Complex mysql insert query - mysql

Question

I am attempting to write a migration script (between 2 versions of a program) to populate the phppos_permissions_actions table.
The rule for populating is: "If the user has permission for the module (based on phppos_permissions), then they are granted all action permissions for that module. (Which can be looked up in phppos_module_actions)".
I am trying to write a query or a set of queries that makes the following rule happen. Could someone guide me in the right direction? Below is my schema

Does
insert phppos_permissions_actions (module_id, person_id, action_id)
select distinct
phppos_permissions.module_id, phppos_permissions.person_id, action_id
from phppos_permissions
inner join phppos_modules_actions on phppos_permissions.module_id = phppos_modules_actions.module_id
order by module_id, person_id
solve your problem?
