ASA5585-S20-K9 from 8.2 to 8.4 upgrade memory required?

Have an ASA5585-S20-K9 and I need to get from 8.2 to 8.4.  Currently has 4 GB of memory, but it needs to be improved to a minimum of 8GB.   I searched high and low for a kit to upgrade for the 5585 but do not come with anything.  Found for the 5540 and below, but there must be something special about the 5585 s I can't find anything.

If anyone has an idea on what I need to get to level set memory, it would be appreciated.

Hello Chris,

According to usually at the documentation below, we can see that ASA 5585 comes with 12 GB of memory. Please see the 5585-s20 ASA data sheet below.

Firstly, please note if you are running 8.2.x code on your ASA5585-s20. It seems that ASA 5585 SSP-20 will watch 4 GB of RAM which is expected for the 8.2 software with no support for 64-bit (so it cannot process more than 4 GB of RAM in the application of the ASA). If you switch to 8.4 example software, which supports 64-bit, all of the 12 GB of RAM will be used.

Also on the way to upgrade from 8.2 to 8.4.

Things to remember: -.

Upgrade from 8.2 to 8.4 ASA, is NOT a minor update. There are a few things that are need to keep in mind:
1. NAT statements are completely different.
2. the IP addresses used in ACL are real IP (not translated)
3. it is recommended that you take the time to stop for this upgrade.

Things to do before the update: -.
> Disable NAT control over the two ASA.
> Check the memory required for the upgrade.
> Take configure Backup.
> Follow the upgrade path as mentioned below.

Things to do after the update: -.
> after reclassification of 8.2.x to 8.4.7, you must check the start config error.
> present the startup-config errors, it will show that NAT and ACLs statement has not been
migrated, so we can manually configure these instruction.
> arp permit-nonconnected.
> Of 8.4.7 9.1.4 or 9.1.5, you can migrate directly.

Hope this information helps you.

Kind regards
