The decision to migrate from WordPress to Webflow is usually made for good reasons. WordPress maintenance overhead, plugin conflicts, a developer dependency for tasks the marketing team should be able to handle themselves, a performance ceiling that requires disproportionate technical effort to push past. Webflow addresses most of these concerns legitimately. The migration itself, however, creates a set of problems that are entirely separate from the problems it is solving. Most businesses discover them after launch.
The cost is not in the technical work. The cost is in everything the brief did not account for.
URL mapping is not a migration afterthought
Every page on a WordPress site has an existing URL. Some of those URLs have been live for years, have accumulated inbound links and sit in positions in Google's index that took sustained effort to build. When a Webflow migration changes those URLs without mapping the old ones to the new ones, Google treats the old pages as gone. The rankings attached to those URLs begin to deteriorate within weeks.
This is not a theoretical risk. It happens consistently on migrations where URL structure is treated as a post-launch item rather than a pre-migration architectural decision. The new Webflow site launches, looks better, performs faster, and watches its organic traffic drop by 20 to 40 percent in the following three months because pages that ranked well are now 404 errors or unmapped redirects.
The correct approach is to export the sitemap of the old WordPress site before any work begins, map every existing URL to its new equivalent in Webflow, implement 301 redirects for every change, and verify in Search Console that the redirects are being followed correctly after launch. This takes time and requires someone with genuine technical SEO understanding. It is also not optional for any business that relies on organic search traffic.
The deeper issue is that Webflow's URL structure can be meaningfully different from WordPress. Webflow CMS collection slugs, folder structures and clean URL conventions may not align with the URL patterns that exist in the WordPress install. Resolving those conflicts requires decisions about content structure that affect the migration scope. Making those decisions late in the project means making them under pressure, which is how important redirects get missed.
The content decisions migration forces
A WordPress to Webflow migration creates a moment of forced reckoning with content that most businesses would rather defer indefinitely. Every page needs to move. Every piece of content needs to be assessed. The question that a migration makes unavoidable is one that was easy to ignore when the site was just sitting there: does this content actually belong on the site?
Most WordPress sites accumulate content over years without a systematic approach to retirement. Blog posts that addressed a time-sensitive topic in 2019 are still live because nobody ever got around to removing them. Service pages for offerings the business no longer provides are indexed and occasionally linked from other pages. Category pages with thin content exist because the CMS structure encouraged their creation.
A migration that carries all of this content into Webflow does not solve the content problem. It just moves it to a faster platform with cleaner design. The content issues that were hurting SEO performance on WordPress will continue to hurt it on Webflow.
The migration moment is the correct time to conduct a content audit: identify pages with meaningful traffic or ranking positions and prioritise their careful migration, identify thin or outdated content and either consolidate or retire it, and establish the Webflow CMS collection structure around the content that should exist rather than the content that currently exists. This adds scope to the project. It also removes a significant drag on post-migration performance.
CMS architecture shapes everything downstream
Webflow's CMS is structured around collections: defined content types with consistent fields and templates. Building those collections correctly requires decisions about how content is organised, what fields each content type needs, and how collection items relate to each other. These decisions have long-term consequences for how the marketing team can update and expand the site.
A collection architecture designed to match the old WordPress structure will produce a Webflow CMS that is technically functional and practically frustrating. WordPress organises content in a particular way that reflects WordPress conventions. Webflow has different strengths: reference fields between collections, multi-reference fields for many-to-many relationships, conditional visibility based on field values. A good Webflow CMS architecture takes advantage of these capabilities rather than simply replicating what existed before.
The practical implication is that the CMS architecture conversation needs to happen before build begins, not during it. The questions are: what content types does the business need, what relationships exist between them, what does the marketing team actually need to be able to update without developer assistance, and what level of CMS complexity can the team realistically manage. These questions are not technical questions. They are business and workflow questions that happen to have technical answers.
Getting this wrong is expensive to fix after launch. A collection architecture that creates the wrong relationships or leaves out necessary fields requires rebuilding the affected collections, remigrating the content and updating all templates. It is the kind of rework that makes migration projects go significantly over budget and timeline.
The plugin gap
WordPress functionality is largely delivered through plugins. Most established WordPress sites rely on plugins for forms, SEO metadata management, popup and lead capture, ecommerce if applicable, and a range of other functions that have no native equivalent in Webflow. The migration plan needs to account for every plugin dependency and identify either a Webflow-native replacement or a third-party integration.
For NZ businesses this often includes specific considerations. If the business is capturing leads through a form that connects directly to a CRM, that integration needs to be rebuilt in Webflow using either native Webflow forms with a Zapier or Make connection, or a third-party form provider that supports the required CRM. If the site uses a booking or scheduling plugin, Webflow does not have a native equivalent and a service like Calendly or Acuity needs to be embedded or integrated.
None of these are insurmountable. All of them need to be identified in the migration brief, not discovered during or after build. A migration that is scoped without a full plugin audit will miss dependencies that delay launch or require last-minute workarounds that compromise the implementation.
What changes for the marketing team
One of the most cited reasons for migrating to Webflow is giving the marketing team the ability to make content changes without developer involvement. This is a genuine Webflow advantage. It is also an advantage that requires onboarding and workflow design to realise.
Webflow's Editor is the interface the marketing team uses for content updates. It is different from the WordPress dashboard in ways that are initially counterintuitive for teams that have been in WordPress for years. CMS collection items are edited differently from static page content. Some visual design elements are not editable in the Editor and require Designer access. Nested symbols and global components update across the site when edited, which is powerful but requires the team to understand what they are touching.
The practical outcome for businesses that do not plan for this is a Webflow site where the marketing team is unable to make the updates they expected to be able to make without going back to the developer. The developer dependency that the migration was supposed to eliminate persists, just in a different context.
Planning for this means including a handover session and documentation in the migration scope, defining clearly which content is editable in the Webflow Editor and which requires Designer access, and establishing a workflow for content updates that matches how the team actually works. This is not complicated. It is also not included in most migration briefs because it is not a build task.
The six-month picture
A well-executed Webflow migration produces a site that is faster, easier to maintain, more visually capable and less dependent on developer time for routine updates. That picture is realistic. It requires that the migration be scoped to include URL mapping, content audit, CMS architecture decisions, plugin gap analysis and team onboarding.
A migration that skips those components produces a faster WordPress site on a different platform, with the same content problems, an incomplete redirect map, a CMS that does not match how the team works, and missing integrations that were discovered post-launch.
The businesses that get clean outcomes from Webflow migrations invest the upfront time to make the right decisions before build begins. The decisions are not technically demanding. They require honest assessment of what the current site is doing, what the business needs the new site to do, and what the team that manages it can realistically handle. Those are conversations worth having before the project starts rather than discovering the gaps after it launches.
