CMS Migration for Businesses That Have Outgrown Their Platform

We help businesses migrate from outdated, restrictive, or unsuitable CMS platforms to modern solutions including Shopify, WooCommerce, WordPress, Magento, and custom applications. The same signals apply to any business whose current platform is limiting growth, regardless of industry.

Our CMS migration practice covers website and ecommerce data migration, platform replatforming evaluation, migration combined with UX redesign, legacy system modernization, headless and API-driven architecture, and the integration development that connects a new platform to the ERP, CRM, and marketing systems a business already runs.

We work with ecommerce brands migrating from restrictive website builders to Shopify or WooCommerce, jewelry retailers needing diamond inventory and configurator support during migration, and manufacturing and B2B companies moving from legacy systems to platforms that support dealer portals and ERP integration.

Every migration begins with a platform and website assessment: current CMS limitations, content and functionality inventory, and business requirements, because the right destination platform depends on what is actually constraining the business, not a default recommendation.

From content and product data migration with full SEO preservation to headless commerce architecture for businesses outgrowing every standard platform, we manage the migration from planning through launch and post-migration support.

Since 2007, Keyideas has delivered CMS migrations to Shopify, WooCommerce, WordPress, and custom platforms for ecommerce and B2B clients across the United States, United Kingdom, and Australia.

Services That Align With CMS Migration

  • A CMS migration is often the right opportunity to overhaul an outdated website at the same time. Our web design and UX practice combines the migration with a visual and conversion redesign, delivered by one team.
  • The destination platform determines what marketing infrastructure is possible. Our Klaviyo, SEO, and digital marketing practices configure the retention and acquisition tools the new platform supports.
  • For businesses needing ongoing development beyond the migration itself, our offshore development service provides a dedicated resource rather than a project-scoped engagement.

Cities Where We Deliver CMS Migration

  • In New York, Los Angeles, and Miami, we migrate ecommerce and jewelry brands from restrictive platforms to Shopify, preserving diamond inventory data and supplier integrations.
  • In London and Sydney, we migrate manufacturing and professional services businesses from legacy CMS platforms to WordPress and WooCommerce with ERP integration and improved SEO architecture.
  • In Bengaluru, our CMS migration practice supports global businesses replatforming from India for international ecommerce and content markets.

Benchmarked Against Leading Enterprise Technology

We benchmark every CMS migration against the assessment, data integrity, and SEO preservation standards of well-managed replatforming projects.

What We Build With CMS Migration

From website and ecommerce CMS migration to platform replatforming, legacy CMS modernization, headless architecture, API integrations, SEO migration, and performance optimization, we build migration solutions around your existing technology, business requirements, content structure, and long-term growth goals.

Website CMS Migration

Wix, WordPress, and Drupal Migration to Modern Platforms

Content, Structure, and Functionality Preservation

Search Visibility Protection Through the Migration

We move existing websites to a modern CMS while preserving content, structure, functionality, and search visibility, covering common paths including Wix to WordPress, Wix to Shopify, WordPress to WooCommerce, Drupal to WordPress, and custom CMS to Shopify or WooCommerce. Each source platform carries different data structures and export limitations, and we plan the migration around the specific technical constraints of the platform being left rather than a generic migration checklist.

Ecommerce CMS Migration

Product Catalog, Attributes, and Collection Migration

Customer, Order, and Review Data Transfer

Media, Images, and Metadata Migration

We migrate ecommerce stores to a platform that can better support products, customers, orders, integrations, and future growth, transferring products and product attributes, categories and collections, customers, orders, images and media, reviews, content and blog posts, and URLs and metadata. Every category of migrated data is validated against the source platform before it is committed to the destination, because an ecommerce migration that loses reviews or order history damages customer trust.

