Hi Jopeti,

since you have two firewalls in failover, you can follow this doc for zero-downtime upgrade, its the best practise:

Hope this helps.

Hi Varun,

Thanks for your response.
My current version is 7.2 so can I upgrade to latest 8.2 or 8.3?
Is my RAM and all support for that?

Hi Varun,

The below doc have all information.
I have one doubt, My current configuration which is in version 7.2 will lead to any problems after upgraded to 8.2? like NAT and ACL cli commands will be changed.
I guess the NAT and ACL commands will be changed in version 8.3 not in 8.2


Jopeti.

Hi Jopeti,

Yes you are absolutely correct, upgrading to version 8.2 would not change any nat or acl configuration, it changes only when you upgrade to 8.3 or later version.

Let me know if you need any info.

Thanks,

Hi,

What is the latest IOS supported on ASA 5520? 

Does ASA 5520 support 9.2.x?
