Upgrade IOS on ASA 5510

[NetSupport DPS]

I am upgrading an ASA 5510 from ASA822-k8 to ASA841-k8. I know I have to upgrade the RAM to 1GB from 256MB, but was wondering if it is a direct upgrade, or do I have to step through some of the 8.3(x) versions?

you can go straight to 8.4.1

Hi,

I guess there are some syntax changes from 8.3.x onwards for static nat and global configs. Please make sure you are aware of that.

Upgrading the Software

Note You can upgrade from any previous release (if available for your model) directly to 8.4. If you are upgrading from a pre-8.3 release, see the Cisco ASA 5500 Migration Guide for Version 8.3 for important information about migrating your configuration to release 8.3 or later.

Upgrading from some releases may have consequences for downgrading; be sure to back up your configuration file in case you want to downgrade.
