Contentful CMS migration: the fastest route to a website relaunch
Most website relaunches don't run late because of the design or the build. They run late because of the content.
Why website relaunches always take longer than expected
The content migration problem nobody talks about
Ask a digital leader what makes website projects run late and you'll hear: scope creep, stakeholder sign-off delays, technical integrations. What you won't often hear, but should, is content migration.
Content migration is the stage that gets the least attention in project planning and causes the most delays in execution. It's estimated in hours, executed in months. The reason is straightforward: the volume is always higher than expected, the quality of existing content is always lower than assumed, and the people tasked with doing it always have day jobs.
For organisations with large content sets, hundreds of service pages, years of blog archives, thousands of assets and documents, manual migration is a project within a project. And it sits squarely on the critical path.
What manual migration actually looks like in practice
Scenario A: The manual migration nightmare
A mid-sized Wellington professional services firm kicks off a website relaunch. The build goes well. The design is approved inside six weeks. Then the team hits content: 400 service pages, six years of blog posts, and 3,000 PDF downloads that need to be catalogued and linked.
The internal marketing team is tasked with migrating the content into the new Contentful environment. Three months later, 60% of the content is across. Forty percent has formatting errors. The development team can't complete testing because the content isn't complete enough to validate layouts at scale. The launch date has slipped twice. The project is six months in and still three months from going live.
This is not an unusual story. It's a predictable outcome of treating content migration as a task rather than a discipline. The problem isn't effort, the internal team is working hard. The problem is method.
What programmatic content migration to Contentful actually means
Extract, Transform, Load: the three steps
Programmatic migration uses an Extract, Transform, Load (ETL) approach. It's an automated process, not a manual one. Here's what each stage involves:
Extract: Content is pulled from the source system, WordPress, Drupal, HubSpot CMS, Magento, or a custom CMS, using its database or API. All content types, metadata, asset references, and URL structures are captured in the extraction, not just the visible text.
Transform: Extracted content is mapped to the Contentful content model. This is where structure is applied, matching source fields to destination fields, reformatting rich text for Contentful's format, and handling edge cases like embedded media, custom shortcodes, or legacy HTML.
Load: Transformed content is pushed into Contentful via the Content Management API (CMA). Entries are created at scale, assets are uploaded, and references between content types are preserved.
Repeatable scripts handle the heavy lifting. What would take an internal team months to do manually can run overnight.
Which source platforms Contentful CMS migration covers
The sources most commonly migrated to Contentful include:
WordPress, the most frequent source platform, whether using the native WordPress database or a headless WordPress setup
Drupal, common in government and enterprise, often with complex content models and large document libraries
HubSpot CMS, increasingly common as organisations move from marketing-site tools to structured content platforms
Magento, typically for product catalogue migration alongside broader digital platform builds
Custom CMS and CRM platforms, legacy systems with proprietary data structures, handled through bespoke extraction tooling
Contentful-to-Contentful migrations are also supported, useful for organisations restructuring their content model, merging Contentful spaces, or moving between environments.
What gets preserved
One concern that comes up regularly is SEO, specifically, whether migration will wipe out years of accumulated ranking signals. A well-executed programmatic migration preserves:
URL structures and redirects, existing URLs are mapped and 301 redirects are configured as part of the migration
Metadata, page titles, meta descriptions, Open Graph data, and structured data are extracted and carried across
SEO signals, canonical tags, hreflang settings, and internal link structures are preserved
Document libraries, PDF assets are migrated and relinked, not lost
Post-migration, accuracy validation confirms the content has transferred correctly before anything goes live. Learn more about how Contentful handles day-to-day content editing after migration if you're planning the full operational model.
Contentful CMS migration timeline: manual vs. programmatic
How long does it take to migrate content to Contentful? With manual migration: three to six months for a site of 300–800 pages. With a programmatic Contentful CMS migration: typically five to ten days for the same volume. The table below shows what that difference means for your overall relaunch schedule.
The business case is not subtle. Here's what it looks like in concrete terms:
| Approach | Typical timeline |
| Traditional relaunch (manual migration) | 6–12 months |
| Launch Pack only (greenfield or small content set) | 4–6 weeks |
| Launch Pack + programmatic migration (large content set) | 6–10 weeks |
| Traditional relaunch with programmatic migration | 3–5 months |
The 80% time reduction figure from Apolinar's content and data migration service isn't an aspirational claim, it reflects what happens when you take a process that normally runs across months of manual effort and compress it into a matter of days. An organisation that would otherwise spend four months on content migration runs that same migration in a week.
Scenario B: The programmatic contrast
The same firm. The same content set: 400 service pages, a six-year blog archive, 3,000 documents. But this time, Apolinar runs a programmatic migration. The existing WordPress installation is audited, a content model is mapped to Contentful's structure, and extraction scripts run overnight. Within a week, all content is in the new Contentful environment, correctly structured, with metadata intact and redirects mapped. The development team has a complete content set to test against from day one. The launch proceeds on the original six-week timeline.
The difference isn't working harder. It's removing a process that was never designed to scale.
