- Drupal Migration & Upgrade

Seamless Drupal upgrades from Drupal 7/8/9 to Drupal 10/11 with zero data loss, full SEO continuity, and expert migration planning.
Sijzi Technologies delivers end-to-end Drupal migration and upgrade services — from Drupal 7, Drupal 8, and Drupal 9 to the latest Drupal 10 and Drupal 11. Whether you're running an end-of-life version or simply need to leverage the latest security patches and performance improvements, we handle the entire process with minimal downtime and zero content loss.
Our Drupal upgrade specialists audit your existing site structure, custom modules, contrib modules, themes, content types, and data relationships before writing a single line of code. We map every piece of content to its new destination, build custom migration plugins where needed, and validate every URL, redirect, and editorial workflow before go-live.
We cover complete site migrations, multi-site upgrades, headless Drupal decoupled migrations, and complex content migrations involving thousands of nodes, taxonomy terms, media assets, and user accounts — all with your SEO rankings, URL structure, and site performance intact.
Complete upgrade path from end-of-life Drupal 7 to Drupal 10 or 11, preserving all nodes, users, taxonomy, and media assets with zero data loss.
In-place major version upgrades with full module compatibility checks, deprecated API resolution, and theme updates for a smooth transition.
Bespoke Drupal migration plugins for complex content structures, legacy data formats, third-party CMS imports, and non-standard database schemas.
Migration of complex Drupal multisite installations and decoupled/headless setups (Next.js, Gatsby, React front-ends) to modern Drupal 10 architecture.
Structured migration of content types, paragraphs, fields, blocks, menus, taxonomy, views, users, and rich media files with full data integrity checks.
Comprehensive 301 redirect mapping, canonical URL setup, sitemap regeneration, and Google Search Console revalidation to maintain search rankings post-migration.
Full audit of contrib and custom modules for Drupal 10/11 compatibility, replacement of unsupported modules with modern alternatives, and security hardening.
Rebuilding or upgrading Drupal themes from legacy Bartik/Bootstrap 3 to Olivero, Claro, or custom Drupal 10 themes with modern CSS, Twig 2, and component-based design.
Post-migration optimization including caching configuration (Redis, Memcache, Varnish), CDN integration, security module setup, and Core Web Vitals improvements.
Hands-on editorial training for content teams, ongoing support packages, monitoring, and documentation tailored to your new Drupal 10/11 environment.
We audit your existing Drupal site — reviewing content types, fields, modules, themes, custom code, database size, user roles, and integrations to map out the full migration scope.
We define the upgrade path, choose migration strategies (in-place upgrade vs. fresh install with content import), set timelines, risk management plans, and assign milestones.
We configure a local and staging environment (DDEV, Lando, or Docker) mirroring production, install Drupal 10/11, and set up Composer-based project scaffolding.
We run and refine migration scripts, importing all nodes, taxonomy terms, users, files, blocks, and custom entities. We validate every record against the source database.
Contrib modules are updated or replaced with Drupal 10/11 compatible versions. Custom modules are refactored to remove deprecated APIs. Themes are rebuilt with Twig 2 compatibility.
Thorough testing covering content accuracy, URL redirects, form submissions, editorial workflows, search functionality, performance benchmarks, and cross-browser rendering.
We manage DNS cutover, server provisioning, SSL certificates, CDN setup, and go-live checklist execution. Post-launch, we monitor and provide a 30-day support window.
Tell us about your idea. Our engineers, designers and AI strategists will map a clear path from concept to launch — usually within a single discovery call.
