Expert Custom Migrations Drupal 7 → 8/9/10

The key advantageWe handle the most complex Drupal migrations — the ones that standard tools cannot complete. When the usual migration breaks, loses content, mixes relationships, duplicates media, or simply cannot handle the data volume, we design a fully custom, safe, and reliable migration process.

These migrations require deep knowledge of Drupal 7 and 8/9/10 architecture, entity structure, fields, modules, and working with corrupted or non-standard data. We never use “blind” automatic imports: we design our own migration schema, create an intermediate data layer, and write project-specific migration modules.

This guarantees a successful transfer even in cases where other developers have given up.

When expert migration is required
   • Standard Drupal Migrate API throws errors
   • The site contains thousands of nodes, media, taxonomies, or users
   • Field Collection, custom fields, or custom modules are used
   • The database is damaged, duplicate data exists, relationships are broken
   • Data must be transformed, cleaned, or reconstructed
   • Complex structures must be migrated: Paragraphs, multilevel menus, entities
   • The site is outdated and full of patches and temporary solutions
   • Integrations depend on legacy data that must be preserved

How we work (key steps)
   1. Analyze Drupal 7 structure
Identify issues, damaged data, non-standard fields, custom modules.
   2. Create an intermediate data layer
In Drupal 7 we build an export module that extracts EVERYTHING cleanly and structurally.
   3. Prepare and normalize the data
Remove junk, restore lost relationships, clean and reorganize data.
   4. Develop custom migration modules for Drupal 8/9/10
Import content as if it originally belonged to the new version.
   5. Test and compare with the original
Validate counts, media, relations, and importer performance.
   6. Launch the final site on Drupal 9/10
With modern architecture, updated modules, and high performance.

What we migrate without loss
   • All content types
   • Paragraphs and complex nested structures
   • Media, images, documents
   • Taxonomies and hierarchical vocabularies
   • Menus, blocks, configuration
   • Users, roles, permissions
   • Settings and business logic
   • Custom table and custom module data

The key advantage

We migrate even those sites that:
❌ can’t be migrated with standard tools
❌ other developers failed to migrate
❌ contain huge volumes of content or corrupted structure
✔️ and we preserve absolutely everything

After migration, you get a fully working Drupal 9/10 website — fast, secure, modern, and ready to grow.

If you have a complex Drupal 7 website and were told it “cannot be migrated,” these are exactly the cases we specialize in.
