We specialise in complex eCommerce migrations, helping businesses like yours transition from older or limited platforms onto modern, robust systems, without affecting your position in organic search. Whether you’re moving to scale up, consolidating operations, or optimising performance, our experienced team has got you covered.
Our eCommerce migration experience
We migrate stores of all sizes from platforms including:
- Magento/Adobe Commerce
- WooCommerce/WordPress
- BigCommerce
- Shopify (if replatforming or upgrading)
- Custom/Proprietary Platforms
- Marketplace integrations
The most important factor when carrying out a migration is opening up access to improvements without negatively impacting your customers, or your performance in Google search, and that’s at the heart of everything we do.
Discovery & Planning
We’ll take the time to correctly understand your current setup (platform, customisations, theme and any integrations) before working with you to define what it is you want to achieve following your migration, and any technical or business risks that are associated with the changeover.
This will produce a migration roadmap that defines the entire project, along with a timeline, and inventory of all your data, and a risk register that means we’re aware of any potential problems before they happen, giving you an updated website, with none of the messy consequences that can come with a botched migration.
Data & Architecture Audit
Our data review will cover your existing site’s eCommerce data (products, orders, customers), along with site architecture, URL structure, and your existing page structures in order to maintain your search rankings after your site has been migrated. We’ll also identify any custom fields, legacy content or meta data requirements that might affect either your search engine optimisation or the way your site search works.
Theme / Design Adaptation
We can recreate your existing theme on your new platform, or many clients use this opportunity to refresh and update the look of their existing site. This might be through a new theme, or a project to build a bespoke new look for their brand.
Our team is experienced in working with clients to discover what their clients want from an online store, and implementing optimised changes which will improve the conversion rate and user experience of your site.
As part of the process, we’ll provide you with design prototypes that lead to a working theme, along with user testing if required. All our designs offer versatility, functionality, and the responsive design which today’s modern consumers demand.
Data Migration & Integration
We’ll export the data from your old system, clean it and transform it to integrate with your new platform. We’ll set up integrations for payments, shipping, your ERP and/or CRM, and any custom functionality.
By integrating the data from your old platform, we ensure you’re starting from where you left off with your old site. That includes product, order and customer history, and any integrations. We’ll then test it across devices and browsers to make sure it’s all working as it did before.
SEO & Redirects
One of the most important parts of getting a site migration right is ensuring that the new platform maintains your position in search results.
Implement SEO best practices, maintain link equity, set up 301 redirects, fix broken links, manage canonical tags and metadata.
Key milestones: Redirect map, updated SEO metadata, minimized traffic loss.
Testing & Pre-Launch
This phase is designed to ensure that every element of your new site performs flawlessly before going live. Our team conducts rigorous quality assurance (QA) across all key functions, verifying that navigation, checkout flows, integrations, and user interactions work exactly as intended. Security measures are reviewed in depth, performance and load testing are carried out where needed, and we confirm that the site is fully optimised across browsers, devices, and screen sizes. Regular backups are also implemented to safeguard data during this critical stage.
Progress is measured through a series of defined milestones, starting with the creation of a detailed bug log to record and prioritise any issues found during testing. Each issue is systematically tracked through to resolution, ensuring complete transparency and accountability. Once all items have been addressed and verified, we conduct a final staging site sign-off – confirming that the site meets both technical standards and business expectations before moving confidently into launch.
Launch & Post-Launch Support
With testing complete and approval secured, the project moves into the launch and post-launch phase. The goal at this stage is a smooth transition to the new platform with minimal downtime and no disruption to the customer experience. A detailed launch plan guides the process, supported by real-time monitoring tools and dashboards that track site performance, traffic, and key KPIs from the moment the site goes live. Our team remains on hand to quickly identify and resolve any immediate issues, ensuring stability and continuity during the crucial early hours and days of operation.
Once the site is live and performing as expected, attention shifts to ongoing optimisation and support. We provide a tailored support package to help you adapt to the new platform, fine-tune performance, and respond to evolving business needs. This ensures your ecommerce environment continues to perform effectively long after launch, supported by clear data insights and proactive maintenance.

Frequently asked website migration questions
Will I lose my SEO ranking when migrating?
No – if done correctly, SEO losses can be minimized. We manage this via URL redirect mapping, preserving key content, metadata, internal linking, and ensuring continuity for Google (via sitemaps, canonical tags, etc.).
How much data can be migrated (orders, customer history, etc.)?
We typically migrate full customer & order history, product catalogs, reviews, content pages, etc. It depends on the legacy system access and format. Sometimes old data needs cleaning or reformatting.
What about downtime?
We plan migrations to minimise downtime, often using staging environments and launch windows during low traffic periods. With good planning, many migrations have near-zero visible downtime.
Will my custom features / integrations still work?
Yes – we audit all current custom functionality, then plan how to re-implement or integrate them in the new platform, often using apps, APIs, or custom development.
What platforms do you migrate to?
We work with Shopify and our own highly flexible and customisable eCommerce platform. We’ll recommend the best target platform for your business needs, as both are suited for different requirements.
