Why organizations migrate to Drupal
Enterprise scalability comes without licensing fees. Drupal handles multilingual, multi-site, and high-traffic architectures that proprietary CMSs charge premium license tiers for, making the economics compelling at scale.
Security and compliance are built in. Structured permissions, granular access control, GDPR-aligned audit trails, and a mature security team releasing patches within hours of a CVE reduce the risk surface that typically accompanies proprietary platforms.
Data sovereignty and vendor independence are core to the open-source model. Your data stays on infrastructure you control, in jurisdictions you choose, with no SaaS provider imposing data residency or retention policies.
- Total cost reduction: organizations migrating from Sitecore, Adobe Experience Manager, or SharePoint eliminate five- and six-figure annual licensing costs while gaining a more capable platform.
- Future-proof architecture: open standards, API-first capabilities, and a global contributor community mean Drupal keeps pace with headless, AI-assisted, and composable digital strategies.
- Proven at scale: Metadrop has migrated platforms for clients including Saint-Gobain, Save the Children, Solvay, and Syensqo across 50+ countries and 30+ languages.
Platforms we migrate from
- WordPress to Drupal: structured content migration using the Drupal Migrate API; all posts, media, taxonomy, users, and URL aliases migrated with redirect maps preserved.
- Sitecore to Drupal: content schema mapping, component library translation, and integration re-architecture for CRM-connected enterprise sites.
- Liferay to Drupal: portal content and intranet structures migrated preserving role-based access controls and workflow configurations.
- SharePoint to Drupal: document libraries, page content, and user directories migrated; editorial workflows and approval processes rebuilt as Drupal Workflows.
- Adobe Experience Manager (AEM) to Drupal: dam asset transfer, page hierarchy migration, and personalization rule mapping.
- Joomla, HubSpot, and custom-built platforms: source-agnostic extraction using ETL pipelines and custom Migrate API source plugins for non-standard data structures.
- Drupal version migrations (D6/D7 to D10/D11): handled as a distinct Drupal upgrade service; see that page if your source is already Drupal.
How Drupal migration works: our 5-phase process
Discovery and strategic decisions
Every migration is an opportunity to carry forward what works, retire what does not, and upgrade capabilities. Metadrop works with your team to decide jointly what content migrates, what is archived, and which features are rebuilt using contrib modules or custom code. These decisions are locked in Phase 1 so scope changes in later phases are minimized.
- Full content inventory: page count, content types, media assets, taxonomy structures, user accounts, and third-party data sources catalogued; each item tagged migrate / archive / rebuild.
- Source schema analysis: field-by-field mapping from source CMS to target Drupal content model; transformation rules and data gaps identified before any code is written.
- Risk assessment: integrations, redirects, SEO signals, and compliance requirements reviewed; timeline and effort estimate delivered as a written migration plan.
Migration architecture and staging
- Migrate API plugin development: custom source, process, and destination plugins written for your specific data shapes; no off-the-shelf assumptions.
- Destination content model setup: Drupal content types, fields, paragraphs, taxonomies, media types, and views configured to match the agreed information architecture.
- Staging environment runs: iterative migration runs on a staging copy of the source data; output validated against acceptance criteria before production is touched.
QA and pre-production validation
- Content completeness checks: every migrated record verified against the source. Counts, field values, metadata, media references, and taxonomy assignments are confirmed using the content_first and entity_mesh modules to query Drupal data integrity at entity level.
- Redirect and SEO validation: 301 redirect maps crawled with Screaming Frog; broken links, redirect chains, missing canonical tags, and absent hreflang entries flagged and resolved before the production run.
- Metadata integrity: metatags, OG tags, page titles, structured data, and XML sitemap entries validated against source; any gap treated as a blocker.
- Acceptance sign-off: stakeholder review of QA report; no production migration proceeds until all blockers are cleared.
Production migration and go-live
- Zero-downtime execution: production migration is scheduled and scripted; rollback procedures are in place before the cutover window opens.
- Content integrity validation: automated counts and spot-checks confirm every record, media asset, and URL alias migrated correctly; diff reports provided.
- Redirect deployment: 301 redirect maps activated to preserve SEO equity and prevent broken links for users and search engines.
Post-migration stabilization
- Smoke tests and regression checks run against all critical user journeys in the first 24 hours.
- Integration verification: SSO, CRM, analytics, payment, and search integrations confirmed end-to-end.
- Handover and editorial training for content teams on the new Drupal editorial interface.
What we preserve: content fidelity and zero data loss
Every selected content record transfers intact. Pages, articles, media, documents, taxonomy terms, user accounts, and structured field data are all accounted for in the migration run, not approximated.
- URL structure and SEO equity: all source URLs mapped; 301 redirects deployed; hreflang, canonical tags, metatags, XML sitemaps, and structured data rebuilt or transferred.
- Third-party integrations: Salesforce, HubSpot, SAP, ERP middleware, Solr/Elasticsearch, SSO (SAML, OAuth, OpenID Connect), and analytics tags tested end-to-end before release.
- Editorial workflows and permissions: content approval processes, role-based access, and publishing workflows rebuilt as Drupal Workflows and permission sets.
- Media library and digital assets: images, documents, and video embeds migrated with correct file paths and metadata; CDN configurations updated.

Frequently asked questions about Drupal migration
What is a Drupal migration and how does it work?
A Drupal migration is the process of moving content, users, media, and configuration from a source CMS or custom platform into a new Drupal installation. Metadrop uses the Drupal Migrate API (Drupal's native ETL framework) to extract data from the source, transform it to match the target content model, and load it into Drupal with full integrity checks at each stage.
How long does a Drupal migration take?
Timeline depends on content volume, source platform complexity, number of integrations, and whether a new Drupal information architecture is designed alongside the migration. Small migrations (under 5,000 records, no custom integrations) typically complete in 4 to 6 weeks. Complex enterprise migrations with large media libraries, multiple integrations, and multilingual content typically run 10 to 20 weeks. A written timeline estimate is provided after the discovery phase.Will I lose content or SEO rankings during the migration?
Provided the migration is planned correctly, the answer is no. Metadrop validates every content record against the source before and after migration, deploys 301 redirect maps for all changed URLs, and preserves metatags, canonicals, and structured data. SEO monitoring is in place before, during, and after the cutover.How much does a Drupal migration cost?
Cost depends on the source platform, content volume, the number of custom integrations, and whether new design and content architecture work is included. Fixed prices are not published because no two migrations are alike. Request a free assessment, and we will return a scoped estimate within 5 business days.What happens to our third-party integrations during migration?
Integrations are inventoried in the discovery phase and rebuilt or reconnected on the Drupal side before go-live. Common integrations handled include Salesforce CRM, HubSpot, SAP, Solr/Elasticsearch, SAML and OAuth SSO, Google Analytics/Tag Manager, and payment gateways. No integration goes live without passing end-to-end testing in staging.
Can you migrate a multilingual site?
Yes. Metadrop has migrated sites in 30+ languages. The Drupal Migrate API supports language-specific content mappings, and Drupal's multilingual stack (Language, Content Translation, Configuration Translation modules) preserves all language variants, hreflang tags, and per-language URL aliases.
Do you migrate from older Drupal versions (D6, D7) to Drupal 11?
Drupal 6 and Drupal 7 upgrades are treated as a distinct service. See our Drupal upgrade services page for EOL upgrade paths. If your source is an external CMS (WordPress, Sitecore, etc.) and your destination is Drupal 11, that falls under this migration service.
