ASA 5520 Upgrade Question

Currently running version 7.0 (8). Going to lease a ASA (max flash & DRAM) so that I can upgrade.

I plan on upgrading the leased ASA to the latest & greatest version, my question is what version do I want to use ?

Re: ASA 5520 Upgrade Question

Hello,

I would suggest the 8.0 or 8.2 train unless there is a specific feature in 8.3 that you need to use. The reason for this is that there are very significant changes to the way NAT and ACLs are configured in 8.3, as well as the requirement for a memory upgrade. Here are the release notes for each so you can take a look at features and open caveats in each:

8.0(5):

8.2(3):

8.3(2):

Re: ASA 5520 Upgrade Question

Just purchased 512MB Flash & 2GB DRAM for the current ASA so I don't think future upgrades will be a problem, thanks for the input !

Re: ASA 5520 Upgrade Question

One feature in 8.3 that I wished I had once upon a time was the capability to clear a DF bit.  Used to be that only a router could do it.
