What are the steps in a replatforming project?
Phase 1 · Week 1
How is the current site audited before migration?
Every indexed URL is exported from Google Search Console, the existing sitemap and a full crawl, then ranked by traffic and revenue. Templates, integrations, forms and tracking are inventoried so nothing silently disappears at cutover.
Deliverable: URL inventory, template map, integration list.
Phase 2 · Week 1
How is the new platform chosen?
The platform is chosen against the actual requirements: editing workflow, product count, checkout control, integrations, budget and team skill. Defaltam recommends the smallest platform that meets them rather than the largest one available.
Deliverable: Written platform recommendation with costs.
Phase 3 · Week 2–3
How is content and data migrated?
Pages, posts, media, products, categories, customers and orders are exported and imported with field-level mapping. Titles, meta descriptions, canonical tags, hreflang and schema.org markup are carried across unchanged.
Deliverable: Populated staging site with all content.
Phase 4 · Week 3
How are redirects handled?
Every old URL gets a 301 redirect to its closest match on the new platform — one hop, no chains, no redirects to the homepage. The map is reviewed line by line and tested automatically before cutover.
Deliverable: Tested 301 redirect map, delivered as a spreadsheet.
Phase 5 · Week 3–4
How is the site tested before launch?
Staging QA covers Core Web Vitals (LCP under 2.5s, INP under 200ms, CLS under 0.1), mobile layout, forms, payments, tracking events and every redirect. Nothing goes live until the checklist is clear.
Deliverable: Signed-off QA checklist and performance report.
Phase 6 · Cutover day
How does cutover work?
DNS is switched in a low-traffic window with redirects already active. The new sitemap is submitted to Search Console the same hour and indexing is watched live.
Deliverable: Live site on the production domain, zero downtime.
Phase 7 · Days 1–30 after cutover
What happens after the migration?
Rankings, impressions, crawl errors and conversions are monitored daily for 30 days. Any 404, redirect gap or ranking drop is fixed at no extra cost within that window.
Deliverable: 30-day post-migration report and fixes.
When should a business replatform?
- — Pages load slower than 3 seconds and no plugin or caching layer fixes it.
- — Content edits require a developer instead of a marketer.
- — Plugin, theme and licence renewals cost more than a rebuild would.
- — The platform is out of support and security patches are no longer shipped.
- — The checkout or booking flow cannot be customised for how you actually sell.
- — A previous migration lost traffic and the redirects were never fixed.
Replatforming FAQ
Questions people ask before replatforming.
What is web replatforming?
Web replatforming is moving an existing website or online store from one platform or technology stack to another — for example WordPress to a headless build, Shopify to Shopify Plus, Wix to a custom site, or Magento to a modern stack — while keeping the same URLs, content and search rankings. It is a migration of the underlying platform, not a redesign, although a redesign is often done at the same time.
How long does a website replatforming project take?
Defaltam replatforming projects take 2 to 4 weeks for a marketing site of up to 40 pages and 4 to 8 weeks for an e-commerce store with product catalogue and checkout. The timeline covers audit and URL inventory, rebuild, redirect mapping, staging QA, cutover and 30 days of post-launch monitoring.
How much does replatforming a website cost?
Defaltam prices replatforming as a fixed quote from 2,500 EUR for a marketing site up to 40 pages, from 6,000 EUR for an e-commerce store, and from 9,000 EUR for a catalogue over 1,000 products or multi-language sites. The price is fixed in writing before work begins and payment is 50% upfront, 50% on cutover.
Will replatforming hurt my SEO rankings?
Not when redirects are mapped correctly. Defaltam inventories every indexed URL from Search Console, server logs and the existing sitemap, maps each one to a 301 redirect on the new platform, preserves titles, meta descriptions and structured data, and monitors impressions and rankings daily for 30 days after cutover. Traffic loss usually comes from missing redirects, not from the platform change itself.
Which platforms do you migrate from and to?
Common migrations are WordPress to a modern hand-coded stack, Wix or Squarespace to a custom site, Shopify to Shopify Plus or headless, WooCommerce to Shopify, Magento to a modern stack, and legacy custom PHP to React. Content, media, products, customers and orders are exported and remapped as part of the project.
Is there downtime during the migration?
No. The new platform is built and tested on a staging domain, redirects are loaded before go-live, and DNS is switched during a low-traffic window. The old site stays available until the new one answers on the production domain, so visitors never see an error page.
What signs mean it is time to replatform?
Page load over 3 seconds that plugins cannot fix, a platform that blocks features you need, rising licence or plugin costs, security patches you cannot apply, a checkout you cannot customise, or a CMS your team refuses to use. If content edits require a developer, the platform is the bottleneck.
What do I receive at the end of a replatforming project?
A live site on the new platform, the full redirect map as a spreadsheet, migrated content and data, updated sitemap.xml and robots.txt, structured data, Search Console and analytics reconnected, a 30-day ranking report, and full ownership of the code, hosting and domain.
