Check ASA 8.2.5 config compatibility to 8.3.1

[PiEich]

Hi guys,

I tried to upgrade a 5540 ASA from 8.2.5 to 8.3.1. When I did I got a huge amount of errors in NATs as per the unidirectional feature...

Is there an automatic way to check my current configuration to fix all the misconfigurations? This company has a looooooot of NATs and none of them worked :(

After upgrade I got an upgrade_startup_errors file of 30K

Thank you!

You can try feeding them into the converter here:

I've had good results using that tool in the past.

Note you will also need to check the access-list entries to make sure and outside-in lines convert to real IPs vs. NAT addresses.

Will try that, thank you very much!
