asa5520 image upgrade

Hi

I have asa5520 on version: 7.2(4)

#sh ver

hardware:  ASA5520, 512 MB RAM, CPU pertium 4 celeron 2000MHz

Internal ATA compact Flash, 64MB

BIOS Flash M50FW080 @oxffe00000, 1024KB

#dir

62947328 bytes total (19222528 bytes free)

Could any expert advice me, if I want upgrade to version 8, which version I can go, if I do not upgrade the memory?

the box is configure only for firewall, not vpn or fancy stuff.

Any comments will be appreciated

Thanks in advance

Version 8.0.5 would be the one you should go as version 8.2.x will require more memory.

Please also be advised that since you only have 64MB of internal Flash, it is recommended that you don't have multiple images stored on the ASA. Here is the doc for your reference:

Hope that answers your question.

No, it shouldn't reduce the performance with version 8.0.5.

Thanks for the reply.

If I upgrade to version 8.0.5, can I have similar performance as current (v7.4)? do I will have performance reduced because the image used more memory?

I have no any performance issue at current time.

Please advice

regarding to the 8.3-Release-notes, the higher memory-requirements start with v8.3:

I also have a couple of older 5520 with 512 MB running on 8.2x without problems.

You're right, Karsten.

Memory upgrades are only required for customers moving to ASA 8.3+. I've upgraded lots of non-memory-upgraded ASA 5520s to 8.2(x).
