Let’s get started

Experienced migration partner

Alliance Interactive has spent more than twenty years moving organizations onto the CMS platforms that fit how they actually work. We have taken legacy Drupal 7 sites to Drupal 11, moved WordPress installs off page builders that had quietly become unmanageable, rebuilt Shopify storefronts without dropping a single order record, and given Wix and Squarespace teams a real content management system for the first time.

Migration services we offer

A migration is only as strong as the plan behind it. We start with a full audit of what you have today, including content types, custom fields, integrations, and redirects, then map every piece to its new home before a single record moves. The platform matters less than the discipline of the process.

Discovery and Migration Strategy

Before we touch a database, we inventory your content model, third-party integrations, traffic patterns, and technical debt. This audit becomes the migration roadmap: what moves as-is, what gets rebuilt, and what gets retired. Marketing gets a clear picture of what the new site will do differently. IT gets a plan for hosting, security, and rollback.

WordPress Migration

Sites built on WordPress often accumulate years of plugin sprawl and page-builder shortcuts that slow every future update. We migrate content, media, and custom post types into a clean WordPress build, or move you off WordPress entirely if your content needs have outgrown it, without breaking the editorial workflows your team already relies on.

Content, Media and Database Migration

Posts, pages, custom post types, ACF fields, media libraries, and user accounts move with their relationships intact, not just their raw text. We validate the migrated database against the original before anything goes live, so nothing quietly drops during the move.

Drupal Migration and Upgrades

Whether you are consolidating a multisite Drupal 7 environment onto Drupal 11 or moving off another CMS onto Drupal for the first time, we use Drupal’s Migrate API to map content types, taxonomies, and user roles with precision. This is where Drupal’s structured content model earns its reputation, and where a rushed migration does the most damage if the mapping is wrong.

Shopify Migration

Commerce migrations carry a different kind of risk: product catalogs, customer records, order history, and payment continuity all have to survive the move intact. We migrate product data, apps, and checkout customizations into Shopify, rebuild themes in Liquid where needed, and validate every transaction path before launch so nothing interrupts revenue.

Wix and Squarespace Migration

Closed platforms like Wix and Squarespace make it difficult to export content on your own terms. We extract every page, image, and metadata field these platforms will allow, then rebuild the site on WordPress or Drupal so your team finally has real control over structure, permissions, and future development, instead of working inside a template.

Content, SEO and URL Architecture

Search rankings live or die on this step. We map every existing URL to its new destination, implement 301 redirects at scale, and preserve metadata, structured data, and sitemap integrity, so your organic traffic survives the move instead of resetting to zero.

End-to-end migration capabilities

Content and Database Migration

We migrate structured and unstructured content, media libraries, and user accounts between platforms while preserving relationships between records, not just the raw text.

URL Mapping and 301 Redirect Strategy

Every legacy URL is mapped to its new address and validated against your redirect rules, protecting the search equity you have already earned.

Theme and Template Rebuilds

Design and front-end templates are rebuilt natively on the destination platform rather than force-fit into a foreign theme engine, so performance and maintainability hold up over time.

Custom Module, Plugin and App Porting

Where a feature depends on a platform-specific module, plugin, or app, we assess whether it can be replicated natively or needs custom development on the new platform.

Third-Party Integrations

CRM, ERP, marketing automation, and analytics connections are re-established and tested individually, so no lead, order, or data sync silently breaks on launch day.

E-Commerce Data and Payment Continuity

Product variants, customer records, order history, and payment gateway configurations move with full fidelity, with PCI-DSS considerations addressed before go-live.

Multisite and Multilingual Migrations

Organizations running multiple properties or language variants get a migration plan that keeps shared components consistent while respecting site-specific content and permissions.

Post-Launch QA and Monitoring

After cutover, we run structured QA against the original site, monitor crawl errors and indexing in Search Console, and tune performance based on real traffic.

Who we move

Our migration work spans nonprofits, associations, higher education institutions, faith-based organizations, and defense and aerospace-adjacent firms, many of them running content-heavy sites with compliance requirements that a generic migration checklist does not account for. We plan for that from the start rather than discovering it mid-project.

Partner with an agency dedicated exclusively to websites

Websites are our sole focus, so our migration methodology is refined continually against real projects rather than theory. Our team brings platform-specific expertise across WordPress, Drupal, Shopify, and Wix, and stays with you past launch.

Frequently Asked Questions

Can you migrate between any combination of platforms?

Yes. We regularly move sites from WordPress to Drupal, Drupal to WordPress, Shopify to a headless commerce build, and Wix or Squarespace onto open-source platforms with far more flexibility. The direction matters less than the quality of the content audit that precedes it.

Will there be downtime during the migration?

Most migrations run in a parallel environment while your current site stays live. Content is synced and validated repeatedly before cutover, so the final switch happens during a brief, planned window, typically measured in minutes rather than hours.

Will our search rankings survive the move?

That is the point of the URL mapping and redirect work. Every existing page gets a mapped destination, structured data and metadata are preserved, and we monitor Search Console closely in the weeks after launch to catch anything that needs adjustment.

Can you migrate custom integrations, like our CRM or marketing automation platform?

Yes. We re-establish and individually test every integration, whether that is Salesforce, HubSpot, a membership database, or a payment gateway, so nothing silently breaks after the new site goes live.

How long does a typical migration take?

Timelines depend on content volume, integration complexity, and how much of the front end is being rebuilt versus ported as-is. A straightforward WordPress-to-WordPress migration might take a few weeks. A Drupal multisite consolidation with custom integrations runs longer. We scope this precisely during discovery rather than guessing upfront.

Do you handle e-commerce migrations, including order history and payment data?

Yes, for Shopify and other commerce platforms we migrate product catalogs, customer records, and order history with full fidelity, and validate payment gateway configurations before launch so revenue is never interrupted.

What happens to our custom plugins or modules during migration?

We assess each one individually. Some features have a native equivalent on the destination platform. Others need to be rebuilt as custom functionality. Either way, you get a clear answer during discovery, not a surprise during development.

Why would we move off Wix or Squarespace?

Those platforms are built for simplicity, not flexibility. Once your content needs, integration requirements, or editorial workflows outgrow what a closed page builder can offer, moving to WordPress or Drupal gives your team real ownership over structure, permissions, and future development.

How do we know if we need a migration partner instead of handling it internally?

If your internal team is confident in the platform you are moving to but stretched thin on execution bandwidth, or if the migration involves complex integrations, compliance requirements, or a content model more intricate than a simple export and import, an experienced partner reduces risk and protects your timeline.
