No, NAT syntax in pre 8.3 and 8.3 and later is different, so you have to configure NAT from scratch

Is it only NAT? or do I have to reconfigure access lists and object groups also?

Hi Experts,<br />
<br />
After a software/firmware upgrade of my ASA5520 (8.25 to 8.43) Firewall, all my NAT rules, ACL's and Object Groups are gone. I red on the internet that something could go wrong with the NAT rules only, but I didn't expect that eveything would be gone.<br />
<br />
Of course i created a backup of the configuration before the update, but I can't restore it on the new firmware version.<br />
<br />
Is there a solution or workaround for this problem? Or do i have to reconfigure the ASA?<br />
<br />