CMS Replatforming

Requirements Evaluation Before Choosing a Destination

Shopify, WooCommerce, Magento, WordPress, or Custom

Aligning the Platform to Actual Business Requirements

When an existing platform is no longer suitable, we help evaluate requirements and move to a platform better aligned with the business, whether that destination is Shopify, WooCommerce, Magento or Adobe Commerce, WordPress, a custom Laravel application, or a headless commerce architecture. The evaluation is based on the specific limitation driving the replatforming decision, ecommerce capability, content flexibility, integration depth, or custom workflow needs, rather than defaulting to whichever platform is currently most discussed.

CMS Redesign and Migration

UX/UI Redesign Combined With Platform Migration

Mobile-First Development and Conversion Optimization

Website Restructuring, Navigation, and Advanced Search

A CMS migration is often the right opportunity to overhaul an outdated website at the same time, and we combine migration with UX and UI redesign, mobile-first development, conversion optimization, website restructuring, improved navigation, advanced search and filtering, and custom functionality. Doing both together is more efficient than sequential projects months apart, because the same content, templates, and testing effort serve both the platform change and the design improvement.

Legacy CMS Modernization

Legacy System Migration and Custom Application Modernization

API Development and Third-Party Integrations

Cloud Migration, Database Migration, and New Frontend Development

Older CMS platforms can become difficult to maintain, integrate, and secure, and we help businesses modernize legacy systems and move toward scalable architectures. This includes legacy CMS migration, custom application modernization, API development, third-party integrations, cloud migration, database migration, and new frontend development, addressing the accumulated technical debt of a platform that was appropriate a decade ago but has become a genuine operational liability today.

Headless and API-Driven CMS Architecture

Separating Content and Commerce Backend From the Frontend

Flexible Digital Experiences Across Channels

API-First Architecture as the Migration Destination

Businesses are increasingly separating their content and commerce backend from the frontend to create more flexible digital experiences that a monolithic CMS cannot deliver. We build headless architectures where the CMS or commerce platform manages data and business logic while a custom frontend, often React or Next.js, delivers the actual user experience, giving businesses design freedom and performance characteristics that a traditional, tightly coupled CMS cannot match.

AI-Ready CMS Platforms

AI-Powered Search Integration for Product and Content Discovery

Personalization Driven by Customer and Behavioral Data

AI Content Generation Within the CMS Workflow

Businesses are looking for CMS architectures that can integrate AI-powered search, personalization, content generation, and customer experiences rather than platforms that require bolting AI on as an afterthought. We choose and configure migration destinations with this in mind, verifying that the platform’s API and data model actually support the AI-powered search, personalized product recommendations, and content generation tools the business plans to add, rather than discovering the limitation after the migration is already complete.

Omnichannel Content Architecture

Content and Product Data Across Websites and Mobile Apps

Marketplace and Third-Party Channel Distribution

Single Source of Truth for Multi-Channel Content

Modern CMS platforms increasingly need to deliver content and product information across websites, mobile applications, marketplaces, and other digital channels rather than serving a single website in isolation. We architect the migrated platform’s content and product data model to serve as a single source of truth that can feed multiple channels, avoiding the duplicate data entry and inconsistency that occurs when a business manages the same product information separately across several disconnected systems.

API-Based Integration Architecture

ERP, CRM, and PIM Integration Through the New Platform

Inventory, Payment, and Marketing System Connectivity

API Architecture as a Core Migration Deliverable

APIs are becoming a critical part of modern CMS architecture, connecting websites with ERP, CRM, PIM, inventory, payment, and marketing systems that a legacy or restrictive platform’s closed ecosystem could not support. We treat this integration architecture as a core part of the migration itself, not a phase two project addressed after launch, because a migration that reproduces the previous platform’s integration limitations has not actually solved the problem that justified the migration.

Performance-Focused Replatforming

Website Speed and Core Web Vitals Improvement

Mobile Experience Optimization During Migration

Conversion Rate Improvement as a Migration Outcome

Businesses are using migration projects to improve website performance, mobile experiences, Core Web Vitals, and conversion rates, treating the platform change as the opportunity to fix performance problems that have accumulated for years rather than simply moving the same performance issues to new infrastructure. We benchmark the current site’s performance before migration and verify the new platform meets defined Core Web Vitals and conversion targets before considering the project complete.

