The Sitecore XP Path Forward – Part 3: Upgrade, Migrate, Modernize

This guide helps IT leaders navigate Sitecore XP 8.x and 9.x upgrade paths—weighing whether to stay on XP, migrate to XM, or modernize to XM Cloud based on personalization needs, integration complexity, and business requirements. It lays out detailed migration and modernization steps for each pathway while stressing the strategic importance of upgrading before end-of-life support dates.

The Importance of Upgrading

Staying on an outdated version of Sitecore exposes organizations to security vulnerabilities, lack of support, and missed opportunities for new features. "Sitecore 8.x reached its end of life" on December 31, 2021, with versions 9.1 and under following on December 31, 2024. Versions 9.2 and 9.3 extend until December 31, 2025.

Upgrading to Sitecore 10.x ensures your organization benefits from:

  1. JSS and Headless Services in 10.2: Enable decoupled front-end applications using modern JavaScript frameworks
  2. GraphQL Authoring and Management API in 10.3: Facilitate efficient content querying and manipulation
  3. Headless SXA in 10.3: Support headless development for flexible front-end solutions
  4. Access to Experience Edge in 10.4: Scalable content delivery network for global content distribution
  5. Composable Martech Orchestration with Sitecore Connect in 10.4: Seamless integration of marketing technologies
  6. Sitecore Experience Commerce Support Note: XP 10.4 does not support Sitecore Experience Commerce (XC), requiring evaluation of alternative commerce solutions

Sitecore XP 10.4 shares the same core as XM Cloud, facilitating easier future modernization.

Evaluating Your Current Sitecore Instance

Before migration, thoroughly assess your current implementation, including:

  • Your digital presence and front-end technologies
  • Extent of personalization, analytics, and marketing automation integration
  • ASP.NET MVC dependencies and refactoring requirements
  • Deeply integrated personalization rules and marketing automation elements

Is XM Cloud Even a Viable Option for Your Business?

XM Cloud offers a SaaS-based approach with modern features but isn't suitable for every scenario. Key considerations include:

  1. Portals and Authenticated Experiences: Portals requiring authenticated log-in experiences are currently better suited for XP or XM
  2. Advanced Personalization and Experimentation: Basic XM Cloud capabilities may require additional solutions like Sitecore Personalize
  3. Use of Sitecore Forms: Sitecore announced a SaaS version of Forms in February, but deeply integrated custom forms require evaluation
  4. Integration Complexity: Modern API and microservices integrations work well; legacy systems with complex integrations need careful assessment
  5. Cloud-Native SaaS Solution: Evaluate whether SaaS aligns with your IT strategy, considering data residency, compliance, and on-premise preferences
  6. Internal Development Skillset: Assess whether your team possesses or can develop skills in JavaScript frameworks and Sitecore JSS

Migration Path if XM Cloud Isn't Viable for Your Business

Remain on XP or Migrate to XM?

When XM Cloud doesn't align with business needs, organizations typically choose between staying on XP or transitioning to the more composable XM solution.

Key Considerations:

  1. Personalization and xDB/xConnect: XM doesn't include xDB or xConnect; migration requires adopting Sitecore Personalize or alternative solutions
  2. Capability Utilization: Assess which XP features you actually use; organizations not leveraging advanced marketing automation may benefit from XM's composability
  3. Future Growth and Flexibility: Composable architecture with XM enables faster innovation and integration of additional SaaS tools
  4. Maintenance: XP's monolithic architecture becomes increasingly complex; XM offers streamlined integration paths with less complexity
  5. Experience Commerce (XC): XP 10.4 doesn't support XC, requiring evaluation of alternative commerce solutions for XM migration

Staying on XP

Upgrading to Sitecore 10.x ensures continued support and access to latest features. Note that direct upgrades from 8.x to 10.x require an incremental step through 9.x.

Modernization using JAMstack architecture and Experience Edge is optional. If XM Cloud becomes viable later, you can:

  • Refactor front-end code gradually
  • Leverage JAMstack architecture
  • Use Experience Edge
  • Explore SaaS solutions like CDP and Personalize

If hosted on-premise, evaluate whether cloud hosting solutions (Azure or Sitecore's Managed Cloud) better serve your needs.

Transitioning to a More Composable Solution with XM

XM enables leveraging Sitecore's capabilities while maintaining infrastructure flexibility—particularly beneficial for organizations not yet ready for full SaaS transition.

Key Steps for ASP.NET MVC Sites Upgrading to Sitecore 10.x:

1. Assessment and Planning:

Conduct thorough assessment inventorying components, customizations, integrations, and dependencies. Identify content, media, and data requiring migration. Evaluate custom code, modules, and third-party integrations that need refactoring or replacement.

2. Prepping for Migration:

Provision the XM environment and configure necessary settings. Develop detailed migration plan addressing timelines, milestones, responsibilities, risks, and mitigation strategies.

3. Content and Data Migration:

Use Unicorn or TDS to serialize and migrate content. Apply Sitecore PowerShell Extensions for necessary data transformation, ensuring accurate transfer without loss or corruption.

4. Refactoring Custom Code:

Modify render logic in components to align with XM capabilities. Replace XP-specific APIs and services with XM equivalents or third-party solutions. Update workflows and processes tied to XP features.

5. Integration:

Ensure external services and third-party integrations are XM-compatible. Adapt data flow and storage mechanisms for the new environment. Thorough testing prevents business process disruptions.

6. Testing and Validation:

Conduct comprehensive functional testing ensuring all features work as expected. Perform performance testing verifying the setup meets or exceeds current benchmarks. Execute User Acceptance Testing (UAT) validating system fulfills business requirements.

7. Deployment:

Deploy the refactored application to XM production environment post-testing. Monitor closely for issues and optimize for smooth operation.

Modernization Path if XM Cloud is Viable for Your Business

Starting Fresh with XM Cloud

Starting fresh leverages XM Cloud's latest capabilities including headless architecture, flexible deployment, and Experience Edge for optimized content delivery. This approach suits organizations seeking new digital experiences from the ground up.

If on XP 8.x and planning major redesign with new content strategy, starting fresh makes sense. Otherwise, upgrading to 10.x followed by XM Cloud transition proves time-consuming and costly.

Design/Content Refresh and Complete Re-architecture

This approach involves upgrading to Sitecore 10.x then gradually transitioning to XM Cloud capabilities, retaining existing business logic while improving front-end experience. Upgrading from 8.x to 10.x requires significant effort and incremental updates.
