Legacy Modernisation for eCommerce — UK Specifics
Strangler Fig for Legacy eCommerce Platforms
UK eCommerce legacy modernisation typically involves replacing Magento 1 (EOL October 2022 — no security patches), legacy WooCommerce with years of customisation, or bespoke PHP platforms from 2008–2015. Strangler Fig pattern: build new Next.js/headless commerce frontend connecting to the legacy backend via API, progressively migrate product catalogue and checkout to new system, decommission legacy when migration complete.
Magento 1 Migration to Modern Headless Stack
Magento 1 end-of-life (October 2022) left many UK eCommerce businesses with unsupported, unpatched software — a PCI-DSS and UK GDPR Article 32 security obligation failure. Migration path: export product catalogue to structured data, migrate to headless architecture (Next.js frontend + Shopify/BigCommerce/custom backend), migrate customer accounts (with UK GDPR compliant data migration), and redirect all URLs (SEO preservation critical for established retailers).
Customer Data Migration with UK GDPR Compliance
Migrating customer data from legacy eCommerce platforms requires a UK GDPR-compliant data migration plan: DPIA for the migration process (temporary processing in migration environment), data minimisation (migrate only data still within retention period), legacy customer password hashes (must be rehashed in new system — legacy bcrypt migration), and consent records migration (marketing consent from legacy must be preserved and verified before marketing restart in new platform).
UK Consumer Rights Act in New Platform Architecture
Legacy eCommerce migration is the opportunity to build UK Consumer Rights Act compliance in correctly: 14-day cancellation right (digital tracking of cancellation window), digital goods delivery guarantee (downloadable products available immediately), returns tracking with Consumer Rights Act reason codes, and complaint journey testing.

Frequently Asked Questions
Common questions about ecommerce software development.
How long does eCommerce legacy modernisation take?
eCommerce legacy modernisation typically takes 12–26 weeks depending on: platform complexity, number of third-party integrations (payment gateways, carriers, ERP), catalogue size (100 products vs 100,000 products), and custom functionality. ClickMasters uses a discovery phase (£3,500–£8,000) to scope accurately before committing to a fixed price.
How do we migrate customer data without UK GDPR violations?
Data migration DPIA required. Staging environment data minimisation: use production-like anonymised data for testing where possible. Customer password hashes: legacy bcrypt/MD5 hashes must be re-hashed on first login in new system (not migrated directly). Consent records: map legacy consent database to new consent management system with full audit trail. Customers who have not consented to marketing cannot be added to new marketing lists.
