ASA Upgrade from 8.2 to 8.4, disruptive to NAT and ACL's ?

FuturaFutura Posts: 191Member
Hi there, first post in this section of the forum so go easy on me, I have a ASA 5540 at my disposal and currently run 8.2. I have full service contract so no worries there. what does bother me is that I believe the migration to be a little difficult due to NAT rules and ACLS etc. Could any expert take a look at my config and point me in right direction. I really don't see how my NAT rules would be affected by it?


RAS-ASA# sh nat

NAT policies on Interface inside:
match ip inside any outside 192.168.184.0 255.255.255.0

    I only glanced through this, but I'll say that the 8.3 auto-migration wizard doesn't always work well. In a particular case I went from 7.x to 8.2 to 8.3 and it ended up being a disaster. Not everything migrated cleanly, I lost a number of routes and ssh statements, etc.. I had to rebuild some of the config from scratch in a severely-constrained maintenance window. This might not end up being the case for you, but I recommend testing well beforehand.

    DO NOT auto migrate anything 8.2 to 8.3+. I have done a bunch of 8.4 migrations to my internal ASAs and customer ASA. I will always export the build and then analyse the text.

    for the most part it gives me an oppourtunity to really look and go:

    WHY DID THEY BUILD THIS IN ASDM
    WHY ARE THESE RULES HERE THEY DONT DO ANYTHING
    THESE TUNNELS ARE OLD AND WE DONT HAVE THESE VENDORS ANYMORE

    As docrice stated its not just NATs, vpn statements are slightly different with isakmp versions, nats will break of course.
