FWSM v4.1 to ASA v9.6.1 on Firepower 4100

Hello,

As you can see in the title, I have to migrate a (huge) configuration from FWSM OS v4.1 to ASA OS v9.6.1 on Firepower 4100.

I found the FWSM to ASA-SM migration tool - which translates the configuration to ASA-SM OS v8.5 - here:

http://www.cisco.com/c/en/us/td/docs/security/asa/migration/fwsm/fwsm2asasm.html

I also know the officially recommended upgrade path from here:

http://www.cisco.com/c/en/us/td/docs/security/asa/asa96/release/notes/asarn96.html#ID-2152-0000000a

There are two problems:

1. I can't boot in place with one of the new ASA images, because I am migrating *both hardware & software version* at the same time.

2. I can't figure out  where the resulting ASA-SM v8.5 configuration from the first link would fit in the table from the second one.

Supposing I can find and will use an old ASA 5550, I still can't figure out with which software version I would have to start the migration with.

Version 8.5 seems to be an odd one, I can't find it here:

Has anyone successfully done this, and if yes, how did you go about it ?

Thank you !
