platform-migrate and APM

I know the docs say it's not supported for anything but LTM and GTM but I was able to use this successfully for an LTM/APM migration from a vCMP Guest (v12.1.2) to a VE (v12.1.3.4). From what I can tell everything came over (access policies, customization, encrypted pws for aaa, etc.). My question is, is there anything specific that is not supported for using platform-migrate for APM or did I just get lucky?
