Stop Waiting: The Developer's Complete Guide to SiteVision to WordPress Migration Plus the Best 10 Agencies That Execute It Right in 2026

A SiteVision to WordPress Migration without a proper content node export, URL alias mapping, metadata transfer, widget-to-block conversion, and redirect validation is a post-launch incident waiting to happen. This post covers the full technical workflow and the agencies trusted to execute it correctly in 2026.

Why Developers Keep Getting Asked to Move Organizations Off SiteVision

SiteVision is a CMS specifically geared towards Swedish companies, the public sector, and large organizations seeking a secure, stable, and user-friendly platform. Established in 2002 and headquartered in Örebro, Sweden, it is one of the leading providers of CMS and intranet solutions in the Nordics, particularly amongst public institutions and mid-large corporate clients.

For organizations operating within the Swedish public sector or Nordic enterprise market, SiteVision made sense for years. It was purpose-built for that context, editor-friendly, and deeply integrated with Swedish digital workplace standards.

But the ceiling is real and organizations are hitting it.

Managing multiple languages, currencies, and market-specific content is technically complicated and costly in SiteVision. The platform is built for a Swedish context and lacks the built-in flexibility required for effective international expansion.

WordPress supports international growth through multisite functionality, language plugins, and WooCommerce.

Add to that the cost differential, the plugin ecosystem gap, the developer talent pool difference, and the SEO tooling advantage, and the migration decision becomes straightforward for most organizations.

What is not straightforward is the technical execution. SiteVision stores content in a proprietary node-based architecture with Java-driven page rendering, a portlet-based widget system, and URL structures that differ fundamentally from WordPress's permalink architecture. Getting the migration right requires understanding both systems at a code level.

This guide covers the technical workflow and the agencies that have built the process to handle it reliably.

The Architecture Gap: SiteVision vs WordPress

Before writing any migration code, you need a clear model of what you are bridging.

SiteVision Architecture:
├── Java-based application server (Jetty/OSGi)
├── Node-based content tree (hierarchical page nodes)
├── Portlet/Widget system (drag-and-drop modules)
├── Velocity templating (VTL for page rendering)
├── JCR (Java Content Repository) for content storage
├── Built-in versioning and workflow approval chains
├── Native intranet and social features
├── URL structure: /sv/page-name/ or /en/page-name/
└── RESTful API available for content export

WordPress Architecture:
├── PHP 8.x + MySQL / MariaDB
├── Post-based content model (wp_posts unified table)
├── Block editor (Gutenberg) / Classic editor
├── Theme system (PHP templates + template hierarchy)
├── Custom Post Types + ACF for structured content
├── Plugin ecosystem (59,000+ plugins)
├── Permalink structure: /page-slug/ (configurable)
└── REST API + WP-CLI for content import

The critical architectural difference: SiteVision's node tree stores content as typed portlet configurations within page nodes. Extracting that content into WordPress-compatible HTML or Gutenberg blocks requires parsing each portlet type and transforming its output, not just copying text fields from a database table.

Phase 1: Pre-Migration Audit

This phase prevents post-migration surprises. Agencies that skip it discover problems at week eight of a twelve-week project.

# Step 1: Full crawl of the live SiteVision site
screamingfrogseospider --crawl https://your-sitevision-site.com \
  --headless \
  --save-crawl \
  --export-tabs "Internal:All,Response Codes:All,Page Titles:All,Meta Description:All,H1:All,Canonical URL:All"

# Step 2: Export via SiteVision REST API
# SiteVision exposes a REST API for content export
# Endpoint: /rest/api/1/node/{nodeId}

curl -H "Accept: application/json" \
     -u username:password \
     "https://your-sitevision-site.com/rest/api/1/node/root?depth=999" \
     > sitevision_content_tree.json

# Step 3: Google Search Console baseline
# Export: Performance > Pages > Last 6 months
# Every URL with clicks needs a verified 301 post-migration

Map the full content tree before touching a single file. Every SiteVision page node becomes a WordPress page or post. Every URL in the SiteVision tree must have a corresponding WordPress URL and a 301 redirect configured before go-live.

Phase 2: Content Export and Transformation

SiteVision's REST API returns content as a hierarchical JSON structure. The migration script must walk that tree and transform each node type into a WordPress-compatible format.

