COMMON OBJECTIONS ABOUT SITECORE TO SANITY MIGRATION

We understand that migrating from an established CMS like Sitecore to a headless platform like Sanity raises questions. Let’s address the most common concerns we hear from enterprises considering this migration:

1. Sitecore offers robust personalization features. Can Sanity match that?

Sitecore’s Experience Platform provides built-in personalization, but it comes with significant complexity and cost. With Sanity, you have the flexibility to implement personalization at the frontend layer using best-of-breed tools.

This approach gives you more control, better performance, and the ability to switch personalization providers without CMS lock-in.

2. Our team is trained on Sitecore. How difficult is the transition?

Sanity Studio is intentionally designed to be intuitive. Most content editors become productive within hours, not weeks.

For developers, if your team knows JavaScript, they’re already equipped to work with Sanity. The schema-driven approach is more familiar to modern developers than Sitecore’s .NET architecture.

Plus, we provide comprehensive training programs tailored to your team’s roles—ensuring a smooth transition for everyone from editors to administrators.

3. Will we lose our existing content and SEO rankings?

Absolutely not. A properly executed migration includes:

Most of our clients see maintained or improved search rankings post-migration due to Sanity’s superior performance and clean URL structures.

4. How long does a Sitecore to Sanity migration take?

Migration timelines vary based on:

Typical enterprise migrations take 12–20 weeks, broken down as:

Starting with a phased approach can reduce initial timeline and risk.

5. What about multisite and multilingual capabilities?

Sanity excels at both:

Multisite management: Sanity’s flexible schema lets you manage multiple sites from one Studio with shared or site-specific content. You can structure datasets to isolate content or share it across properties.

Multilingual support: Use Sanity’s official internationalization plugin or structure language variants in your schema. Unlike Sitecore’s rigid language management, Sanity gives you complete control over translation workflows.

Many clients find Sanity’s approach more flexible and easier to manage than Sitecore’s multisite architecture.

6. Sitecore integrates with our existing MarTech stack. Will Sanity?

One of Sanity’s greatest strengths is its open, API-first architecture. It integrates seamlessly with:

Because Sanity doesn’t try to be an all-in-one solution, you can choose best-of-breed tools for each function and integrate them exactly how you need.

7. What if we need custom functionality?

Sanity is highly extensible through:

Unlike Sitecore’s rigid architecture, Sanity’s JavaScript-based extensibility means your developers can build exactly what you need without fighting the framework.

8. How do we handle workflows and approvals?

Sanity provides flexible workflow capabilities through:

Many clients build sophisticated approval workflows using Sanity’s extensibility—often simpler and more tailored than Sitecore’s workflow engine.

9. Who should handle our migration—internal team or experts?

The answer depends on:

Benefits of working with migration experts:

At Multidots, we’ve successfully migrated dozens of enterprise sites from traditional CMS platforms to modern headless architectures, including Sanity. Our team brings expertise in both Sitecore and Sanity, ensuring nothing is lost in translation.

10. What’s the ROI of moving to Sanity?

According to a recent Forrester Total Economic Impact™ study, enterprises migrating to Sanity see an ROI of 272% with a payback period of less than 6 months.

Immediate cost savings:

Productivity gains:

Performance and reliability improvements:

Long-term benefits:

Real-world results:

Organizations in the Forrester study reported being able to make 18,000 content changes annually that previously required developers, while commercial teams now make 25,000 changes themselves. One company scaled from managing 2,000 hotels once a year to managing 40,000 hotels multiple times per year with the same team size.

The study found that enterprises experience benefits of $1.7 million over three years versus costs of $469,000, resulting in a net present value of $1.3 million.

Common migration objectives:

How will success be measured?

1.6 Choose Your Migration Approach

You have three primary approaches for migrating from Sitecore to Sanity:

Full Migration (Big Bang): Move all content at once. Best for smaller sites needing urgent Sitecore exit. Fastest but higher risk.

Phased Migration (Gradual): Migrate sections incrementally with testing between phases. Best for large, complex sites. Lower risk, longer timeline.

Hybrid Approach (Parallel): Run both systems simultaneously during transition. Best for mission-critical sites requiring zero downtime. Most complex but safest.

Our recommendation: For most enterprises, a phased migration offers the best balance of risk management and efficiency.

1.7 Who Should Handle the Migration?

Deciding whether to handle your Sitecore to Sanity migration in-house or hire experts depends on several factors:

Consider Your Internal Team If:

STEP 2: GETTING READY FOR THE MIGRATION

With a high-level migration strategy in place, you’re ready to tackle the necessary preparations to ensure a smooth process. This preparation phase is critical—it prevents data loss, maintains SEO equity, and ensures all stakeholders are aligned.

