Why Teams Migrate Their CMS
Teams migrate when the current CMS costs them rankings, developer time or growth.
SEO AT RISK ON EVERY RELEASE
Outdated or plugin-heavy setups break structure, metadata and speed, and each update can cost rankings that took years to earn.
EVERY CHANGE NEEDS A DEVELOPER
Rigid content models and workarounds turn a copy change into a ticket, so marketing waits and maintenance costs grow.
THE PLATFORM SLOWS GROWTH
New sections, markets and language versions wait on developers, so the content plan slips as the site grows.

Choose Your CMS Migration Path
Find your platform below to see how Pagepro moves it to Next.js and Sanity without losing rankings.
YOUR CURRENT PLATFORM | HOW PAGEPRO MOVES IT |
WordPress: plugin-heavy sites and large blogs | Pagepro moves posts, media and URLs 1:1, so old links keep working |
Contentful: rising plan costs and less control over content | Pagepro maps Contentful models and references to Sanity schemas, structure intact |
Drupal: complex content types on an ageing release | Pagepro moved Learn Squared's e-learning platform from Drupal to Next.js |
Webflow: a CMS your content has outgrown | Pagepro moves Webflow collections to Sanity and keeps redirects and metadata |
Legacy or custom CMS: slow to change, hard to maintain | Custom CMS SEO migration: Pagepro moved GPnotebook's 100,000+ pages to Next.js and Sanity |

HOW WE MIGRATE YOUR WEBSITE
A Pagepro website migration moves content, architecture, SEO equity and editorial workflows to Next.js and Sanity in one fixed-price engagement.
WEEK 1: WE AUDIT YOUR CURRENT STACK FOR MIGRATION RISKS
Before we write a line of code
Legacy sites fail during migration in predictable ways. We analyse your codebase and current site before scoping anything.
Full URL crawl: every page inventoried, SEO equity mapped
Content types and CMS structure analysed for Sanity migration
Core Web Vitals benchmarked
You get a fixed scope and price before any commitment
WEEK 2: YOUR CONTENT MOVES WITH YOU, NOT ONLY YOUR CODE
Content first, always
Every piece of content, every media asset, every redirect. Moved to Sanity with a schema designed for your editorial team's actual workflows.
Full content + media migration to Sanity
301 redirect map generated from old URL structure
Redirect management built into Sanity Studio, no dev needed
Editorial schema designed for your team's publishing patterns
WEEK 3: YOU PAY FOR YOUR SITE, NOT FOR SETUP
Weeks of setup already done
Every new Pagepro migration runs on Nexity, Pagepro's Next.js and Sanity starter. Routing, SEO, content blocks and the CMS schema already exist, so the budget goes to your content and your pages.
Next.js App Router + TypeScript strict + TurboRepo monorepo
30+ pre-built content blocks, no reinventing the wheel
SEO out of the box: metadata, OG, sitemap, structured data
Performance targets: Lighthouse Mobile 90+ at launch, Core Web Vitals (LCP, INP, CLS) in the good range for real users
Week 4: We prepare the website for real users
Production-ready, not staging-ready
The final week is for validation. The site goes live only when it passes the agreed acceptance criteria.
QA against all pre-agreed acceptance criteria
Lighthouse score checked before launch
Redirect testing: every old URL checked
Editor training delivered, so your team owns the CMS from day one
Architecture documentation handed over
Production-Ready Foundation in 4 Weeks
If your site fits the standard 4-week Nexity engagement, Pagepro hands over a production-ready foundation: content migrated, core journeys working and editors trained.
If the audit shows a longer engagement is needed, we tell you upfront. Fixed scope. Fixed price. Agreed before any code is written.
No vague timelines. No open-ended retainers.
Custom integrations and advanced features are scoped and estimated as a separate phase after handover.

"Generic agencies migrate any site to any platform. We only migrate to NEXT.JS + SANITY.
That's not our limitation. It's why we're 30% faster, why we have zero SEO drops, and why clients come back.

