Task 1: Enable Recurring Billing in Your `Cybersource` Account {#rb-subs-migration-1-enable}
============================================================================================

Recurring Billing requires that you have a `Cybersource` account with a properly configured `Token Management Service` (`TMS`) at the transacting MID level and with a configured token vault. In addition, customer tokens from the current provider must be in the `Cybersource` `TMS`.

1. To enable Recurring Billing:
2. Verify that you have a `Cybersource` account.
3. Confirm your account has a transacting MID with `TMS` and token vault configuration. See [Migration Prerequisites](/docs/cybs/en-us/recurring-billing/migration/all/rest/recurring-billing-migrate/home-merch/rb-subs-migration-0-prereqs.md "") for details.
4. Verify that customer tokens from the current provider exist in the `Cybersource` `TMS`. See [Migration Prerequisites](/docs/cybs/en-us/recurring-billing/migration/all/rest/recurring-billing-migrate/home-merch/rb-subs-migration-0-prereqs.md "") for details.
5. Contact your `Cybersource` Account Manager to request activation of Recurring Billing for your account.
6. After receiving the confirmation notice, proceed to [Task 2: Integrate with the Cybersource API](/docs/cybs/en-us/recurring-billing/migration/all/rest/recurring-billing-migrate/rb-subs-migration-2-integrate.md "").
