Answer
Website replatforming typically takes between 3 to 6 months to complete the migration process. However, the process may take 2 to 20 months depending on complexity and budget requirements. If complex integrations and full customization are needed, replatforming may take at least 6 months, while using a fully managed cloud Software as a Service (SaaS) solution like Shopify with an existing theme without customizations or integrations can take around 8 to 12 weeks.
Timeline estimates should consider factors such as website complexity, content size, and resource availability, with realistic planning that builds buffer time for unexpected delays or issues. If someone promises a complex replatform in 4 weeks, they're either cutting corners or underestimating scope.
