Technical & Commercial Questions
Payment Gateway Migration FAQs
Answers to the most common questions from CTOs and product leads about migrating legacy payment systems to modern blockchain gateways.
A standard migration for a single payment rail (e.g., credit card processing) takes 2-4 weeks from kickoff to production. Complex, multi-currency deployments with custom settlement logic average 6-8 weeks. We provide a detailed project plan with weekly milestones during the initial scoping call.
