LitExtension grants customers a chance to preview the migration result with Free Demo and supports migration with limited entities (20 products, 20 customers, 20 orders and related data) from the Source Store to another desired shopping cart. Only the first 20 of each entity will be transferred to the new store, not all of them.
Therefore, it’s not that you lose data after demo migration. You’ll have all your data transferred to the new store if you opt for Full Migration.
