Enterprise website migrations represent complex undertakings involving technical development, content transformation, stakeholder coordination, and risk management. Realistic timeline expectations prevent frustration and enable appropriate resource allocation ensuring successful outcomes.
Migration complexity determines baseline timeline requirements. Small implementations migrating 20-50 pages with standard content types, minimal custom functionality, and straightforward URL structures complete in 6-8 weeks. These projects benefit from template-driven approaches, automated content migration tools, and simplified approval chains. Medium complexity migrations spanning 50-150 pages with moderate custom functionality, CRM integrations, multiple content types, and URL restructuring require 8-12 weeks accommodating additional architecture complexity, custom development, and expanded testing requirements. Large enterprise migrations exceeding 150-200 pages with sophisticated custom functionality, extensive third-party integrations, complex approval hierarchies, and multi-stakeholder coordination extend 12-16 weeks or longer. The largest migrations occasionally span 20-24 weeks when involving complete rebranding, significant information architecture overhauls, or phased launches across multiple properties.
Discovery and audit phase (1-2 weeks) initiates projects, establishing foundation for successful execution. Teams conduct comprehensive content audits cataloging all existing pages, assets, and functionality, perform technical analysis of current platform identifying custom features requiring recreation or alternative approaches, facilitate stakeholder workshops aligning on business objectives and success criteria, review existing analytics establishing performance baselines for post-launch comparison, conduct SEO analysis documenting current rankings and traffic sources requiring preservation, and create detailed project plans with milestones, responsibilities, and timeline projections. Rushing discovery creates downstream problems, inadequate planning leads to scope creep, missed requirements, and timeline extensions. Thorough discovery proves investment preventing larger problems later.
Design and architecture phase (2-4 weeks) transforms audit findings into concrete implementation plans. Design teams create wireframes defining page layouts and content hierarchy, develop design systems establishing reusable components and brand consistency, prototype key user journeys testing flow and conversion paths, and define responsive behaviors ensuring mobile excellence. Simultaneously, technical architects design CMS Collection structures accommodating content types and relationships, plan integration architectures connecting Webflow with existing systems, map URL structures and redirect requirements preserving SEO equity, and document technical specifications guiding development. Design and architecture proceeds in parallel when resourcing permits, compressing overall timeline. Extended design exploration or extensive revision cycles extend this phase, organizations minimizing design iteration through clear initial direction and decision-making authority accelerate timelines.
Development and CMS build phase (3-6 weeks) constitutes the core technical implementation work. Developers build component libraries translating designs into functional Webflow elements, construct page templates creating reusable structures for content types, implement CMS Collections establishing content management infrastructure, develop custom code implementing functionality beyond native Webflow capabilities, integrate third-party services connecting CRM, marketing automation, analytics, and specialized tools, and implement responsive behaviors ensuring cross-device consistency. Development duration varies dramatically with complexity, straightforward template-driven builds complete rapidly while custom interactive features, sophisticated animations, or complex integrations extend timelines. Organizations providing clear specifications, minimizing mid-stream requirement changes, and maintaining accessible subject matter experts for questions achieve faster development cycles.
Content migration and QA phase (2-3 weeks) transfers content from legacy systems and validates implementation quality. Content teams migrate textual content from WordPress, Drupal, or legacy CMS to Webflow Collections, transfer and optimize images compressing files and updating references, implement redirects mapping old URLs to new Webflow equivalents preserving SEO equity, and validate metadata ensuring title tags, descriptions, and schema markup transfer correctly. Simultaneously, QA processes test cross-browser compatibility ensuring consistent experiences across browsers, validate responsive design confirming mobile/tablet functionality, test form submissions and integrations verifying data flows correctly, conduct accessibility audits ensuring WCAG compliance, and perform security reviews confirming appropriate configurations. Content preparation significantly influences timeline, organizations pre-cleaning content, optimizing images before migration, and conducting content audits removing obsolete material accelerate this phase substantially. Organizations approaching migration with raw unoptimized content face extended timelines during this phase.
Launch preparation and deployment (1-2 weeks) orchestrates final coordination activities before public launch. Teams conduct final stakeholder reviews ensuring approval from all required parties, implement DNS configuration preparing domain transfer to Webflow hosting, schedule launch timing coordinating with marketing activities and traffic patterns, establish monitoring dashboards tracking performance metrics post-launch, and prepare rollback procedures documenting recovery processes if launch issues emerge. Conservative organizations maintain extended parallel running where old and new sites operate simultaneously while monitoring new site performance before complete cutover. Post-launch monitoring (1-2 weeks following deployment) tracks SEO performance confirming rankings stabilize, validates redirect functionality ensuring no 404 errors from broken redirects, monitors form submissions confirming lead capture operates correctly, and addresses minor issues emerging under real traffic loads.
Internal factors influence timelines more than technical complexity in many enterprises. Stakeholder availability for reviews and approvals creates delays when decision-makers remain inaccessible for weeks. Content readiness, whether content requires creation, cleaning, or optimization, dramatically affects timelines. Approval bottlenecks where multiple layers review every decision extend all phases. Change management where mid-project requirement additions expand scope creates timeline extensions. Organizations minimizing these factors through dedicated project leadership, content preparation before technical work begins, streamlined approval processes, and scope discipline achieve dramatically faster migrations than equivalent-complexity projects without these disciplines.
Hubilo, a Series C event-technology company, completed full WordPress to Webflow Enterprise migration including 45 core marketing pages and 400+ blog posts in exactly 90 days (3 months) despite also executing complete rebrand simultaneously. This aggressive timeline proved achievable through several factors: executive mandate establishing urgency, dedicated project leadership coordinating cross-functional work, pre-prepared content architecture before technical work began, parallel work streams enabling simultaneous design, development, and content preparation, streamlined approval chains with empowered decision-makers, and experienced agency partner (Zabal Media) executing efficiently. The project demonstrates that focused organizations with proper resource allocation achieve ambitious timelines for complex migrations.

Small simple sites occasionally migrate in 4-5 weeks under ideal conditions, pre-prepared content, streamlined approvals, minimal custom development. However, rushing migrations increases error risk and typically proves counterproductive. Conservative timelines enable quality work.
Primary delays include stakeholder unavailability extending approval cycles, content unreadiness requiring preparation during migration, scope expansion adding unanticipated requirements mid-project, integration complexity exceeding initial estimates, and vendor dependencies where third-party systems delay integration implementation.
Ideally yes, timing migrations during low-traffic periods reduces stakes if launch issues emerge. However, migrations span months, waiting for perfect timing sometimes delays indefinitely. Balance timing considerations with business readiness and resource availability.
Yes, phased launches reduce complexity and risk. Common approaches include launching homepage and key pages first, migrating blog separately, or implementing region-by-region for multinational sites. Phased approaches extend overall project duration but reduce single-launch complexity.
Budget 2-4 weeks post-launch for monitoring, minor adjustments, and addressing issues emerging under real traffic. Most critical monitoring occurs in first week when SEO fluctuations, redirect errors, or integration issues surface most prominently.
