Pre-Requsites to Upgrading

Many models of the ASA require a memory upgrade prior to upgrading the ASA to version 8.3. Brand new ASAs from the factory (manufactured after Feb 2010) come with the upgraded memory. However, if your ASA was manufactured before February 2010, and is one of the models below requiring a memory upgrade, then you will need to purchase the memory upgrade part prior to installing 8.3 on your ASA.

Platform	License	Pre-8.3 Memory Required	8.3 Memory Required	Memory Upgrade Part Number
5505	Unlimited (inside hosts=Unlimited)	256 MB	512 MB	ASA5505-MEM-512=
5505	Security Plus (failover=enabled)	256 MB	512 MB	ASA5505-MEM-512=
5505	All other licenses	256 MB	256 MB	No Memory Upgrade Needed
5510	All licenses	256 MB	1024 MB	ASA5510-MEM-1GB=
5520	All licenses	512 MB	2048 MB *	ASA5520-MEM-2GB=
