Our customer wants to upgrade his ASA5520 from 7.2 to 8.x. He has quite a big config and uses lot of features. eg.
a/s failover, subinterfaces, ~70 VPN tunnels (ssl and ipsec), bunch of grouped object's, some policy-maps, lot of ACL's, NAT exemptions etc.....
Does anyone have some best practice Experiences?
Are there a lot differences in the config Syntax to the 8.x ?