2.1 Backup Your Sitecore Environment

First things first—always, always back up your data. This is your safety net should anything go wrong during migration.

Here’s how to create comprehensive backups of your Sitecore environment:

Content backup:

  1. Log into Sitecore as an administrator
  2. Navigate to Control Panel → Database
  3. Use Package Designer to create packages of your content tree
  4. Export packages for each major content area
  5. Store packages in multiple secure locations

Media Library backup:

  1. Navigate to Control Panel → Localization → Export Languages
  2. Select your Media Library for export
  3. Download all media assets with metadata
  4. Store assets organized by folder structure
  5. Document asset relationships and usage

Configuration backup:

Database backup:

Pro tip: Test your backups by restoring them to a development environment before proceeding with migration. Store backups in multiple locations, including secure cloud storage with encryption enabled.

2.2 Content Inventory and Audit

A thorough content inventory helps you understand exactly what needs to be migrated and how it should be organized in Sanity.

What to inventory:

Content types and volumes:

Content relationships:

Custom functionality:

Content quality assessment:

Use tools like Screaming Frog or Sitebulb to crawl your Sitecore site and generate comprehensive reports.

Looking to take control of your content migration?

Use our Content Audit Template to track all your content systematically. This template includes tabs for different content types and fields for organizing, prioritizing, and streamlining every step.

Pro tip: This is an excellent opportunity to clean up your content. Don’t migrate content you no longer need—it just adds complexity and cost.

2.3 Snapshot of Page Rankings & Performance

Before migrating, capture your current SEO and performance metrics. This gives you a baseline to compare against after migration and helps you prioritize high-value pages.

Tools to capture your pre-migration data:

Most importantly, export a complete list of your top-performing pages by organic traffic. These pages will need special attention during migration to preserve their SEO value.

2.4 Analyze Sitecore Content Structure

Understanding how your content is organized in Sitecore is crucial for planning its Sanity structure.

Document your content tree hierarchy and how content is nested. List all Sitecore templates, their field types, and any template inheritance chains. Catalog rendering components and their data sources. Map your taxonomy structures including categories, tags, and custom classifications.

This analysis ensures your Sanity schema maintains logical organization while leveraging Sanity’s more intuitive and flexible content modeling approach.

2.5 Document Integrations and Dependencies

Your Sitecore site doesn’t exist in isolation—it’s part of a broader technology ecosystem. Documenting these connections ensures business continuity.

What tools to document:

For each integration, document:

Most integrations can be migrated or replicated with Sanity, often with simpler, more maintainable implementations.

STEP 3: SET UP SANITY

After mapping out your migration strategy, it’s time to establish your Sanity environment. This step is crucial as it lays the foundation for how your content will be structured, who can access it, and how users will interact with it.

A properly configured Sanity setup ensures that you’re not just replicating your Sitecore website, but actually enhancing it by leveraging Sanity’s flexibility, performance, and user-friendly features.

3.1 Install and Initialize Sanity

Let’s get your Sanity project up and running.

Installation steps:

1. Install Sanity CLI:

2. Create a new Sanity project:

sanity init

You’ll be prompted to:

Start Sanity Studio locally:

cd my-sanity-project

sanity start

Your Sanity Studio will be available at http://localhost:3333

Pro tip: Start with a blank schema rather than a template. This gives you complete control over your content model from the beginning.

3.2 Content Modeling and Schema Design

Content modeling is where Sanity truly shines. Unlike Sitecore’s rigid templates, Sanity’s schema-driven approach gives you complete flexibility.

Best practices for schema design:

Start with document types:

Think of documents as your primary content types (Pages, Articles, Authors, Products, etc.).

// Example: Article schema
export default {
  name: 'article',
  title: 'Article',
  type: 'document',
  fields: [
    {
      name: 'title',
      title: 'Title',
      type: 'string',
      validation: Rule => Rule.required()
    },
    {
      name: 'slug',
      title: 'Slug',
      type: 'slug',
      options: {
        source: 'title',
        maxLength: 96
      }
    },
    {
      name: 'author',
      title: 'Author',
      type: 'reference',
      to: [{type: 'author'}]
    },
    {
      name: 'publishedAt',
      title: 'Published at',
      type: 'datetime'
    },
    {
      name: 'body',
      title: 'Body',
      type: 'blockContent'
    }
  ]
}

Map Sitecore templates to Sanity schemas:

Sitecore ConceptSanity Equivalent
TemplateDocument Schema
FieldSchema Field
Standard ValuesDefault Values in Schema
Rendering ParametersComponent Props/Objects
Base TemplatesSchema Composition
Insert OptionsReferenced Types

Use structured content (Portable Text):

Sanity’s Portable Text is a rich text format that’s portable across platforms—unlike Sitecore’s HTML-based rich text.

