Hi,
In 8.4 nat, there is nothing as dynamic policy nat rules , static nat rules, regular Dynamic PAT rules. There are only two types of Nat rules, Manual Nat and auto nat. If you do "show run nat", you would see the manual nat section first and then the auto nat section, the order is first manual nat is hit, top to bottom and then it moves to auto nat top to bottom.
Its just that when you migrated the config, the software converted them into those syntax. Although you can right a nat statement in both way if you want, like:
object network obj-10.1.1.1
host 10.1.1.1 ------------------------------> AUTO NAT
nat (inside,outside) dynamic interface
nat (inside,outside) source static obj-10.1.1.1 interface -----------------------------> MANUAL NAT
So the order of preference ony depends upon whether you have configured auto or manual nat.
