Conversion Cloud can run alongside an existing conversion tool, but the merchants who get the most out of it consolidate. Rules-based upsell apps do one job. Conversion Cloud handles AI-driven recommendations, customer segmentation, and pre-purchase conversion in a single system, with an analyst tuning it for you.
The path we recommend: keep your current tool live during onboarding, let your analyst benchmark Conversion Cloud against it on real traffic, and sunset the old tool once the numbers are in. You end up with one system, one source of truth, and one person accountable for the results.
