The Lightspeed OnSite Help Center includes a comprehensive guide on migrating from OnSite to Retail which includes all of the details you need to import your data, as well as some special considerations to keep in mind. Migrating to Lightspeed Retail comes with many advantages to empower your business, and we'll be with you every step of the way to help. That said, though they both bear the name Lightspeed, Retail and OnSite are different systems and sometimes satisfy your business needs in different ways, so we strongly recommend reading the entire migration guide to ensure the smoothest possible transition.
