Sitefinity to Webflow
Move from a .NET-based legacy DXP to a modern, globally distributed Webflow architecture that scales effortlessly.

Is your enterprise's digital growth being stifled by the technical overhead of Progress Sitefinity? While Sitefinity has long served as a standard .NET CMS for mid-to-large organizations, its heavy infrastructure requirements, complex "Widget" architecture, and the constant need for specialized C# developers have become significant bottlenecks in 2026. Forward-thinking leaders are now decoupling their front-end experiences from these legacy monolithic systems. This guide by Flowtrix details our specialized process for migrating your enterprise presence from Sitefinity to Webflow, enabling you to slash your TCO, eliminate "IT-only" update cycles, and launch high-performance experiences that meet the rigorous security and speed demands of the modern web.
Why Migrate from Sitefinity to Webflow?
In 2026, the website should be a marketing asset, not a backend engineering project. Here is why enterprise leaders are choosing the Flowtrix migration path.
1. Reclaiming Marketing Independence
Sitefinity’s greatest weakness in a modern marketing context is its "Authoring Friction." Creating a new page layout or modifying a "Widget" often requires specialized .NET developers to work within Visual Studio, modify templates, or handle complex synchronization tasks. In Webflow, your designers and marketers build and publish visually. At Flowtrix, we build a Core Component Library in Webflow that allows your non-technical teams to launch campaign pages in hours, not weeks, without a single Jira ticket for the dev team.
2. Drastic Reduction in Total Cost of Ownership (TCO)
The annual licensing fees for Sitefinity are significant, often compounded by the cost of Windows Server maintenance, SQL Server licenses, and specialized .NET talent. Webflow is a fully managed SaaS platform. By migrating, you eliminate the need for server patching, .NET version upgrades, and expensive legacy talent recruitment. Flowtrix helps enterprises reallocate these six-figure budgets toward digital innovation and customer acquisition.
3. Performance & The "Core Web Vitals" Edge
Sitefinity sites often suffer from "DOM depth" and excessive server-side rendering that creates significant latency. This is a critical failure in the 2026 "Speed-as-a-Ranking-Factor" era. Webflow generates clean, semantic HTML5 served from the edge via AWS and Fastly. Our migrations consistently result in 3x–5x faster load times, which significantly improves SEO and conversion metrics.
4. Modern Security Without the Overhead
Sitefinity requires constant manual patching of the CMS and the underlying Windows/IIS infrastructure to remain secure against automated attacks. Webflow handles the security of the infrastructure, hosting, and CMS at the platform level. It is SOC-2 Type II compliant, providing an enterprise-grade security "shield" without any manual effort from your internal IT team.
Sitefinity vs. Webflow: The 2026 Reality
The Strategic Shift for Enterprise Leaders
Moving from "Monolithic Portals" to "Composable Experiences"
In 2026, the trend is toward Composable Digital Experiences. Enterprises are moving away from "all-in-one" suites that try to do everything (poorly) and moving toward specialized, high-performance tools.
The "Best-of-Breed" Revolution
Sitefinity attempts to be a CMS, an analytics suite, and an email tool all at once, leading to significant "feature bloat." By moving to Webflow, Flowtrix helps you build a modular stack. You use Webflow for your high-performance storefront, and integrate specialized tools for your specific needs (like VWO for testing or Algolia for search). This means you aren't tied to a single legacy vendor for every function.
Solving the "Technical Debt" Crisis
Legacy Sitefinity instances often carry years of technical debt, unoptimized C# code, outdated templates, and broken "Sync" configurations. A migration to Webflow by Flowtrix is a "Digital Reset." We sanitize your content, modernize your CSS architecture (using the Client-First framework), and deliver a clean, documentation-ready site built for the next decade.
The Webflow Evolution for Enterprise Data
Scaling Complex Content with Professional Precision
Webflow is now a battle-tested enterprise platform capable of handling the deep content structures previously reserved for heavy .NET repositories.
- Advanced Relational CMS: We replicate Sitefinity "Content Types" and "Taxonomies" using Webflow CMS Collections. We maintain the relational integrity of your data, ensuring your "Solution-to-Resource" and "Author-to-Case-Study" links remain intact.
- Wized for Authenticated Experiences: For sites that require the secure "logged-in" portals or member areas Sitefinity is known for, we use Wized. This allows us to build secure web applications on top of the Webflow front-end, connecting to your internal APIs or databases.
