Platform migration to a Webflow system you can run
Website migration is the structured process of moving content, relationships, and behavior from a legacy platform into a governable Webflow system — while protecting SEO equity, reducing accessibility exposure, and giving your team a CMS they can run without constant contractor rescue.

When it’s time to migrate (not patch)
Patches buy months; they rarely fix architecture. If several of these are true, you’re past “incremental updates.”
- Site or CMS is 3+ years old in meaningful ways (stack, patterns, content model).
- Plugin-heavy WordPress, brittle Drupal, or lock-in on Duda/Wix — or an inherited “custom” setup no one documents.
- Accessibility status is unknown, or audits keep reopening the same issues.
- Content is hard to publish — editors work around the CMS instead of with it.
- No single source of truth for structure, URLs, or component behavior.
- SEO instability: redirects missing, duplicate URLs, thin templates after years of edits.
- Inherited Webflow that was layout-first — collections and classes don’t match how the org works now.
Why migration beats another round of fixes
Technical debt compounds: every emergency fix adds exceptions, and exceptions become the system. Accessibility exposure doesn’t shrink when you decorate bad patterns — it shifts to forms, PDFs, and new content types.
Migration is a chance to normalize content into collections, fix relationships, and ship accessible components by default — then validate and govern so the same problems don’t return in six months.
How we run platform migrations
- Platform audit — inventory CMS, integrations, URL patterns, and failure modes.
- Content inventory & mapping — what moves, what merges, what retires; URL mapping draft.
- Accessibility risk review — exposure framing (CES-aligned), not a fake “pass/fail” sticker.
- CMS architecture design — collections, fields, roles, component boundaries.
- Structured rebuild in Webflow — build to the model, not the old templates.
- Validation & launch governance — QA, redirects, monitoring handoff.
SEO preservation is structural work
- URL mapping and redirect strategy (not “we’ll figure it out at launch”).
- Metadata and indexation plan; avoid mass duplicate routes.
- Structured content so templates earn queries — not one-off pages.
- Post-launch checks for crawl errors and analytics continuity.
Accessibility in the rebuild — not a post-launch scramble
We align to WCAG 2.2 AA as an engineering target: components, forms, media, and content workflows. Framing uses exposure language (see CES) — not legal advice.
Common failure modes
Failure
Our counterweight
Who gets the most from this service
- Nonprofits and associations with board or grant visibility on digital and accessibility.
- Mid-size orgs without a full in-house engineering bench.
- Teams that outgrew a commodity build and need a platform, not a reskin.
When we’re not the right partner
- You need a visual-only refresh with no appetite to fix structure or CMS.
- Budget assumes “move every page 1:1” with zero discovery — that’s how migrations fail.
- Overlay-only accessibility expectations — we don’t substitute widgets for engineering.
- Unrealistic timelines that skip inventory and URL mapping.
Governance is what keeps the system honest after launch
Governance is the practice layer: how content types change, who approves them, how releases run, and what documentation exists so the team is not dependent on tribal knowledge. BM Web Studio does not sell governance as a separate service line — it is embedded in platform migration and handoff, and reinforced through the Approach page
- Content modeling rules — when to add a collection vs a field vs a category
- Roles & workflow — who can publish, who approves structural changes
- Documentation — editor handbook, component usage, do / don’t for Webflow
- Change management — structural updates without breaking dependent templates
- Alignment with QA — what gets validated when templates change
Highest leverage during or immediately after migration — while patterns are fresh. Governance without authority to fix structure usually stalls; migration work is the natural container.
Plan from reality — not from a template proposal
Frequently Asked Questions
How long does a website migration take?
Depends on content volume, URL complexity, integrations, and validation scope; assessment gives an indicative tier.
Will I lose SEO during migration?
Not if redirects, mapping, and content modeling are treated as core deliverables.
How much does migration cost?
Scoped from audit + model; calculator and discovery narrow the range.
Is Webflow better than WordPress?
Depends on editorial needs and governance; we’re pro-outcome: maintainable structure and accessibility path.
Can you migrate from Drupal to Webflow?
Yes, with explicit content extraction and normalization planning.
What happens to existing URLs?
Mapped, redirected, and tested; exceptions documented.
How do you preserve accessibility?
Component-level requirements, remediation backlog, validation — not a single audit PDF.
What happens to my content?
Extracted, cleaned, and modeled — not blindly imported.
