A Drupal migration is a broad term, and it can mean a few different things depending on where you’re starting and where you’re headed. This guide covers what Drupal website migration actually involves, the risks worth planning around, and how LitExtension helps when your project involves moving data into or out of Drupal.
What Is Drupal Migration?
Drupal website migration generally falls into one of three categories:
- Migrating to Drupal from a different CMS: moving your content, structure, and functionality from another platform into Drupal to take advantage of its scalability and flexibility.
- Version-to-version migration within Drupal: upgrading an existing Drupal site to a newer major version, which involves more than a simple update since content, configuration, and modules all need to move across along with the core software.
- Migrating out of Drupal to a different CMS: moving away from Drupal toward a platform that better fits how your organization wants to manage content going forward, such as WordPress.
It’s worth drawing a line between simply copying content and a genuine data migration. Copying effort scales roughly in line with how much content you have; a proper migration is a more structured, one-time process that handles content, structure, metadata, and functionality together, so your new environment mirrors the old one where it should and improves on it where it can.
Why Organizations Consider a Drupal Migration
Drupal remains a genuinely capable CMS: it’s scalable, security-focused, and built around a flexible, modular architecture that suits organizations with complex content needs. That’s a strong case for migrating to Drupal if your current platform can’t keep up with your content model or security requirements.
On the other hand, organizations already running Drupal sometimes look to migrate away because the learning curve and ongoing development costs no longer match their team’s day-to-day needs, especially when routine content updates require developer involvement that a more content-editor-friendly CMS wouldn’t. And for anyone still running an older Drupal version that’s reached end of life, the loss of security updates and bug fixes is its own strong argument for either upgrading within Drupal or migrating to a different platform entirely.
DIY vs. Professional Drupal Migration
Whether to handle a Drupal migration in-house or bring in outside help usually comes down to complexity and available expertise:
- DIY migration can work if you have real technical expertise and time on your team, but it demands a deep understanding of Drupal’s architecture and tends to be time-consuming and error-prone if that expertise is thin.
- Professional or automated migration streamlines the process and meaningfully reduces the risk of data loss or errors, which matters more the larger and more complex your site is.
For a small site with straightforward content, DIY is often manageable. For anything involving significant content volume, custom modules, or integrations with other business systems, professional support tends to pay for itself.
What a Proper Drupal Migration Should Cover
A well-prepared migration starts well before any data actually moves. Here’s what’s worth doing upfront:
- Content audit: evaluate your existing content, identify what’s essential and what can be archived or dropped, and inventory your content types, fields, and taxonomies.
- Clean your data: remove duplicates and outdated information so you’re not migrating clutter along with everything else.
- Back up everything: a full backup of your database and files is non-negotiable before any migration begins.
- Inventory themes, modules, and custom code: understanding what’s currently in use helps assess compatibility with your target environment, whether that’s a newer Drupal version or an entirely different CMS.
- Map your integrations: every connected system, CRM, analytics, identity management, marketing automation, needs to be identified and accounted for before migration begins, not discovered mid-project.
- Plan for training: if your team is moving to an unfamiliar environment, budget time to get them comfortable with it once the migration is complete.
Common Risks and Challenges in a Drupal Migration
Knowing where migrations tend to go wrong is the best way to avoid it happening to yours:
- Content architecture drift: over time, Drupal sites accumulate fields, taxonomies, and content types added to solve one-off problems without much governance. These inconsistencies need to be resolved before migration tooling can process the content reliably.
- Integration continuity: a migration plan that doesn’t map every connected system before work begins tends to hit costly failures mid-project, right when they’re hardest to fix.
- Post-migration regression: performance, SEO, or functionality problems that only show up weeks after launch are some of the most damaging migration outcomes, since they’re harder to trace back to the migration itself.
- Architectural differences between Drupal versions: older Drupal versions differ enough from current ones that a straightforward upgrade isn’t always possible; a full rebuild is sometimes the more realistic path.
- Custom module and theme compatibility: code built for an older Drupal version, or for an entirely different CMS, usually needs real redevelopment work rather than a simple copy-over.
- Performance after launch: slow page loads or inefficient queries are common right after a migration; caching strategies and query optimization are usually needed to get performance back where it should be.
- Security: keeping core and modules current, configuring permissions correctly, and testing for vulnerabilities all matter just as much on the new environment as the old one.
How LitExtension Helps with Drupal Migration
LitExtension focuses on the data side of a Drupal migration: safely and accurately transferring your content, products, customers, and orders between Drupal and another platform, whether you’re moving data into Drupal or out of it. Here’s how the process works.
Step 1. Technical consultation with LitExtension experts
Your migration starts with a personalized consultation with our technical team. We review your source site’s structure, size, and any custom content types or modules in use, then define exactly what needs to move to your target platform. This lets us scope the project accurately and flag anything unusual before signing off on a clear plan together.
Step 2. Pre-migration setup and data mapping
Next, our team prepares both your source and target platforms for the transfer. We map your content, taxonomy, users, and media to the correct structure on the other side, so everything lands where it should. Custom fields or unusual content types get configured individually so nothing gets lost in the move.
Step 3. Run a demo migration
Before touching your full dataset, we run a demo migration using a sample of your content. This gives you an early look at how everything will appear on the new platform, and gives our team a chance to catch and fix any formatting or mapping issues before the full transfer runs.
Step 4. Perform the full migration
Once you approve the demo results, we move ahead with the complete data transfer. Your source site stays live and fully operational throughout the process, so there’s no downtime and no need to pause your site while the migration runs in the background.
Step 5. Migration results testing
After the full migration completes, our team runs a thorough QA review, checking content accuracy, formatting, internal links, media, and user accounts. We also verify SEO metadata and, if you’ve enabled the option, confirm 301 redirects are mapping your old URLs correctly, so search rankings carry over cleanly to your new site.
Step 6. Post-migration tasks
Since your source site keeps running during the migration, it may pick up new content or activity in the meantime. LitExtension’s post-migration services, including Recent Data Migration, Smart Update, and Re-migration, bring anything new over so your new site stays current once it goes live.
Step 7. Post-migration customer support
Our support doesn’t end when the migration does. For a set period after your Drupal migration completes, our team remains available to help with any questions, fix issues you spot, or guide you through your new setup.
What to Do After Your Drupal Migration
A migration is complete when the data lands, but a site is only actually ready once you’ve worked through a few more checks:
- Verify your content: review pages, posts, media, and any custom content types to confirm everything transferred accurately.
- Test functionality end to end: check forms, navigation, search, and any interactive elements across browsers and devices.
- Rebuild your SEO setup: confirm 301 redirects are working, submit a fresh sitemap to Google Search Console, and double-check titles, meta descriptions, and alt text carried over correctly.
- Optimize performance: set up caching, compress images, and address anything that’s noticeably slower than your previous site.
- Review security settings: confirm permissions, access controls, and SSL are configured correctly on the new environment.
- Train your team: if your team is working in an unfamiliar platform now, give them time to get comfortable with the new admin and publishing workflow.
- Monitor closely after launch: keep an eye on traffic, search rankings, and error logs for the first few weeks so you can catch and resolve anything that slipped through testing.