- Enterprise SSO & Governance: We integrate your corporate Single Sign-On (SSO)—Okta, Azure AD, or Ping—ensuring your IT department maintains 100% control over site access and publishing workflows.
- Global Design Systems: We implement "Variables" and "Components" in Webflow, creating a single source of truth for your brand. This ensures that even as you scale to thousands of pages, your global brand identity remains perfectly consistent.
The Flowtrix 10-Step Sitefinity Migration Protocol
Migrating an enterprise site from Sitefinity requires a surgical approach to data mapping and front-end re-architecture.
1. Discovery & Content Schema Audit
We deconstruct your Sitefinity "Module Builder" structures. We identify which legacy "Widgets" are critical and which can be replaced by native, high-performance Webflow features.
2. Global SEO & Redirect Mapping
Legacy Sitefinity URL structures can be non-intuitive. We build a comprehensive 301 Redirect Manifest, mapping thousands of legacy URLs to their new Webflow equivalents to protect your search equity.
3. Data Extraction & Sanitization (ETL)
We extract your content from the SQL Server database. We sanitize the HTML, removing ".NET-specific" tags and inline styles, and transform the data into clean JSON/CSV for Webflow import.
4. Architecting the Visual Identity
Flowtrix architects your new site using a professional framework (like Client-First). We build a centralized "Style Guide" in Webflow that replaces Sitefinity’s complex CSS libraries, making global updates instant.
5. Media Asset & Metadata Migration
We migrate your digital assets from the Sitefinity libraries, optimizing images for WebP and ensuring all metadata and alt-tags are perfectly preserved for accessibility and SEO.
6. Functional Replication (Search & Forms)
We replace Sitefinity’s native search with Algolia and its form engine with native Webflow forms synced directly to your enterprise CRM (Salesforce, HubSpot, or Microsoft Dynamics).
7. SSO & Security Configuration
We work with your IT team to configure security headers and SSO access, ensuring the site meets all corporate compliance and data residency standards.
8. UAT & Accessibility Pass
We run the site through rigorous testing, including WCAG 2.1 accessibility audits and cross-browser performance benchmarks to ensure it is "Enterprise-Ready."
9. Internal Team Empowerment
We provide custom, role-based training. Your designers learn the "Designer," while your content editors learn the "Visual Editor," replacing a complex .NET manual with intuitive video guides.
10. Managed DNS Cutover
We handle the technical transition at the edge. Because Webflow is natively distributed, your site "goes live" globally almost instantly, eliminating the stress of "traditional" enterprise deployment windows.
Overcoming Sitefinity Migration Challenges
- "Can Webflow handle our thousands of pages?" : Yes. On Webflow Enterprise, we use modular architectures and "Component-Based" builds to manage vast libraries without compromising Designer performance.
- "What about our custom C# logic?" : We audit your logic. Most of it is replaced by lightweight JavaScript or modern APIs. For heavy backend processes, we use Webflow Logic or external serverless functions.
- "Will we lose our multi-language translations?" : No. Flowtrix uses Webflow Localization to mirror your global presence. It is significantly faster and more intuitive to manage than Sitefinity’s localization system.
- "Is Webflow secure enough for regulated industries?" : Absolutely. Webflow is SOC-2 Type II compliant and is used by major financial and healthcare institutions. It provides a more secure "closed-loop" environment than a manually managed .NET stack.

We Also Migrate From
Can Webflow handle Sitefinity-scale content?
Webflow Enterprise supports massive CMS item counts (up to 100k+). For huge archival requirements, we implement a "Hybrid" setup where core marketing lives on Webflow and deep history is served via a headless connection.
What happens to our Sitefinity Widgets?
We translate your Sitefinity MVC Widgets into native Webflow Components. This replaces hard-coded .NET logic with a visual, drag-and-drop building experience that is 10x easier for your team to maintain.
Will our enterprise security (SSO) be preserved?
Yes. Webflow Enterprise features native support for SAML-based Single Sign-On (SSO). We integrate your existing IAM solutions (Azure AD, Okta) to ensure secure internal access.
How long does a Sitefinity migration typically take?
Given the complexity of .NET portal architectures, a migration typically spans 10 to 14 weeks, covering discovery, data sanitization, visual building, and post-launch support.