{
  name: 'body',
  title: 'Body',
  type: 'array',
  of: [
    {
      type: 'block',
      marks: {
        annotations: [
          {
            name: 'link',
            type: 'object',
            fields: [
              {
                name: 'href',
                type: 'url'
              }
            ]
          }
        ]
      }
    },
    {
      type: 'image',
      options: {hotspot: true}
    }
  ]
}

Implement content references:

Sanity’s reference fields create relationships between documents—similar to Sitecore’s Droptree or Multilist fields but more flexible.

{
  name: 'relatedArticles',
  title: 'Related Articles',
  type: 'array',
  of: [{type: 'reference', to: [{type: 'article'}]}]
}

Create reusable objects:

For content blocks that appear across multiple document types:

export default {
  name: 'seoMetadata',
  title: 'SEO Metadata',
  type: 'object',
  fields: [
    {name: 'metaTitle', type: 'string'},
    {name: 'metaDescription', type: 'text'},
    {name: 'openGraphImage', type: 'image'}
  ]
}

Implement content references:

Sanity’s reference fields create relationships between documents—similar to Sitecore’s Droptree or Multilist fields but more flexible.

{
  name: 'relatedArticles',
  title: 'Related Articles',
  type: 'array',
  of: [{type: 'reference', to: [{type: 'article'}]}]
}

Create reusable objects:

For content blocks that appear across multiple document types:

export default {
  name: 'seoMetadata',
  title: 'SEO Metadata',
  type: 'object',
  fields: [
    {name: 'metaTitle', type: 'string'},
    {name: 'metaDescription', type: 'text'},
    {name: 'openGraphImage', type: 'image'}
  ]
}

3.3 Set Up User Roles and Permissions

Sanity provides role-based access control (RBAC) to manage who can do what in your project.

Default roles:

Custom roles:

For more granular control, create custom roles in your Sanity project settings:

// Example: Custom role for "Contributor"
{
  name: 'contributor',
  title: 'Contributor',
  permissions: [
    {
      action: 'create',
      documentTypes: ['article', 'author']
    },
    {
      action: 'update',
      documentTypes: ['article'],
      filter: '_id in path("drafts.**")'  // Can only edit drafts
    }
  ]
}

Pro tip: Start with broad permissions and narrow them down based on actual usage patterns. It’s easier to restrict later than to troubleshoot permission issues early on.

3.4 Configure Environments and Datasets

Sanity supports multiple datasets for different environments (production, staging, development).

Dataset configuration:

Create datasets for each environment:

sanity dataset create staging

sanity dataset create development

Set up Cross-Origin Resource Sharing (CORS) origins:

Configure which domains can access your Sanity content:

  1. Go to your project settings at sanity.io/manage
  2. Navigate to API settings
  3. Add CORS origins for your frontend applications:

Configure API tokens:

Generate tokens for different purposes:

3.5 Integrate with Your Frontend

Sanity is framework-agnostic, but here are the most common setups:

Next.js Integration (Most Popular)

Install dependencies:

npm install next-sanity @portabletext/react @sanity/image-url

Create Sanity client:

// lib/sanity.js
import {createClient} from 'next-sanity'

export const client = createClient({
  projectId: 'your-project-id',
  dataset: 'production',
  apiVersion: '2025-01-01',
  useCdn: true,
})

Fetch content:

import {client} from '../lib/sanity'

export async function getStaticProps() {
  const articles = await client.fetch(`
    *[_type == "article"] | order(publishedAt desc) {
      title,
      slug,
      author->{name},
      publishedAt
    }
  `)

  return {
    props: {articles}
  }
}

Enable Preview Mode

Sanity’s real-time preview lets editors see changes before publishing:

1. Set up preview in Next.js:

// pages/api/preview.js
export default function preview(req, res) {
  res.setPreviewData({})
  res.redirect(req.query.slug)
}

2. Configure in Sanity Studio:

// sanity.config.js
import {defineConfig} from 'sanity'

export default defineConfig({
  // ... other config
  plugins: [
    // Add preview plugin
    previewPlugin({
      previewUrl: 'https://yoursite.com/api/preview'
    })
  ]
})

3.6 Implement Internationalization (if needed)

For multilingual sites, Sanity offers flexible i18n options:

