Hi,

Cisco does not have a tool available for this, though I'm not sure if you could find a 3rd party one.

The conversion should be pretty straight-forward as the code is fairly similar. PIX 6.x commands will line up with FWSM 2.x, whereas PIX 7.x commands will line up with FWSM 3.x.

One major difference to keep in mind is that physical interfaces on the PIX will become VLAN interfaces on the FWSM.

Here are some links to the command references, which should help you work through the migration:

PIX 6.x Command Reference:

PIX 7.x Command Reference:

FWSM 2.x Command Reference:

http://www.cisco.com/en/US/docs/security/fwsm/fwsm23/command/reference/fwsm_ref.html

FWSM 3.x Command Reference:

Hope that helps.

Please keep in mind some fundamental differences between FWSM and PIX. For example FWSM needs an ACL applied in the incoming direction on EACH vlan interface to pass traffic. There are other caveats also based on your current PIX config. VPNs are not supported on FWSM (except for Management).