We've absolutely seen an increase in development velocity with the Pagepro team, through initial development and even into the initial weeks of our first SLA. I don't really have a number of hours to represent that increase, but as the one who oversees operations of development, I can confirm the turnaround time from ideation to feature launch has been a marked improvement upon our previous development solution.
Pagepro was excellent from a project management perspective, thanks to their budget flexibility and timely adherence to our deadlines.
As a Nextjs Development Company Pagepro exhibited strong execution. They understood our technical goals and our desired performance metric. They were also very detail-oriented, and helped us achieve the KPIs we set for the project, including a lighter website, increased speed, and better SEO ranking.
CMS and Website Migration FAQ
Will my SEO rankings drop during a website migration?
Not if the migration is planned around your URLs. Pagepro has no recorded SEO ranking drop across 20+ migrations. Every Pagepro migration starts with a URL inventory from several sources, then a 301 redirect map and redirect checks before go-live. Redirects are managed in Sanity Studio, so editors add a 301 without a developer.
How much does a website migration service cost?
Pagepro sets a fixed price after a free migration assessment, before any code is written. The price depends on the number of pages and content types, the integrations, and how much data moves. For typical ranges and what drives them, read our website migration cost guide.
How long does a website migration take?
A standard Pagepro migration on Nexity delivers a production-ready foundation in 4 weeks. Week 1: an audit of your current site, a 48h live demo with your content, fixed scope confirmed. Week 2: content migration to Sanity and redirect mapping. Week 3: core pages built on Nexity, staging live. Week 4: QA, Lighthouse verification, editor training, handover.
Which Platforms Can Pagepro Migrate From?
Pagepro migrates from WordPress, Drupal, Contentful, Webflow, custom PHP and other legacy CMS platforms. Today Pagepro migrates to one stack only: Sanity as the CMS and Next.js on Vercel as the frontend, because a migration to one stack Pagepro knows well is faster and safer. The code repository stays yours. For a new build without a migration, see headless CMS development.
What Does CMS Migration SEO Include at Pagepro?
Pagepro's CMS migration SEO covers the full URL inventory, a 301 redirect map, metadata and structured data carried over, internal link updates and canonical tags, and a cutover-day checklist run on production before the old site is switched off. The same scope applies to an SEO migration for a custom CMS.
Migration Risks: Common Questions
Our Traffic Dropped After a CMS Migration. Can Pagepro Help?
Yes. Pagepro compares the new site with the old one: which URLs lost traffic, where redirects are missing or chained, and which pages lost metadata or content. The fixes follow the rules of Pagepro's own migrations: direct 301s, no redirect chains and no mass redirects to the homepage. For a Next.js site, the Next.js SEO and AI optimization audit takes one week.
How Does Pagepro Handle Redirects for Thousands of URLs?
Pagepro builds the URL list from several sources, not from one sitemap: the old sitemap, a full crawl, Search Console, analytics, backlink data and, where possible, server logs. For Finvisor's WordPress to Next.js and Sanity migration, the launch inventory had 950 URLs from 8 sources. Every URL gets a target before launch, and the redirect map is checked against the inventory before and after go-live.
What Happens If Something Goes Wrong at Launch?
Pagepro runs a cutover-day checklist: noindex settings and robots.txt, the sitemap, the https and www redirects, and a URL re-run on production. Deploys run through your own pipeline, usually Vercel, with one-click rollback. On Finvisor, Pagepro set up separate staging and production in Sanity, so the team kept a safe place to test after launch.
Can Pagepro Take Over a Migration Another Supplier Started?
Yes. Pagepro starts with an audit of the code and the work done so far, with access to the real repository, not a code export. You get a list of what works, what is missing and what is at risk, then a fixed scope for the rest. If the migration targets Next.js and Sanity, Nexity speeds up the remaining work.
Do We Own the Code After the Migration?
Yes. The code repository is yours, and Pagepro transfers it when the project ends. Your team or another supplier can keep working on the code. Pagepro can stay on under Continuous Development & Support, the SLA, but you are never locked in.
Migration Planning: Questions From CTOs
How Does Pagepro Move Rich Text Into Sanity?
Rich text moves into Sanity's Portable Text, which stores formatting as structured data instead of HTML. Pagepro agrees with your team which formatting each part of the site keeps. On Finvisor, page sections allow headings, bold text and highlights only, and blog posts keep full rich text, so editors cannot break the layout of key pages.
Can Pagepro Migrate a Multi-Language Site?
Yes. Pagepro uses document-level internationalization in Sanity: each language version of a page is its own document, linked to the other versions, so editors translate a whole page at a time. Pagepro sets up the language routes in Next.js before go-live, not after.
What About Forms and Other Integrations?
Nexity includes form and FAQ blocks, so standard forms move inside the 4-week foundation. Custom integrations, for example a DAM such as Bynder, are scoped and estimated as a separate phase after handover.
What Does Our Team Need to Do During the Migration?
Three things. In week 1, give Pagepro access to the current site and confirm the scope, so the 48h demo uses your real content. Before launch, review the content inside Sanity, not only on the front end, and plan time for this review. In week 4, your editors take the training, so they own the CMS from day one.
How Does Pagepro Handle Security and Compliance?
Pagepro does not host your systems. Your data stays on platforms you control, such as your GitHub, Sanity and Vercel accounts. Pagepro is an EU company, so GDPR applies by default, and every team member signs confidentiality and IP-assignment agreements before getting access. When the contract ends, Pagepro deletes its local copies and revokes all access within 30 days, and confirms the deletion in writing on request.