// Node.js: SiteVision content tree to WordPress XML transformer

const axios = require('axios');
const xml2js = require('xml2js');

const SITEVISION_BASE = 'https://your-sitevision-site.com';
const WP_IMPORT_FILE = 'sitevision-migration.xml';

// SiteVision portlet type to WordPress block mapping
const PORTLET_TO_BLOCK = {
  'sv:textPortlet':     (node) => `<!-- wp:paragraph --><p>${node.text}</p><!-- /wp:paragraph -->`,
  'sv:imagePortlet':    (node) => `<!-- wp:image --><figure class="wp-block-image"><img src="${node.imageSrc}" alt="${node.alt || ''}"/></figure><!-- /wp:image -->`,
  'sv:videoPortlet':    (node) => `<!-- wp:embed {"url":"${node.videoUrl}"} /-->`,
  'sv:tablePortlet':    (node) => buildTableBlock(node),
  'sv:listPortlet':     (node) => buildListBlock(node),
  'sv:htmlPortlet':     (node) => `<!-- wp:html -->${node.html}<!-- /wp:html -->`,
  'sv:linkPortlet':     (node) => `<!-- wp:paragraph --><p><a href="${node.url}">${node.linkText}</a></p><!-- /wp:paragraph -->`,
};

async function fetchNodeTree(nodeId, depth = 0) {
  const response = await axios.get(
    `${SITEVISION_BASE}/rest/api/1/node/${nodeId}`,
    { auth: { username: process.env.SV_USER, password: process.env.SV_PASS } }
  );
  return response.data;
}

function transformNodeToWPPost(node) {
  // Concatenate all portlet content in page order
  const postContent = (node.portlets || [])
    .sort((a, b) => a.sortOrder - b.sortOrder)
    .map(portlet => {
      const transformer = PORTLET_TO_BLOCK[portlet.type];
      return transformer
        ? transformer(portlet)
        : `<!-- unsupported portlet: ${portlet.type} -->`;
    })
    .join('\n');

  return {
    post_title:   node.properties?.displayName || node.name,
    post_content: postContent,
    post_name:    slugify(node.properties?.displayName || node.name),
    post_status:  node.published ? 'publish' : 'draft',
    post_type:    node.depth === 0 ? 'page' : 'page',
    // SEO metadata from SiteVision page properties
    seo_title:    node.properties?.seTitle || '',
    seo_desc:     node.properties?.seDescription || '',
    canonical:    node.properties?.canonicalUrl || '',
  };
}

async function buildRedirectMap(nodeTree, baseUrl) {
  const redirects = [];
  function walkTree(node, parentPath = '') {
    const svPath = parentPath + '/' + (node.properties?.nameInPath || node.name);
    const wpSlug = '/' + slugify(node.properties?.displayName || node.name) + '/';
    if (svPath !== wpSlug) {
      redirects.push({ from: svPath, to: wpSlug });
    }
    (node.children || []).forEach(child => walkTree(child, svPath));
  }
  walkTree(nodeTree);
  return redirects;
}

Phase 3: WordPress Import via WP-CLI

Once content is transformed into WordPress XML format, WP-CLI handles the bulk import efficiently.

# Import content using WP-CLI
wp import sitevision-migration.xml --authors=create

# Verify import results
wp post list --post_type=page --fields=ID,post_title,post_status | head -50

# Check for import errors
wp import --info

# Update internal links from SiteVision URL patterns to WordPress permalinks
# Run find-replace on all post content
wp search-replace '/sv/' '/' --all-tables
wp search-replace '/en/' '/en/' --all-tables

# Regenerate slugs if needed
wp post list --post_type=page --fields=ID,post_title \
  | while read id title; do
    wp post update $id --post_name="$(echo "$title" | tr '[:upper:]' '[:lower:]' | sed 's/ /-/g')"
  done

Phase 4: SEO Metadata Migration

SiteVision stores SEO metadata as page node properties. Every title tag, meta description, and canonical URL must transfer to WordPress before go-live.

<?php
// PHP: Bulk insert SiteVision SEO metadata into WordPress
// using Yoast SEO post meta fields

function insertSiteVisionSEOMeta($wpPostId, $svPageData) {
    $seoFields = [
        '_yoast_wpseo_title'       => $svPageData['seTitle'] ?? '',
        '_yoast_wpseo_metadesc'    => $svPageData['seDescription'] ?? '',
        '_yoast_wpseo_canonical'   => $svPageData['canonicalUrl'] ?? '',
        '_yoast_wpseo_focuskw'     => $svPageData['keywords'] ?? '',
        '_yoast_wpseo_opengraph-title'       => $svPageData['ogTitle'] ?? '',
        '_yoast_wpseo_opengraph-description' => $svPageData['ogDescription'] ?? '',
    ];

    foreach ($seoFields as $metaKey => $metaValue) {
        if (!empty($metaValue)) {
            update_post_meta($wpPostId, $metaKey, sanitize_text_field($metaValue));
        }
    }
}

// Run as part of post-import processing
$pages = get_posts([
    'post_type'   => 'page',
    'numberposts' => -1,
    'post_status' => ['publish', 'draft'],
]);

foreach ($pages as $page) {
    $svData = getSiteVisionPageData($page->post_name); // Lookup from exported JSON
    if ($svData) {
        insertSiteVisionSEOMeta($page->ID, $svData);
    }
}

Phase 5: Redirect Configuration and Validation

Every SiteVision URL needs a correctly configured 301 redirect before the DNS cutover.

