Drupal migration services are the end-to-end process of moving a website or digital platform into Drupal (or between Drupal versions) while preserving business-critical functionality and content integrity.
A real migration is more than transferring pages:
-
It preserves data relationships (content types, taxonomy, authorship, translations, references).
-
It protects SEO equity (URLs, redirects, metadata, structured data, indexability).
-
It maintains governance and access (users & roles, permissions, editorial workflows).
-
It reduces operational risk (repeatable runs, validation, QA, rollbacks).
Migration vs. simple import: the practical difference
A basic import typically brings over flat content (like titles and body text). In contrast, Drupal content migration treats your site as a structured system:
-
Data mapping defines how each legacy element becomes a Drupal entity or field.
-
Content types and fields are rebuilt with future scalability in mind.
-
Taxonomy and references remain connected (categories, tags, related content, embedded assets).
-
Multilingual content is migrated correctly (languages, translations, language fallbacks).
-
SEO-safe Drupal migration ensures search engines don’t interpret the launch as a brand-new site.
Business value is straightforward: faster delivery, fewer regressions, more stable rankings, and a Drupal foundation that’s easier to evolve.
How Drupal Migration Works
A reliable Drupal website migration follows a structured lifecycle. The goal is repeatability: you should be able to migrate, verify, adjust, and migrate again until everything is correct.
1. Analysis & audit
We start by understanding what must be migrated and what should be retired:
-
Content inventory (pages, articles, products, landing pages, media)
-
Existing content types, fields, and taxonomy structures
-
Users & roles, editorial workflows, permissions model
-
Multilingual setup and translation completeness
-
SEO footprint (URL patterns, redirects, metadata, indexation state)
-
Integrations and dependencies (CRM, search, DAM, analytics, custom APIs)
-
Legacy systems and data sources (custom CMS, databases, third-party tools)
Deliverable: a migration scope with risks, assumptions, and priorities.
2. Data mapping (the migration blueprint)
Data mapping translates legacy content into Drupal’s structure:
-
Define target content types and field schemas
-
Map legacy fields to Drupal fields (including transformations and normalization)
-
Map taxonomy terms, vocabularies, and hierarchical relationships
-
Map authorship, users & roles, and content ownership
-
Identify edge cases: missing references, inconsistent formats, invalid HTML, outdated embeds
Deliverable: a mapping document and migration plan aligned with your Drupal architecture.
3. Migration execution (iterative runs)
Migration should not be “one big bang.” We run migrations in stages:
-
Start with a representative subset (pilot)
-
Validate results, fix mapping issues, rerun
-
Migrate remaining content in batches
-
Keep migrations idempotent (safe to rerun without duplications)
This approach reduces risk and makes QA meaningful, because you can compare outcomes between iterations.
4. Validation & QA
Quality assurance is where migrations succeed or fail. We validate:
-
Content completeness (counts, sampling, critical paths)
-
Field accuracy (formats, dates, references, media links)
-
Taxonomy correctness (terms, hierarchies, tagging consistency)
-
User access control (roles, permissions, editorial flows)
-
Multilingual content integrity (language association, translated fields)
-
SEO signals (URLs, metadata, canonical behavior, indexability)
-
Performance (page speed, caching behavior, search indexing)
Deliverable: QA report and punch list with acceptance criteria.
5. Launch (controlled go-live)
A migration launch should be a coordinated release:
-
Freeze windows and content delta plan (what changes after the last migration run)
-
DNS / hosting readiness, environment parity
-
Redirect deployment and verification
-
Monitoring: logs, analytics, search console signals, crawl health
-
Post-launch stabilization plan
Deliverable: launch checklist and a rollback-ready release plan.
What We Migrate
Drupal migration services typically cover far more than “pages.” A successful migration includes the full content model and the operational layer around it.
We migrate:
-
Content (pages, articles, products, landing pages)
-
Fields and structured data (custom fields, compound elements)
-
Taxonomies (categories, tags, vocabularies, hierarchies)
-
Media (images, documents, video references, alt text, captions)
-
Users & roles (accounts, permissions, authorship)
-
Multilingual content (translations, language metadata)
-
SEO data (URLs, metadata, canonical rules, schema where applicable)
If needed, we also handle:
-
Content references and entity relationships
-
Comments, revisions, moderation states
-
Menus and navigation structures
-
Redirect rules and legacy URL patterns
Drupal Version Upgrades
Drupal version upgrades are often the most demanding type of migration because Drupal has major architectural shifts between generations — especially from Drupal 6/7 to Drupal 10.
