Why Consider eCommerce Platform Migration?

B2B companies pursue eCommerce replatforming to support business growth, drive digital innovation, and deliver on customer demands. Common triggers include:

• Needing better scalability to handle increasing products, users, or markets.
• Improving performance with faster site speeds and mobile upgrades.
• Addressing feature gaps that limit personal touches, multilingual support, or advanced pricing.
• Meeting integration needs with ERP, CRM, and PIM tools.
• Elevating the customer experience through modern UX and self service features.
• Achieving better cost efficiency by reducing maintenance and development expenses.

PIM for eCommerce helps support scalable migrations by bringing data together and enriching product information across all channels.

When is the Right Time to Replatform?

Your business signals when to start an eCommerce migration. Pay attention to:

• Hitting platform limitations that prevent growth or new features.
• Accumulating technical debt that creates maintenance bottlenecks.
• Facing poor integration between systems.
• Managing rising costs for licensing and support.
• Launching new business models like D2C, subscriptions, or international sales.

Conduct a thorough technology audit and platform assessment to align replatforming with strategic goals. Prioritize business alignment and lead with strong change management to secure internal buy in.

Types of eCommerce Replatforming Projects

You can approach eCommerce replatforming in different ways, depending on your needs:

• Migrate directly from one platform to another using a platform to platform approach.
• Use a phased migration to minimize disruption by transitioning in stages.
• Move from a monolithic platform to headless commerce or composable commerce to unlock agility.
• Shift legacy infrastucture into a SaaS migration model to lower costs and simplify scaling.

Modern B2B organizations often combine tech stack upgrades with these migration strategies to future proof their ecosystems.