<?php
// Bulk redirect creation using Redirection plugin API
// SiteVision uses /sv/ prefix for Swedish and /en/ for English

$redirect_map = [
    '/sv/om-oss/'           => '/om-oss/',
    '/sv/tjanster/'         => '/tjanster/',
    '/en/about-us/'         => '/about-us/',
    '/en/services/'         => '/services/',
    // Generated from pre-migration Screaming Frog crawl and SiteVision node tree
];

foreach ($redirect_map as $from => $to) {
    $existing = Red_Item::get_for_url(ltrim($from, '/'));
    if (empty($existing)) {
        Red_Item::create([
            'url'         => $from,
            'action_data' => ['url' => $to],
            'action_type' => 'url',
            'action_code' => 301,
            'match_type'  => 'url',
            'group_id'    => 1,
        ]);
    }
}

# Validate all redirects against staging before production cutover
while IFS=',' read -r old_url new_url; do
  status=$(curl -s -o /dev/null -w "%{http_code}" \
    --max-redirs 0 "https://staging.your-wp-site.com${old_url}")
  destination=$(curl -s -o /dev/null -w "%{redirect_url}" \
    --max-redirs 0 "https://staging.your-wp-site.com${old_url}")

  if [ "$status" = "301" ]; then
    echo "OK: ${old_url} -> ${destination}"
  else
    echo "FAIL: ${old_url} returned ${status}"
  fi
done < sitevision_redirect_map.csv

Five Technical Mistakes That Break SiteVision to WordPress Migrations

These failure patterns appear in post-mortems consistently and are entirely preventable with the right process.

Unsupported portlet types left as HTML comments. SiteVision has more portlet types than most migration scripts account for. Any portlet type without a defined transformer in the migration script produces an unsupported comment in the post content rather than the actual rendered content. Run a full portlet type inventory before writing the migration script and confirm a handler exists for every type present in the content tree.

SiteVision language prefix not handled in redirect map. SiteVision uses language prefixes in URL paths such as /sv/ for Swedish and /en/ for English. WordPress permalink structures do not include these prefixes by default. Every redirect must strip or remap the language prefix correctly, and multilingual WordPress configurations using WPML or Polylang must be set up before redirect validation runs.

Node tree order not preserved in page hierarchy. SiteVision's page tree has explicit sort order on every node. WordPress page hierarchy is managed through parent page relationships and menu order. If the migration script does not preserve node sort order in the WordPress page structure, navigation menus and breadcrumb paths will be incorrect post-migration.

JCR binary assets not resolved before link update. SiteVision stores some media assets in the Java Content Repository with binary references. These must be exported as actual files and imported into WordPress media library before any content referencing them is finalized. Running content link updates before media migration creates broken references that require a second pass to fix.

No post-launch GSC monitoring window. The 30 days after go-live are where migration quality becomes visible through redirect hit data, crawl errors, and ranking changes. Agencies that close the engagement at launch leave this risk window unprotected. Minimum 30 days of GSC monitoring with redirect plugin logging active is the standard for a migration treated as a platform outcome operation.

Final Thoughts for Developers

A SiteVision to WordPress migration is technically more demanding than most CMS-to-WordPress moves because of the Java application server architecture, the portlet-based content model, and the JCR binary asset storage that sits underneath SiteVision's familiar editor interface.

The agencies on this list have built the tooling and process to handle those architectural specifics reliably. When evaluating which one fits your engagement, ask them specifically about their SiteVision portlet type handling, their language prefix redirect strategy, and their post-launch GSC monitoring protocol.

SiteVision to WordPress Migration done correctly delivers a WordPress platform that outperforms SiteVision on every metric that matters in 2026: development flexibility, plugin ecosystem depth, SEO tooling capability, and total cost of ownership.

