Which of the following is NOT recommended for clients who are migrating customer data?

Migrating existing customer data effectively is crucial for a seamless transition to Stripe. The practice of migrating existing customers before bringing new customers onto the platform is not recommended mainly because it can create inconsistencies and confusion. This approach may lead to scenarios where new customers cannot be onboarded or are incorrectly informed about the status of existing accounts, especially if the migration process takes time or encounters issues.

Instead, it is generally better to perform the migration in such a way that new customers can be onboarded simultaneously or shortly after existing customers are migrated. This approach allows for a smoother transition and ensures that the system remains consistent and functional for all users. It helps avoid potential disruptions and provides a unified experience.

Utilizing automated tools for data mapping and transformation, testing the migration process in a staging environment, and backing up customer data before migration are all recommended best practices that help ensure data integrity, minimize risks, and streamline the migration process. These measures contribute to a successful migration strategy.
