Is ASA 5520 and ASA 5525 share the same OS?

[loc.nguyen]

Hi,

I try to upgrade IOS for my ASA 5520. I did not find any OS for it in cisco website.

Can I use asa9-14-3-13-smp-k8 which is for ASA 5525 for my ASA 5520?

Note: I tried to transfer file from my laptop to the ASA 55520 using ASDM, but it fail. That makes me think I can not.

Pls advise.

Thanks

Loc

IOS ver9.14 is not applicable to 5520, the highest version of 5520 is 9.1.x

-----

ASA 9.12(x) was the final version for the ASA 5512-X, 5515-X, 5585-X, and ASASM.

ASA 9.2(x) was the final version for the ASA 5505.

ASA 9.1(x) was the final version for the ASA 5510, 5520, 5540, 5550, and 5580.