10 Technical FAQs on SiteVision to WordPress Migration in 2026

1. What is SiteVision CMS and why is it primarily used in Sweden?
SiteVision is a CMS specifically geared towards Swedish companies, the public sector, and large organizations seeking a secure, stable, and user-friendly platform. It is optimized for intranets and public websites where usability and security are critical. Established in 2002 and headquartered in Örebro, Sweden, it is one of the leading providers of CMS and intranet solutions in the Nordics, particularly amongst public institutions and mid-large corporate clients. Its strong position in the Swedish public sector reflects deliberate product design for that market context rather than broad international adoption.

2. What is SiteVision's underlying architecture and why does it affect migration complexity?
SiteVision runs on a Java-based application server using an OSGi framework with Jetty as the web container. Content is stored in a Java Content Repository (JCR) as a hierarchical node tree, and pages are rendered through Velocity templating with portlets handling individual content modules. This architecture differs fundamentally from WordPress's PHP and MySQL model. The migration must transform JCR node content into WordPress post format, convert portlet configurations into HTML or Gutenberg blocks, resolve JCR binary file references into WordPress media library entries, and remap SiteVision's URL patterns to WordPress permalinks.

3. How does SiteVision's portlet system translate to WordPress?
SiteVision uses portlets as the primary content module type. Each portlet has a type (text, image, video, list, table, HTML, link, etc.) and configuration properties. In WordPress, the closest equivalents are Gutenberg blocks for modern builds or HTML content fields for classic editor builds. The migration script must map every SiteVision portlet type to a WordPress block or HTML equivalent, handling edge cases where portlet configuration data does not map directly to a simple HTML representation.

4. How are SiteVision language prefixes handled during migration to WordPress?
SiteVision uses URL path prefixes for language variants such as /sv/ for Swedish and /en/ for English. WordPress handles multilingual content through plugins including WPML, Polylang, or TranslatePress. The migration must either strip language prefixes for single-language WordPress builds with 301 redirects from all prefixed URLs, or configure the multilingual plugin to replicate the language structure before content migration begins so that pages are created in the correct language context and redirects route each language URL to its correct WordPress equivalent.

5. What is the SiteVision REST API and how is it used for content export?
SiteVision works as both a traditional CMS and a headless CMS, with future-proof flexibility built into the platform architecture. SiteVision exposes a REST API that returns content nodes as JSON, including page properties, portlet configurations, metadata, and file references. The API is the primary export mechanism for automated migrations, returning the full content tree from any given node down to configurable depth. Authentication is required and rate limits apply on some SiteVision installations. For very large sites, pagination must be handled in the export script to avoid timeout failures on deep tree exports.

6. How should media and file assets be handled in a SiteVision migration?
SiteVision stores uploaded files in the JCR file system under a managed path structure. During migration, every file referenced in content must be exported from the SiteVision file manager, copied to the WordPress uploads directory, and registered as a WordPress attachment with correct metadata. Content that references SiteVision file paths must be updated post-import to reference WordPress media library URLs. Files stored as binary JCR assets require UUID resolution before export, similar to how Contao handles binary file references.

7. What is the recommended WordPress plugin stack for a site migrated from SiteVision?
Yoast SEO or Rank Math for SEO metadata management replacing SiteVision's native SEO fields. The Redirection plugin for 301 redirect management and post-launch monitoring. WP Rocket or LiteSpeed Cache for performance caching. Wordfence or Sucuri for security. WPML or Polylang for multilingual sites. WPForms or Gravity Forms to replace SiteVision's native form builder. Advanced Custom Fields Pro for any structured content that exceeds standard WordPress post fields. The Metatag module equivalent in WordPress, typically Yoast's schema settings, handles structured data that SiteVision managed through its built-in SEO tools.

8. How long does a SiteVision to WordPress migration take?
For a standard organization website with 50 to 200 pages, a professional migration takes 4 to 8 weeks including pre-migration audit, portlet mapping, content transformation script development, media migration, redirect configuration, staging validation, and post-launch monitoring. Larger public sector sites with 500 plus pages, multiple language variants, complex portal features, and intranet components require 12 to 20 weeks. Any agency quoting this migration in under 2 weeks is compressing the staging validation and redirect mapping phases that protect SEO performance post-launch.

9. What are the most common post-migration SEO issues in SiteVision to WordPress moves?
The most common issues are missing or incorrectly configured 301 redirects for language-prefixed URLs, metadata not transferred from SiteVision page properties to WordPress Yoast or Rank Math fields, canonical tag configuration errors in multilingual builds, and XML sitemap generation not including all migrated pages. Each of these is detectable with a post-migration Screaming Frog crawl combined with Google Search Console monitoring in the first 30 days. Agencies that include a post-launch monitoring window specifically for these issues protect organic rankings through the transition period.
