How to Budget for a Kentico 13 to Xperience by Kentico Migration in 2026

Planning a Kentico 13 to Xperience by Kentico migration in 2026? Learn how to budget effectively, avoid common mistakes, and prepare for the end of Kentico 13 support. Discover key cost factors, redesign considerations, and expert tips from BizStream, a leading Kentico Gold Partner.

Why Budgeting Matters Now

As we close out 2025, many organizations running on Kentico 11, 12, or 13 are evaluating whether 2026 is the year to invest in migrating to Xperience by Kentico. Budget season is the perfect time to plan, but the process can feel daunting if you don’t know what to expect.

For Kentico 13 users in particular, the clock is ticking. Kentico has officially announced that support for Kentico 13 will end in December 2026. After that date, no new security patches, hotfixes, or official assistance will be available (see Kentico’s support lifecycle). This makes it critical to begin preparing well in advance. Waiting too long risks running your site on unsupported software.

A migration isn’t just a lift-and-shift; it’s a strategic project that impacts your website’s performance, digital marketing capabilities, and long-term scalability. A successful migration requires discovery, development, content migration, QA, and training, all of which can span many months. If you delay until 2026 to start planning, you may find yourself rushing the process, overspending for expedited work, or missing the chance to budget strategically.

By starting your budgeting discussions now, you give your team the flexibility to allocate resources wisely, phase the work effectively, and ensure a smooth transition well before the deadline.

BizStream’s Proven Process

1. Concept

The Concept phase lays the foundation for your migration. This is where strategy takes center stage. Together, we define:

  • Content Migration Strategy: What content should be carried forward, restructured, or retired?
  • Content Strategy: How will your content better support business goals moving forward?
  • SEO & GEO Strategy: How do we preserve (and improve) rankings while optimizing for generative engines?
  • User Experience & Redesign Decisions: Is this a straight migration, or should the migration also serve as a redesign or UX refresh?

In simple terms: if you’re wondering “What should my Kentico 13 migration budget include?”, the answer begins here, with strategy.

This stage creates a roadmap for what’s essential at launch versus what can evolve post-launch.

2. Design

In the Design phase, we translate strategic decisions into actionable plans:

  • Designing information architecture and page templates for Xperience by Kentico
  • Mapping out user experience (UX) improvements
  • Wire-framing and creating prototypes in Figma to describe the new visual experience
  • Planning integrations for CRM, ERP, or marketing automation systems
  • Addressing accessibility, performance, compliance, and governance needs early

3. Build

This is where the migration moves into development and implementation. While Kentico provides migration tooling for certain elements, such as page types, templates, and structured content, not everything transfers automatically. Key areas that require rebuilding include:

  • Custom Code: Any bespoke functionality written in Kentico 13 must be rewritten for the new .NET Core architecture.
  • Custom Integrations: Connections to third-party platforms (such as CRM, ERP, e-commerce, etc.) often require redevelopment.
  • Marketing Automation & Personalization: Legacy configurations may not carry over directly and require reimplementation.

One of the most common questions we hear is “Does a Kentico migration mean I have to rebuild everything?” The short answer: not everything, but many customizations do require redevelopment for the modern .NET Core architecture.

During this phase, we build the necessary components in Xperience by Kentico, migrate supported content, and validate performance across devices and browsers.

4. Evolve

A migration isn’t the end; it’s the beginning of a new growth cycle. In the Evolve phase, we:

  • Provide training for content editors and marketers
  • Monitor site stability after launch
  • Optimize based on analytics and user feedback
  • Plan for ongoing enhancements to support business goals long-term

By following our Concept, Design, Build, Evolve approach, your migration isn’t just a technical project; it’s a strategic opportunity to modernize, optimize, and future-proof your digital experience.

Key Budget Factors to Consider

When building your migration budget, it’s important to look beyond development hours. Several factors can significantly influence both the cost and long-term value of your project:

  • Scope of Customization: Heavily customized Kentico 13 sites require more effort than out-of-the-box implementations. Any bespoke features, workflows, or modules will need to be rebuilt for Xperience by Kentico’s modern architecture.
  • Third-Party Integrations: If your site connects to CRMs, ERPs, e-commerce, or marketing automation platforms, those integrations may need redevelopment or reconfiguration, adding to your budget.
  • Content Complexity: Migrating large volumes of structured content, media libraries, and SEO-critical assets takes time. A clear content migration strategy can help avoid unexpected costs.
  • Redesign Considerations: Many organizations ask whether to redesign during the migration or after. In most cases, redesigning during the migration is more cost-effective. Rebuilding templates, components, and layouts once (rather than migrating old designs only to rebuild them later) reduces duplicate effort and streamlines the project. It’s also the best opportunity to refresh user experience and accessibility without increasing overall project costs.
  • Licensing Costs: With Xperience by Kentico, you’ll need to decide between the new SaaS licensing model and a self-hosted option (such as hosting on Azure).
    • SaaS licensing simplifies infrastructure management, includes hosting, and often lowers long-term maintenance overhead.
    • Self-hosted licensing provides greater flexibility and control but introduces additional infrastructure, scaling, and maintenance costs that should be factored into your budget.
  • Internal vs. External Resources: Decide early whether your internal team will handle parts of the migration (such as content entry or QA) or whether you’ll rely fully on a partner. Outsourcing can reduce the burden on your team, but it will impact the budget.
  • Ongoing Optimization: A migration is not a one-time event. Budget for post-launch enhancements such as personalization, marketing automation, and new features to ensure your investment continues to deliver value.

In other words, if you’re asking “How much does a Kentico migration cost?”, the answer depends on your customization, integrations, content volume, redesign scope, licensing choice, and resourcing model.

Common Budgeting Mistakes to Avoid

Even well-intentioned migration projects can run into trouble if budgets don’t account for the realities of a Kentico 13 to Xperience migration. Here are some of the most common pitfalls:

  • Underestimating the Importance of Strategy
  • Underestimating Content Migration
  • Skipping the Discovery Phase
  • Choosing the Wrong Resourcing Model
  • Ignoring Training
  • Not Budgeting for Unknowns
  • Not Planning for Post-Launch

Put simply: the biggest mistake is treating a Kentico migration like a simple CMS upgrade. It’s a strategic rebuild that requires foresight, expertise, and planning.

How to Budget Smarter for 2026

Building a strong migration budget isn’t just about numbers; it’s about strategy, foresight, and setting your team up for long-term success. Here are practical steps to make sure your budget is realistic and resilient:

  1. Start Early
  2. Prioritize Strategy in the Early Phases
  3. Request a Detailed Estimate
  4. Evaluate Redesign Options
  5. Factor in Licensing Costs
  6. Be Cautious with “Cheaper” Options
  7. Include a Contingency Budget
  8. Allocate for Continuous Improvement

The direct answer to “When should I start budgeting for my Kentico 13 migration?” is: now. The earlier you begin, the more control you’ll have over costs, resourcing, and outcomes.

Frequently Asked Questions

Most migration projects take several months, depending on complexity, content volume, and custom features. Starting early allows for phased work rather than rushed execution.

Costs vary widely based on scope, integrations, and redesign. Simpler sites may budget in the tens of thousands, while highly customized enterprise implementations can reach six figures. The key is to plan for strategy, not just development.

Not strictly, but it’s usually more cost-effective to redesign during migration. Rebuilding once instead of twice saves money and improves UX immediately.

Your site will run on unsupported software, with no new security patches, updates, or official help. This exposes you to security risks, compliance issues, and higher emergency maintenance costs.
