An enterprise CMS migration typically takes 3-6+ months, while builds with multiple regions, languages, or commerce integrations often run 6-12 months. A CMS, or content management system, is the platform where content types, publishing workflows, and integrations live, so migration means rebuilding that setup elsewhere. Small marketing sites can finish in 3-6 weeks, but enterprise teams should budget quarters, not weeks. The extra time covers audits, content restructuring, integration work, and post-launch checks.

Why do enterprise timelines run so long?
Large projects involve more stakeholders, languages, and connected systems than small-site moves. Storyblok reports in Storyblok's CMS migration guide that enterprise migrations with those factors commonly take 3-6+ months.
Scope grows again with regions and commerce. Core dna finds in Core dna's migration checklist that mid-market marketing sites need 3-6 months end-to-end, while enterprise builds with multiple regions, languages, or commerce integrations usually run 6-12 months.
What happens before content moves?
Teams start by auditing existing content and deciding what moves forward. Blend Interactive describes this triage as consolidating useful pages and archiving or removing stale pages before carrying anything into the new system. The old structure rarely fits the new CMS one-to-one.
Blend Interactive notes that teams must map content types and fields, then restructure, reformat, or rewrite content, with redirect planning in parallel. A documented enterprise case shows how detailed this audit gets. The team found 70-120 components and 30-50 variants before the contract, then analyzed pages for scripted versus manual migration.
How long does the content move take?
For large catalogs, the move itself spans months. In one enterprise example documented by eight25media, moving 5,000-13,000 pages took 4.5-5.5 months after the component audit and page-by-page analysis.
Scriptable pages move faster than pages needing manual rebuilds. That split explains why two sites with similar page counts can have different schedules.
- Audit pages, components, and variants
- Mark content as migrate, consolidate, archive, or remove
- Map old content types and fields to new models
- Flag scriptable pages versus manual pages
- Build URL mapping and redirect plan alongside content work
How do teams protect traffic and stability?
Poorly planned projects risk search visibility loss, broken integrations, workflow disruption, and performance problems. Dexa attributes that risk to the scope of the rebuild, which touches content models, integrations, publishing workflows, and performance architecture. Google advises preparing a URL mapping, using server-side redirects from old to new URLs, moving in smaller testable sections, and changing one major thing at a time.
Google states in Google's site move documentation that temporary ranking fluctuations lasting weeks or longer should be expected. Work continues after go-live. Blend Interactive describes post-launch tasks in Blend Interactive's migration services overview as verifying landing accuracy, testing integrations, training editors, monitoring search and redirects, and fixing issues surfacing in the first post-launch weeks. Keep redirect logs and ranking checks under daily review until those early fixes settle.
