Now one more important thing about upgrading. So, for example, if we bought the ASA5520 before February 2010, we first need a memory upgrade and then we can go for an upgrade. Internal Flash Memory (Default Shipping) 1, 2Īfter Feb.

There is another thing we must take into consideration when planning fro an upgrade – memory requirements. Of course, with the appropriate memory upgrade. One thing I would like to point here out: the old platforms (5505, 5510, 5520, 55), contrary to what some Cisco (?) engineers said to me, *can* run the new code, as stated in the table above. Here is the matrix from that can help us determine which version can be run on which platform:ĪSA 5512-X, 5515-X, 5525-X, 5545-X, 5555-XĪSDM 6.0(2) and later. We have to know this compatibilities, because trying to upgrade 5520 from 8.2 to 8.7 would be a horrible idea. The new versions of ASA appliances, called “ The ASA Next Generation Firewall”, the ones with an “X” in its name run only 8.6 or 9.x, except for the 5585-X which van run older code, and the “old guys”, 55xx can run 7.x, 8.0, 8.1, 8.2, 8.3, 8.4 and 9.x, but cannot run 8.5, 8.6 or 8.7. The ASASM (“ ASA Service Module”) can only run 8.5 or 9.x.

For example, “ Cisco ASA 1000V cloud firewall” can only run 8.7 version.

Not all ASAs can run any version of code. Cisco ASA now days can run three generations of code, depending on the hardware platform and memory installed.
