There is a tool out there that will allow you to export it to a CSV. I had a brief look and it needed further understanding. I wasnt sure how much time would be required and I didnt want to waste time unnecessarily.
So instead, what I did as a one-off was log into the FMC with a browser and copy the tables from the browser and paste directly into MS Excel. Once I had all the rules copied into Excel, I simply used Excel to figure out all of the rules needing to be replicated across. Some rules were there that were no longer required or were there because of a previous ASA migration tool that messed up the config etc etc. I used colours and added additional lines in excel to expand on the ACL groups and other groups etc.
Another huge benefit to me by doing it this way is that by the time I got to installing rules for the new firewall, I had learnt most of the config and understood routes and rules placement and reasoning.
Not sure exactly how you would copy the tables from the browser. I must be missing something.
But even if I could I't doesn't seem more useful/feasible than getting it from the cli and then manipulating it out to a usable format.
Did you do this in a for a smallish environment?
