Convert to FW4?

With the switch to FW4 what packages do I have to remove To remove reminants of FW3?

Also what packages do I need to add in or will they all be auto selected in selecting firewall4 in the base system?

guess I need to disable the following?

PACKAGE_kmod-ipt-conntrack
PACKAGE_libxtables
PACKAGE_kmod-ipt-nat
PACKAGE_kmod-ipt-core
