Healthcare CMS Replatforming: WordPress to HubSpot CMS Migration with BigCommerce Integration
A medical device manufacturer had high bounce rates whenever users moved from informational pages to a sluggish BigCommerce storefront. We replatformed the marketing site to HubSpot CMS. We used HubDB to render products dynamically and mirrored global design tokens to close the visual and performance gap across subdomains.
Executive Summary
Context
A provider of portable oxygen concentrators had to leave a legacy WordPress environment. It was slowing down marketing response times.
We replatformed the marketing frontend to HubSpot and optimized a BigCommerce instance for high-value medical device transactions.
What We Built
We built a unified CMS architecture. HubSpot handled lead-gen. HubDB handled product management. A post-migration performance audit of the BigCommerce transactional layer backed it up.
Tech Stack
- HubSpot CMS: Marketing site and lead-gen host
- BigCommerce: Transactional engine (shop. subdomain)
- HubDB: Product data management and dynamic rendering
- Google Tag Manager: Cross-platform tracking layer
- WordPress: Legacy source system.
Not a fit for a simple design lift with no underlying system changes. Also not a fit without a separate eCommerce subdomain.
The Challenge
The legacy WordPress environment had become an operational bottleneck. It slowed down the deployment of new Rent-To-Own programs and medical device updates. The worst friction sat on the BigCommerce subdomain, where page load times exceeded 2.7 seconds. That created a jarring platform jump for users moving from informational content to the checkout flow. The migration had to preserve SEO equity while closing the performance gap between the marketing site and the shop.
Our Approach
We treated the migration as a performance optimization project. It was not a content move. We established a shared design system between HubSpot and BigCommerce to eliminate visual friction. To solve the data management hurdle, we mapped the product catalog to HubDB. That let the marketing team update specifications in one place, and those updates rendered dynamically across the HubSpot site. After launch, we ran a technical audit that found specific asset compression and caching failures on the BigCommerce side, which led to a targeted fix for the shop's load speed.
Impact
Zero-Data-Loss Migration in a 6-Week MVP
We moved all brand assets and landing pages from WordPress to HubSpot CMS. The 6-week MVP timeline held, with no data loss.
Unified UI/UX Architecture
We mirrored global headers and design tokens across HubSpot and the BigCommerce shop subdomain. That eliminated the platform-jump friction.
Remediated Subdomain Lag
We found post-launch load issues on BigCommerce and fixed them. That brought the equipment shop in line with the high-performance HubSpot frontend.
Decoupled Content Management
We shifted product management to HubDB. Now the client updates device configurations and pricing without manual code edits or developer tickets.
Instead of hard-coded specs for the Vitality and Explorer device lines, we used HubDB to render comparison tables dynamically. That kept data consistency at 100% across educational pages.
We implemented one Google Tag Manager container. It spans the primary domain and subdomains. That kept the user's session ID intact across the jump from CMS to eCommerce.
We mapped a full 301 redirect strategy for legacy WordPress URLs. High-intent pages came first. That order kept organic search ranking intact during the replatforming.
We used Lighthouse and site speed analytics to flag unoptimized assets on the legacy BigCommerce theme. That triggered a fix. A compression and script-deferral plan stabilized cross-site load speeds.
A hybrid CMS architecture replatforming a legacy WordPress site to HubSpot and BigCommerce. It centralizes hardware specifications in a HubDB engine for dynamic rendering while managing transactions on decoupled subdomains. A targeted caching optimization layer resolves load time bottlenecks, maintaining unified marketing attribution via a GTM bridge.
FAQ
The primary risk is broken link equity. We crawl the legacy WordPress site to find every indexed URL and map it to a new HubSpot equivalent in a detailed redirect file. That tells search engines exactly where the content moved, and it preserves the ranking power of your historical pages.