The CMS Migration Process From Assessment to Launch

Platform Assessment and Migration Strategy Development

Data Migration, Integration Development, and SEO Migration

Testing, Launch, and Post-Migration Support

Every CMS migration follows the same disciplined process regardless of source or destination platform: a platform and website assessment reviewing current architecture and requirements, a migration strategy identifying the destination and a plan covering data, functionality, and SEO, data migration with integrity validation, redesign and development where required, integration development reconnecting business systems, SEO migration with full redirect mapping, comprehensive testing before launch, and post-migration support to resolve issues after go-live.

Frequently Asked Questions about CMS Migration Services

Questions from business owners considering a CMS migration or replatforming project with Keyideas.

It depends on what your current platform cannot support. Shopify suits ecommerce businesses wanting a scalable, easy-to-manage platform. WooCommerce suits businesses wanting WordPress’s content flexibility combined with ecommerce capability. WordPress suits content-driven businesses prioritizing flexibility. Magento or Adobe Commerce suits larger, complex ecommerce operations. Custom applications suit businesses whose requirements exceed what any standard CMS provides. We assess your actual limitations before recommending a destination.

Yes. We migrate from Wix, WordPress, Drupal, Joomla, legacy custom CMS platforms, and older versions of WordPress, WooCommerce, or Magento. Each source platform has different data export limitations and structural quirks, and we plan the migration around the specific technical constraints of the platform being left rather than applying a single generic migration process to every source.

Not if it is planned and executed correctly. We map every existing URL, implement redirects, preserve metadata, and address technical SEO requirements as a core part of the migration strategy, not an afterthought handled after launch. A properly planned migration can actually improve site architecture and technical SEO while preserving the search equity built on the current platform.

Yes, and it is often the right approach. A CMS migration is frequently the right opportunity to overhaul an outdated website at the same time, since the same content, templates, and testing effort serve both the platform change and a UX and UI redesign, mobile-first development, and conversion optimization. Doing both together in one project is typically more efficient than two separate initiatives months apart.

Yes. Integration development reconnecting existing systems and implementing new ERP, CRM, PIM, payment gateway, supplier, and marketing platform integrations is a core part of our migration process, not a phase two project. A migration that reproduces the previous platform’s integration limitations has not actually solved the problem that justified the migration in the first place.

Our process covers eight stages: platform and website assessment, migration strategy development, data migration with integrity validation, website redesign and development where required, integration development, SEO migration with redirect mapping, comprehensive testing, and launch with post-migration support. Every migration follows this structure regardless of source or destination platform, adjusted for the specific scope and complexity of your project.

A website content migration without ecommerce complexity takes 6 to 12 weeks. An ecommerce migration with product, customer, and order data takes 10 to 18 weeks. A migration combined with a full redesign takes 14 to 24 weeks. A legacy system modernization with custom integrations takes 16 to 28 weeks. Timeline is confirmed after the platform assessment defines the actual migration scope.

A platform and website assessment starts at $3,000 and is the recommended first step for any migration project. Projects start at $5,000 for a Strategic Foundation migration covering standard content or catalog transfer with SEO preservation. Next-Level Growth at $10,000 adds a redesign, integrations, or marketing automation modernization. The Accelerated Competitive tier at $20,000 covers complex ecommerce migrations, headless architecture, or multi-system integration projects. Enterprise Partnership at $3,300 per month provides ongoing platform development.

A senior migration specialist at a US agency bills at $100 to $180 per hour. A UK agency charges £80 to £150 per hour. A typical CMS migration project costs $30,000 to $90,000 at a US agency. The same project at Keyideas falls within our $5,000 to $20,000 project tiers.
