A Webflow enterprise agency treats website migration from platforms like WordPress, Sitecore, Adobe Experience Manager, or Drupal as a multi-phase project, not a content copy-paste job. The work is methodical and designed to protect SEO equity while improving performance.

It starts with a discovery and audit phase. The agency inventories the existing site: every URL, content type, template, custom function, third-party integration, and piece of SEO metadata. Nothing gets assumed.

SEO preservation is where migrations live or die. The agency builds a detailed URL mapping and redirect strategy using 301 redirects, so the search authority your site has accumulated over years actually carries over to Webflow. Meta titles, descriptions, canonical tags, and structured data all come with it.

Content migration runs through a mix of Webflow's CMS import tools, custom scripts, and manual entry for anything complicated. Existing content fields get mapped to Webflow CMS collections carefully, because data integrity problems at scale are painful to fix after the fact.

Legacy platforms often have custom functionality that Webflow doesn't replicate out of the box. Form logic, gating mechanisms, member portals, search features. The agency rebuilds these using Webflow's native tools, custom code, or third-party integrations, depending on what actually makes sense for the use case.

Before anything goes live, there's a full round of cross-browser and cross-device testing, performance audits, accessibility scans, and integration checks. This phase takes longer than most clients expect, and it should.

Launch itself follows either a staged rollout or a hard cutover, with post-launch monitoring watching for traffic drops, crawl errors, and performance regressions. The goal isn't just a successful go-live. It's making sure nothing quietly breaks in the weeks after.
