Cisco ASA Failover

I have Cisco ASA 5520 and Cisco ASA 5510 box with IOS ver 8.0 on both boxes. Can I do a Active/Active or Active/standby failover between these two boxes?

Is there any way to use the above boxes to configure high availability?

Re: Cisco ASA Failover

I am currently using Cisco 5520 box as the default gateway for my LAN users, now that I have another 5510 box, I want to use both boxes to configure high availability where my LAN users should have access to network using Cisco 5510 in case of Cisco 5520 failure.

Re: Cisco ASA Failover

To accomplish that you have to configure failover betweent these two ASA's and it won't be achieved till the time both hardware and software is same. Please read configure failover document in which complete requirement of failover is written.

No, It won't work, for failover you need to have same hardware and software on both the firewalls.
