No, the customer's charge frequency listed in the migration CSV overrides the subscription rule in Recharge. The charge frequency set for the customer is based on what you include in the migration CSV.

Migrated customers can maintain their existing pricing and charge frequency, even if these settings have changed for new customers once you migrate to Recharge. For example, if a customer is set to be charged every two weeks in your old subscription platform, but you only have monthly frequencies set up for the product in Recharge, the migrated customer can keep the previous frequency of every two weeks.
