Shopify migration agency

Replatform to Shopify without losing what already works

A migration is not a theme project. It is a controlled change across customer data, product information, URLs, integrations, operations and the team running the store. We plan the whole cutover before anything business-critical moves.

Protect revenue, data and organic visibility while building a better operating model.

Migration scope before build

We define which products, customers, orders, content, URLs and integrations move, and what should be retired instead of carried forward.

SEO is part of the cutover

Redirect mapping, crawl controls, metadata and monitoring are migration workstreams, not a checklist added the night before launch.

Parallel build, controlled switch

The new store is built and tested alongside the current platform. Cutover steps, ownership and rollback decisions are documented in advance.

Operational readiness matters

Payments, fulfilment, customer service, finance and reporting need to work on day one. Training and acceptance criteria are planned with the build.

Our approach

A migration plan with no hidden workstreams

Audit and
inventory

Platforms, data, URLs, integrations and business-critical workflows.

Target
architecture

Shopify plan, market model, data ownership and solution boundaries.

Data and
URL mapping

Transformation rules, test migrations and redirect coverage.

Build and
integration

Storefront, extensions and connected systems implemented in parallel.

Acceptance
and SEO QA

Functional, content, analytics and crawl checks against agreed criteria.

Cutover and
monitoring

Sequenced launch, owner checklist and post-launch issue triage.

Scope and deliverables

Migration work is estimated from evidence, not page counts alone. We identify data quality issues and third-party constraints early enough to make decisions.

Who it is for

Built around the way your business actually works

For commerce teams moving away from technical debt, high operating costs or a platform that no longer supports the roadmap.

01 · Replatforming

Magento to Shopify

Reduce platform overhead while preserving essential B2B, international and integration capabilities.

02 · Replatforming

WooCommerce to Shopify

Move from a plugin-heavy environment to a clearer commerce operating model.

03 · Consolidation

Multiple stores or markets

Replace fragmented stores with an architecture that is easier to govern and localise.

04 · Data

Complex catalogue and customer data

Map source data deliberately instead of importing legacy structures without a business reason.

Commercial value

What a strong implementation changes

A good migration reduces future complexity instead of reproducing it on a new platform.

Lower operational friction

Fewer manual steps and clearer ownership make the platform easier to run day to day.

Preserved search equity

A complete redirect and SEO plan reduces avoidable loss, while acknowledging that no agency can guarantee unchanged rankings.

Cleaner architecture

Legacy customisations are challenged against real business needs before they become new technical debt.

A safer launch

Test migrations, acceptance criteria and a cutover runbook turn launch into a managed event.

Client voices

Trust is built by what happens after launch.

Working with Growly has been exceptionally smooth from the start. The team is agile, responds quickly and is available when help is needed. What we value most is that Growly does not view every question purely through code. They understand the commercial side of ecommerce and propose solutions that genuinely support sales and growth. Their technical expertise spans Shopify development, SEO and the wider commerce stack. Work that had taken our previous partner months was resolved by Santeri within hours after a few WhatsApp messages. I warmly recommend Growly. They approach our business with genuine commitment and strong professional expertise.

Annika Klemetti, E-Commerce Team ManagerHappy Angler

We needed a dependable partner with a deep understanding of Shopify and a genuine interest in the client’s business and specific requirements. Growly has met that need extremely well. The collaboration has been straightforward, effective and results-focused from the outset. The project stayed on plan and costs remained under control. I would gladly recommend Growly to any company planning a Shopify implementation.

Tuomas Aitolehti, CEOMurren Murkina Oy

We gave three Shopify agencies access and asked each for an assessment. Growly was by far the fastest to respond. We commissioned a new SEO-optimised store and the entire project was completed in five weeks. Organic visibility is developing very well. A strong recommendation.

Frequently asked questions

Questions, answered

Yes. We plan the move around the source platform, data quality, integrations, SEO footprint and required Shopify capabilities. The migration method and scope differ by platform and business model.

A migration can be designed to reduce avoidable SEO loss through URL mapping, redirects, equivalent content, crawl controls and monitoring. No responsible agency can guarantee completely unchanged rankings because search engines recrawl and reassess the new site.

Typical scope includes products, variants, collections, customers and an agreed level of order history. Feasibility depends on source access, data quality, consent requirements, Shopify’s data model and the purpose of carrying each dataset forward.

Normally yes. The Shopify store is built and tested in parallel. A controlled cutover moves the domain and active integrations once acceptance criteria are met.

A focused migration can fit an 8 to 12 week delivery window. Multi-market, B2B and integration-heavy migrations often take several months. We confirm the schedule after auditing the current environment.

Yes. We can cover launch monitoring, issue resolution, backlog delivery, performance work and ongoing optimisation under an agreed development model.
