IOS Update Problem

mehmoodch — Mon, 11 Mar 2019 23:35:31 GMT

Hi,

I have CISCO 5510 firewall running with IOS ASA821-k8.bin.

My company has purchased another ASA5510 with IOS ASA843-k8.bin

We need to run both firewalls in Active/Standby mode.

If I upgrade the IOS of old firewall to ASA843-k8.bin the the running configurations does not work properly

It does not pick the network objects and NAT rules as they are configured with OLD IOS and running.

Or if I restore the configurations of old firewall at New ASA the result is worst. Even firewall with new IOS does not show any Access Rule and NAT rule and does not supprt network objects

Any help to solve this issue

Thanks

Hi,

The versions are different and the configs ar different.

You search google with the keywords cisco 8.3 asa youtube.

You will get a video showing the steps to configure in ver 8.3.

Hi Mahmood,

Either you can make your bothe ASA's running in ASA 8.25 OS or Upgrade to 8.4.3 OS.

If you make 8.25 then you will not have much congiguration changes. But if you make it in to 8.4 there are few changes es[ecially with the NAT rules.
