Hi Azizur,

You can use the following link to upgrade the ASA pair:

http://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-next-generation-firewalls/111867-asa-failover-upgrade.html#zerotime

May I know what is the current version of the ASA and to which version are you planning to upgrade ?

Regards,

Aditya