Option 1: Document-level translations

Create separate documents for each language:

{
  name: 'article',
  title: 'Article',
  fields: [
    {
      name: 'language',
      type: 'string',
      options: {
        list: [
          {title: 'English', value: 'en'},
          {title: 'Spanish', value: 'es'},
          {title: 'French', value: 'fr'}
        ]
      }
    },
    // ... other fields
  ]
}

Option 2: Field-level translations

Use Sanity’s internationalization plugin:

npm install @sanity/language-filter
{
  name: 'title',
  type: 'object',
  fields: [
    {name: 'en', type: 'string'},
    {name: 'es', type: 'string'},
    {name: 'fr', type: 'string'}
  ]
}

Pro tip: Choose your i18n approach based on how much content varies between languages. If translations are straightforward word-for-word, use field-level. If content structures differ significantly by language, use document-level.

STEP 4: LAUNCH

Now comes the exciting part—actually migrating your content and launching your new Sanity-powered site. This phase requires careful coordination and thorough testing to ensure everything works perfectly.

4.1 Content Migration from Sitecore

Content migration is the heart of your Sitecore to Sanity transition. Let’s break this down into manageable steps.

Export Content from Sitecore

Step 1: Log in to Sitecore as an administrator

Step 2: Navigate to Control Panel → Localization → Export Languages

Step 3: Select language and root content item

Choose the top-level Sitecore item that contains all the content you want to export.

Step 4: Complete the export

Wait for the process to complete and download the XML file.

Step 5: Export additional languages

Repeat the process for each language variant if your site is multilingual.

Step 6: Store XML files securely

Save the exported XML files in a secure location for transformation.

Transform Sitecore XML to Sanity Format

Sitecore exports content in XML format, which needs to be transformed into Sanity-compatible JSON. This typically requires custom scripts.

Example transformation script structure:

const fs = require('fs');
const xml2js = require('xml2js');
const sanityClient = require('@sanity/client');

const client = sanityClient({
  projectId: 'your-project-id',
  dataset: 'production',
  token: 'your-write-token',
  useCdn: false
});

// Read Sitecore XML
fs.readFile('sitecore-export.xml', (err, data) => {
  const parser = new xml2js.Parser();
  
  parser.parseString(data, (err, result) => {
    // Transform Sitecore structure to Sanity format
    const sanityDocuments = transformToSanity(result);
    
    // Upload to Sanity
    sanityDocuments.forEach(doc => {
      client.createOrReplace(doc);
    });
  });
});

function transformToSanity(sitecoreData) {
  // Map Sitecore fields to Sanity schema
  // Handle references and relationships
  // Convert rich text to Portable Text
  // Return array of Sanity documents
}

Pro tip: Start with a small subset of content (10-20 items) to refine your transformation scripts before migrating everything.

Verify Content Migration

After importing, verify that the content appears correctly:

  1. Check document counts in Sanity Studio match Sitecore counts
  2. Validate field mappings – titles, slugs, rich text, dates
  3. Verify references between documents (authors, categories, etc.)
  4. Test rich content rendering with Portable Text
  5. Confirm media assets are linked correctly
  6. Review localized content if multilingual

Use Sanity’s Vision plugin to run GROQ queries and inspect your dataset.

4.2 Migrate Media Assets

Media assets are crucial for user experience and SEO. Here’s how to migrate them from Sitecore to Sanity.

Export Media from Sitecore

Step 1: Navigate to Media Library in Sitecore

Step 2: Use Package Designer to export media items

Create packages for different media folders if your library is large.

Step 3: Download media packages

Store them in an organized folder structure.

Optimize Assets for Sanity

Before importing, optimize your assets:

Images:

Videos:

Documents:

Pro tip: Sanity automatically handles image optimization and CDN delivery. Your images will be served through Sanity’s CDN with on-the-fly transformations.

4.3 URL Mapping and SEO Preservation

Maintaining SEO equity during migration is crucial. Proper URL mapping ensures you don’t lose search rankings.

Create Comprehensive URL Map

Export all Sitecore URLs:

Use a crawler like Screaming Frog to export all current URLs:

Map to new Sanity-powered URLs:

Create a spreadsheet mapping old Sitecore URLs to new URLs:

Old Sitecore URLNew URLRedirect Type
/news/article-one/articles/article-one301
/about-us.aspx/about301
/media/file.pdf/assets/file.pdf301

4.4 Testing Your New Website

Thorough testing is critical before taking your new Sanity-powered website live. Here’s what you should test and how to do it effectively.