Drupal 6 / 7 → Drupal 10
A Drupal 7 to Drupal 10 migration is not a “standard upgrade.” It’s a platform transition that usually involves:
-
Rebuilding the content model with modern Drupal best practices
-
Replacing legacy approaches with supported patterns (entities, fields, configuration management)
-
Re-implementing functionality from older modules that are deprecated or no longer available
-
Updating theming to modern front-end approaches (Twig-based themes, component-driven UI)
Key challenges typically include:
-
Legacy data inconsistencies and “historical” content edge cases
-
Custom modules that must be rewritten
-
Outdated taxonomy structures that no longer fit business needs
-
Performance bottlenecks caused by old architecture and storage patterns
Drupal 8 → 9 / 10
Drupal 8 to Drupal 9/10 upgrades are often smoother, but still require careful planning:
-
Address deprecated APIs and dependencies
-
Update contributed modules and themes
-
Ensure compatibility with the target Drupal core
-
Validate performance, caching, and search behavior after the upgrade
Replacing deprecated modules without breaking the product
A safe approach is to treat module replacement as a functional requirement, not a checkbox:
-
Identify what the module actually provides (business function)
-
Choose a supported alternative or implement a custom solution
-
Confirm content storage changes and configuration implications
-
QA the user experience and editorial workflows
SEO-Safe Drupal Migration
SEO-safe Drupal migration protects organic traffic by ensuring search engines can interpret the new site as a stable continuation — not a different website.
URL preservation
If you can preserve URLs, you should. Stable URLs reduce reindexing risk and help maintain rankings.
We focus on:
-
Keeping URL patterns consistent where feasible
-
Preserving critical high-traffic URLs
-
Avoiding accidental changes caused by rewritten aliases or language prefixes
301 redirects (non-negotiable when URLs change)
When URL preservation isn’t possible, 301 redirects are required:
-
Map old URLs to the most relevant new destinations
-
Avoid chains (old → intermediate → new)
-
Avoid blanket redirects to the homepage (bad for UX and SEO)
-
Validate redirects at scale (spot checks are not enough)
Meta data and on-page signals
Migration must keep core SEO fields and signals aligned:
-
Title tags, meta descriptions
-
Canonical rules and duplicate handling
-
Open Graph / social metadata (when used)
-
Structured data (where applicable)
-
Robots directives and indexation controls
Indexing risks and traffic protection
The biggest SEO failures usually come from:
-
Accidentally blocking crawlers (robots.txt or meta robots misconfig)
-
Launching with missing redirects
-
Broken canonical rules causing duplicate indexing
-
Large-scale 404s and soft 404s
-
Missing internal links and navigation changes that reduce crawl depth
To protect traffic, we recommend:
-
Pre-launch crawl comparison (old vs. staging)
-
Post-launch monitoring of index coverage and crawl errors
-
Rapid iteration window after go-live (fixes in days, not weeks)
Complex & Enterprise Migrations
Enterprise Drupal migration often involves more than content. It may include multiple systems, custom data models, and integration-heavy architectures.
We support complex scenarios such as:
Large databases and content-heavy platforms
When data volume grows, migration strategy matters:
-
Batch processing and staged migrations
-
Performance tuning for import operations
-
Validation using counts, sampling, and “golden record” checks
-
Operational readiness for search indexing and caching layers
Custom entities and non-standard models
Enterprise sites frequently store data beyond standard nodes:
-
Custom entities, relationships, and domain models
-
External data sources (ERP, PIM, DAM)
-
Business rules that must be preserved during transformation
Integrations and dependencies
Migrations often touch:
-
CRM and marketing automation (forms, lead routing)
-
Search platforms (Solr, Elasticsearch-based solutions)
-
SSO and identity providers
-
Analytics and event tracking
-
API consumers and partner integrations
Headless / decoupled Drupal
For decoupled architectures, migration must align with API contracts:
-
Content modeling for API-first delivery
-
Consistent identifiers and references for frontend apps
-
Versioning and backward compatibility strategy
-
Validation through API responses, not only UI pages

When You Need Drupal Migration Services
Drupal migration services make sense when your current platform creates technical or business drag — or introduces risk you can’t ignore.
Common triggers:
-
Outdated Drupal version (Drupal 6/7) with increasing maintenance cost
-
Performance issues caused by legacy architecture, heavy modules, or inefficient content structures
-
Security risks from unsupported core versions or outdated dependencies
-
Business scaling needs: multilingual expansion, more content types, improved governance, enterprise integrations
-
Platform consolidation: moving from WordPress or a custom CMS into a unified Drupal ecosystem
-
Replatforming initiatives: redesign, rebranding, headless transition, or new editorial workflows
If you’re unsure whether you need a full migration or an upgrade path, an initial assessment typically clarifies scope, risk, and ROI quickly.
