Ecommerce migration explained

What actually happens when you move platform, in four steps and under two minutes. Full transcript below if you would rather read it.

The four steps: discovery and data mapping, site build and data migration, bespoke integration and URL mapping, then testing and go-live. Your existing store keeps trading throughout — nothing switches over until testing is finished.

The four steps, in a bit more detail

The same shape whether you are coming off Visualsoft, Magento, WooCommerce, OpenCart or something built in-house fifteen years ago.

1

Discovery and data mapping

Before anything moves, we audit what you currently have:

  • Catalogue
  • Custom functionality
  • Integrations
  • SEO footprint
  • Data structure

The migration plan is built around what we find, not a template. Every data type is mapped to its equivalent on the new platform before any migration begins, and anything that does not map directly is handled carefully rather than dropped.

2

Site build and data migration

The new store is built while your existing store stays fully live and trading. No downtime, and no risk to current revenue.

Products, variants, images, customers, orders, CMS content and all associated data are transferred and validated. Nothing left behind.

3

Bespoke integration and URL mapping

Everything hanging off the side of your store gets rebuilt and reconnected:

  • ERP connections
  • Warehouse systems
  • Payment gateways
  • Email automation
  • Analytics

Every URL on the old platform is mapped to its equivalent on the new one, with 301 redirects set up and validated before go-live. A post-migration technical SEO audit is included.

4

Testing and go-live

Checkout, payments, tax calculations, shipping, emails, returns, stock updates and integrations are all tested before anything changes for your customers.

We go live when testing is complete, not when the calendar says so. DNS cutover happens at the planned point, followed by intensive monitoring in the days immediately after launch. Issues are fixed immediately — no disappearing after delivery.

If you want the detail underneath it

The video is deliberately short. These go considerably deeper, including the bits people worry about most: cost, timescales, and what happens to orders placed mid-migration.

What our clients say

19 clients. A few of their words.

Working with Dev Partners to redesign and modernise our WMS system: the whole process has been thoroughly professional from the outset and a delight to work with. Cannot recommend enough.

Great agency. Have used Dev Partners for several years and they have built 20+ sites for us, in addition to taking on our legacy websites, upgrading and maintaining. Easy to work with and some great practical ideas to improve our digital offerings.

Jones Hire have been working with Dev Partners on several projects, which have been very successful. They linked our catering database to a new improved website so clients can easily place and update orders, created a custom warehouse picking app to fulfil all our challenging requirements, and are currently developing a custom transport app to streamline our loading and delivery process.

We have been trying to reinvent our website for over 5 years, trying to make it convert and failing each time. Spoke to Rob at Dev Partners, the team helped create our new site and the improvement was instant.

We have been working with Rob and the team for about 10 years now. Dev Partners helped us build a completely bespoke CRM from scratch which manages our daily business and is always well maintained. We have been able to use the system and roll it out in our new franchise branches.

We collaborated with Dev Partners on the front end of a fairly complex telemarketing platform. Rob and Jason took the time to properly understand the moving parts, asked the right questions, and delivered a clean, intuitive interface that's made the system far easier for our team to use.

I have been working with the team at Dev Partners for the last 3 years and we have always been impressed with the speed in which they act on things for us, along with the honest open communication. The team are a valuable and vital part of our supply chain.

We've had a program for our business in the electronic security sector that Dev Partners developed and keep up to date. They've never let us down, always there when needed. Thanks Rob and the team.

Dev Partners have been working with us for just over 2 years. They have significantly upgraded and redesigned our existing web platforms, and always deliver a first class service.

Dev Partners helped us build an event website. The team were very knowledgeable, easy to work with and quick to deliver a high quality product.

Working with Dev Partners has been an exceptional experience. Their team is highly skilled, professional, and committed to delivering results. What truly sets them apart is their communication and transparency; we always felt informed, supported, and confident.

We've worked with Dev Partners a few times to support us on bespoke web build tasks. They're very easy to work with, approachable, and explain the detail in a way that's understandable. A great partner for technical issues at sensible prices.

Excellent customer service backed up with solid experience. As a media business we have had five websites built by Dev Partners. I would certainly recommend them.

Found Dev Partners and they were great, nothing too much trouble. They managed to help us with integrating our old existing system with Shopify.

I've worked with Rob and his team off and on for many years and have always found them to be professional, knowledgeable, and best of all, they listen to their clients and deliver what is required.

We have worked with Dev Partners for 7 years and can highly recommend them for their expertise and excellent customer service.
