Version upgrade

Hi,

Currently we are are using version "BIG-IP 11.4.1 Build 681.0 Hotfix HF8". We are planning to upgrade it to latest version 12.1.1 Hotfix2 released on 11/09/2016.

Here my question is if upgrade it to this version, does it include ASM-Latest Signature File ? which is released on 10/13/2016 or do we need update the signature files separately irrespective to the version.