How programmatic migration unlocks a faster build
Content migration on the critical path vs. in parallel
In a traditional relaunch, the sequence looks like this: design, build, then migrate content, then test, then launch. Content migration sits at the end of the process, and any delay there delays everything that follows.
Programmatic migration changes that sequencing. Because content can be extracted and structured early, it can run in parallel with design and build. The development team has real content to work with from week one. Layouts are tested against actual page lengths. Edge cases surface before launch, not after.
This isn't a marginal efficiency gain. It's a structural change to how a relaunch project runs.
Having complete content from week one
There's a subtle but significant benefit that's often underestimated: working with complete content during the build phase produces a better-built site. When developers are building against placeholder content, they're making assumptions. When they're building against real content, they're solving real problems.
Image ratios, text truncation, content-heavy vs. content-light layout variants, multi-language considerations, all of these become visible earlier when actual content is present. The QA phase is shorter because the surprises are fewer.
Post-migration validation
Before anything goes live, programmatic migration includes an accuracy validation pass. This checks that entry counts match, that rich text has rendered correctly, that asset references resolve, and that metadata is present where expected. Any discrepancies are caught and corrected before launch rather than after.
Combining migration with a Website Launch Pack
What a Launch Pack delivers in 4–6 weeks
A Website Launch Pack is a fixed-scope, fixed-cost Contentful implementation that covers the full launch stack: information architecture, content modelling, design system, CMS configuration, integrations (HubSpot, Salesforce, Zoho), accessibility, SEO, performance, and staff training.
The timeline is 4–6 weeks. Subsequent multi-site implementations using the same foundation are faster still. Predictability is a core feature, organisations with a campaign launch, financial year deadline, or board-mandated timeline know exactly when they'll go live.
How migration runs in parallel with design and build
The integration of programmatic migration into a Launch Pack engagement works like this. While content is being modelled for Contentful (a week-one activity in a Launch Pack), the extraction phase begins in parallel. By the time the content model is finalised, the first extraction is already running against it.
The build phase, which runs through weeks two to four, has real content to work with. The testing and sign-off phase in weeks five and six runs against a complete, production-ready content set. There is no migration tail; the content is there from the start.
The combined timeline in practice
Scenario C: The combined result
A Wellington-based financial services company needs a full website relaunch: new brand, new Contentful CMS, HubSpot integration, and 800 pages of content to migrate from a legacy Drupal installation. The old way would have taken eight to ten months minimum, the Drupal migration alone would have run to three or four months of manual effort. With a Website Launch Pack and programmatic migration running in parallel: eight weeks from kickoff to go live. The migration ran in the background during weeks one to three while the build took shape. By week four, the team was testing against real, complete content.
That is not an unusual outcome. It is what the combined approach is designed to produce. GS1 Australia moved to two-week release cycles on the back of a similar engagement, replacing what had been months-long feature deployment cycles with rapid, iterative delivery.
Which businesses benefit most from programmatic migration
Programmatic Contentful migration delivers the clearest gains for organisations that meet one or more of these criteria:
Large content sets: 200+ pages on a legacy CMS (WordPress, Drupal, Magento, or a custom platform). Below this threshold, a manual migration may be manageable; above it, programmatic is almost always faster and more accurate.
Prior relaunch experience: Organisations that have been through a slow relaunch before and understand the cost of running six months late — in delayed SEO recovery, deferred campaign launches, and extended project burn rates.
Hard deadlines: Businesses with a campaign go-live, financial year milestone, or product launch that makes the relaunch timeline non-negotiable. A programmatic migration can be scoped and scheduled; a manual one cannot.
Multiple sites: Organisations managing multi-brand or multi-market environments where content exists across several platforms and needs to be consolidated into a single Contentful space.
Content migration services in NZ and Australia are increasingly sought by organisations that have been burned by a slow relaunch and want a predictable, proven alternative. If any of these criteria sound familiar, content migration is likely your critical path item — and the fastest way to shorten it is to remove the manual process entirely.

Getting started with Contentful CMS migration
The starting point for any Contentful CMS migration engagement is a content audit: what exists, where it lives, what needs to come across, and what can be left behind. This shapes the content model and determines the extraction approach. It also surfaces the content that needs reformatting or reauthoring during migration, a decision that's much easier to make before scripts run than after.
From there, the process is structured:
Audit the source platform(s) and map content types
Design the Contentful content model in parallel with the extraction phase
Run extraction and transformation against the content model
Validate accuracy before the build is complete
Load final content and configure redirects ahead of go-live
When this runs as part of a Launch Pack engagement, steps one to four complete in the first three weeks. The build is done on real content. The launch is on time.
If you're planning a website relaunch and content volume is a concern, the combination of our content and data migration service and a Website Launch Pack is the fastest route from here to live. Both services are available as a combined engagement or separately, depending on where you are in your planning.

The reframe worth making
Website relaunches feel like design and technology projects. In practice, they're content projects that happen to involve design and technology.
Until you treat the content as the primary constraint, and address it with tools designed for the scale, you will keep getting late launches. Programmatic Contentful CMS migration removes the bottleneck. A Website Launch Pack provides the structure around it. Together, they turn a six-to-twelve-month project into one that's done in six to ten weeks.
The question is not whether that's possible. It is. The question is whether you want to go that way.
