I wanted to see if it was possible to use a config file from one ASA, a 5545 in this case, on a different one that's intended to be used in a lab environment. The second ASA is a 5508 in this case.
Secondly, is it possible to edit a config before restoring it to the secondary appliance? I'm fairly new to this, and I don't mind doing it bit by bit, but there's a lot of objects and rules to recreate.
Solved! Go to Solution.
Yes you can copy configuration from one ASA to another. You should try to ensure the ASA code is similar on the 5508 to the 5545 as some syntax may have changed, but in the main you should be ok.
Yes you can edit the configuration, you will just be copying and pasting, so you can edit object names, ACLs, interfaces etc.
Sorry, one bit I wanted to clarify:
In this case where you mention copying between ASAs, is it possible that I could do so via the import/restore feature within the ASDM application?
I never use the ASDM, I prefer the CLI, but I see no reason why you could not import via ASDM. You should be careful though if the ASA firmware is different, the syntax may have changed between versions for some of the commands or interfaces maybe different - this may cause the import to fail.
I would personally copy and paste only the sections required rather than imported the entire config.
That's an excellent point. As I've been looking at the steps that would be needed I've found they're differing versions of firmware.
I'll try and copy the pieces I need to speed things up instead. Is any special syntax needed in those cases or can I just copy an entire section for say, network objects or access lists, and paste it into the other ASA so long as it's in config mode?
