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.
