.cisco.com/en/US/docs/security/asa/asa80/configuration/guide/failover.html#wp1155967">http://www.cisco.com/en/US/docs/security/asa/asa80/configuration/guide/failover.html#wp1155967</A></P><P></P><P>-KS</P></BODY></HTML> Wed, 20 Jan 2010 13:17:24 GMT https://community.cisco.com/t5/network-security/asa-hardware-upgrade/m-p/1400329#M724013 Kureli Sankar 2010-01-20T13:17:24Z Re: ASA Hardware Upgrade https://community.cisco.com/t5/network-security/asa-hardware-upgrade/m-p/1400330#M724017 <HTML><HEAD></HEAD><BODY><P>Rats !</P><P></P><P>Thanks</P></BODY></HTML> Wed, 20 Jan 2010 14:05:08 GMT https://community.cisco.com/t5/network-security/asa-hardware-upgrade/m-p/1400330#M724017 Ian Beck 2010-01-20T14:05:08Z Re: ASA Hardware Upgrade https://community.cisco.com/t5/network-security/asa-hardware-upgrade/m-p/1400331#M724025 <HTML><HEAD></HEAD><BODY><P>Just had a thought, even if the 5520 is accept, for model differenences, identical.</P><P></P><P>That is we have a 4GE-SSM in the 5520.</P><P></P><P>Thanks</P></BODY></HTML> Wed, 20 Jan 2010 14:21:04 GMT https://community.cisco.com/t5/network-security/asa-hardware-upgrade/m-p/1400331#M724025 Ian Beck 2010-01-20T14:21:04Z
