Upgrade ASA 5505 from 8.2.5 to 8.3 or 8.4

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.

Thanks,

Ron

I recently looked at this question with a customer who has been running 8.2 and needs to get some features in newer code. We decided that it made more sense to go to 8.4 than to 8.3.
