Find an older image

[Bob Greer]

Hi there,

Thanks for reading.

I've got licensed ASA 5520s, 5510s and a 5505 with ios 8.2 and newer.  I'm running simulation software (GNS3) which doesn't seem to like newer ASA images.  How do I legally source and older image using my licensed hardware?

Thanks again,

Bob

You can run 8.4 on GNS3. Steps are outlined here:

If you have the licensed software you can load your image into GNS3 and work with it virtually there.

Thanks for writing in Marvin.  I'd come across this fix previously.  I was falling short on generating the INITRD and KERNEL files.  Once I rememdied that, the link you supplied was spot on.
