Migrations are typically completed within 48 hours of payment. We don’t charge a migration fee, but your first month of billing starts after you sign-up… so technically there is a small fee. Downtime is typically under 30 minutes unless you have eCommerce traffic or other transactions happening on your site that we need to take extra care to not lose any data. If that is the case, there may be 2-4 hours of downtime which we can schedule during your non-peak hours.
