8.4 upgrade

[Josh Sprang]

I am planning on rolling out 8.4 to all my customers who are currently running 8.2.5. Can anyone provide feedback on 8.4 as to which release is the most stable?

Right now I am leaning towards 8.4.2.

Also if anyone can share with me bad bug experience with 8.3 , like the nat exempt unidirectional bug, that would be helpful.

Thanks much

Josh,

I have been upgraded some customers from 8.2(1) to 8.4(3), the only think I can point is:

* When you have a rules where you allow a traffic from specific network/ip, the version 8.4 doesn't translate it well.

* Review all rules one by one.

I did a a 5 customers and the must common problem was missing some rules

That's it.

regards.

I'm running 8.4.3, 8.4.4 and 8.4.4.1 without bigger problems. Plan some time to clean up the NAT-config after the upgrade. The internal upgrade-script of the ASA produces quite a mess if your NAT-config is more complex then just internet-access.
