I have been delaying an upgrade past 8.2.5 because it is stable and I didnt feel like learning a new way of doing NAT because of the way the code was changed. What is forcing me to go down this path is that I need to be able to let protocol 41 pass through the firewall which doesnt work in 8.2.5 and is what is making me look at 8.3 or 8.4
I know that I will have to install a memory upgrade on both my lab 5505's before I can install the upgraded binary. Will be ordering that in the next few days.
Any suggestions on going to 8.3 or 8.4 based on the reason for the upgrade ? I had been told by TAC to stay away from 8.3 but never got a good reason for that. My lab config (i.e. home ASA) is pretty straight forward (no SSL or IPSEC config), so I would hope it would go fairly smooth. I had heard a lot of horror stories early on but wanted to see how things had been going for everyone with the later versions of code.
