Website migration: How to update your website without losing everything
Imagine that your team is managing your company's website on a system that feels increasingly outdated and cumbersome. Your current CMS operates at a frustratingly slow pace, with navigation that's unnecessarily complex, and a user experience that challenges even the most technically minded person. Content editors find themselves spending hours wrestling with basic updates that should take minutes, turning routine publishing tasks into time-consuming ordeals.
This scenario is all too common across businesses today.
If your team is wrestling with an outdated, clunky content management system, you're certainly not alone. Thousands of organisations find themselves in the same position, recognising the urgent need for a website upgrade whilst being genuinely concerned about losing years of carefully built organic search visibility in the process.
In reality, website migrations don't need to become overwhelming projects that compromise your organic search visibility. With proper strategic planning and execution, you can successfully modernise your digital presence whilst preserving existing SEO value.
This comprehensive guide will walk you through the essential elements of migrating your website safely and effectively. We'll examine the planning process, execution strategies, and critical steps required to protect your organic search performance. By the conclusion, your team will have a clear roadmap to transform your digital presence without compromising the search visibility you've worked diligently to establish.
What is a website migration?
Before we dive into the nitty-gritty, let's get our definitions straight. A website migration is essentially moving your website from one environment to another. Think of it like relocating your house, you're taking all your belongings (content, design, functionality) and setting them up in a new location (platform, domain, or hosting environment).
Website migrations can take several forms:
- Platform migration: Moving from one CMS to another (like WordPress to Umbraco)
- Domain migration: Changing your website's address
- Hosting migration: Switching to a new web hosting provider
- Protocol migration: Moving from HTTP to HTTPS
- Site restructure: Reorganising your site's architecture and URL structure
For most marketing teams dealing with outdated systems, platform migration is the most common scenario. You're likely looking to escape from legacy systems that make simple tasks unnecessarily complicated.
The challenge? Search engines like Google have spent years understanding your current website. They know where everything lives, how pages connect, and what content matters most. When you change everything overnight, it's like rearranging a library and expecting everyone to find their favourite books immediately.
Why website migrations make marketing managers break out in cold sweats
Website migrations can go spectacularly wrong. I've seen businesses lose invaluable organic traffic overnight because they didn't plan properly.
But on the flip side, when done correctly, migrations can actually improve your organic search performance. Clean code, faster loading times, and improved user experience all signal to search engines and conversational AI tools that your site deserves better rankings and visibility.
The key is understanding that this isn't just a technical exercise. It's a strategic business decision that requires careful planning, meticulous execution, and ongoing monitoring.
The pre-migration planning phase: Your success foundation
Conducting a comprehensive site audit
Before you even think about touching your current website, you need to understand exactly what you're working with. This is like taking inventory before moving house, you need to know what you have, what's worth keeping, and what can be left behind.
Start by crawling your entire website using tools like Screaming Frog. Document everything:
- Total number of pages and posts
- URL structure and hierarchy
- Internal linking patterns
- Meta titles and descriptions
- Heading tags (H1, H2, H3, etc.)
- Images and alt text
- Redirect chains
- Broken links and 404 errors
Top performing content deserves special attention. Use Google Analytics and Search Console to identify your highest-traffic pages, top-converting content, and most valuable keyword rankings. These are your crown jewels, lose them, and you'll feel the pain for months.
Setting clear migration goals
What exactly are you trying to achieve with this migration? Better site speed? Improved mobile experience? Enhanced security? More flexible content management?
Write down your specific objectives and make them measurable. Instead of "improve user experience," aim for "reduce page load time by 40% and increase mobile usability score to 90+."
This clarity will guide every decision throughout the migration process and help you measure success afterwards.
Choosing the right migration partner
Unless you're a technical wizard with spare time on your hands, you'll need professional help. Choose your migration partner carefully. This isn't the time to go with the cheapest quote or your mate's cousin who "knows websites."
Look for agencies or developers with:
- Proven migration experience in your industry
- Case studies showing successful organic search preservation
- Clear communication and project management processes
- Post-migration support offerings
How to protect organic search visibility during website migrations
This is the million-dollar question that keeps marketing managers up at night. The good news? With proper planning and execution, you can maintain (and often improve) your search visibility during a migration.
Implementing a bulletproof redirect strategy
301 redirects are your best friend during a migration. These permanent redirects tell search engines "this page has moved permanently to a new location" and transfer most of the SEO value from the old URL to the new one.
Here's your redirect action plan:
- Map every single URL: Create a comprehensive spreadsheet showing old URLs and their new destinations
- Prioritise high-value pages: Focus first on your top-performing content and conversion pages
- Implement redirects before launch: Test them thoroughly in a staging environment
- Monitor redirect chains: Avoid multiple hops that slow down your site
- Update internal links: Don't rely solely on redirects for internal navigation
Preserving your site architecture
Search engines understand your website through its structure and internal linking. Dramatic changes can confuse crawlers and hurt your rankings.
Where possible, maintain similar:
- URL structures and naming conventions
- Navigation hierarchy and categories
- Internal linking patterns
- Content organisation
If changes are necessary, implement them gradually rather than all at once.
Content quality and optimisation
Migration is the perfect opportunity to audit and improve your content quality. Remove thin, duplicate, or outdated content that's dragging down your site's overall quality score.
For content you're keeping:
- Ensure meta titles and descriptions are preserved or improved
- Maintain heading tag hierarchy
- Keep image alt text and optimisation
- Preserve or enhance internal linking
- Update outdated information and statistics

Common migration mistakes that cost rankings
The "set and forget" redirect trap
Many teams implement redirects and assume they're permanent fixtures. Wrong! Redirects should be temporary solutions while you update internal links and external references.
After 6-12 months, you should have updated most internal links to point directly to new URLs, reducing reliance on redirects and improving site speed.
Ignoring mobile-first indexing
Google predominantly uses mobile versions of websites for indexing and ranking. If your new site isn't mobile-optimised or has mobile-specific issues, your rankings will suffer.
Test your new site thoroughly on mobile devices and use Google's Mobile-Friendly Test tool to identify problems before launch.
Forgetting about page speed
A shiny new website that loads slower than your old one is a step backwards. Google considers page speed a ranking factor, and users abandon slow sites faster than you can say "bounce rate."
Optimise images, minimise code, leverage browser caching, and choose quality hosting to ensure your new site flies.
Neglecting user experience signals
Google's Core Web Vitals measure real user experience on your website. Poor scores can hurt rankings, regardless of how technically perfect your migration appears.
Focus on:
- Largest Contentful Paint (LCP): How quickly main content loads
- First Input Delay (FID): How responsive your site feels to user interactions
- Cumulative Layout Shift (CLS): How visually stable your pages are
When things go wrong: Damage control strategies
Despite best efforts, sometimes migrations don't go perfectly. Don't panic, most issues can be fixed if you act quickly.
Traffic drops
If you notice significant traffic drops within the first week:
- Check redirects immediately: Ensure all high-traffic pages are properly redirected
- Review Search Console: Look for crawl errors or indexing issues
- Verify tracking codes: Make sure analytics are capturing data correctly
- Test site functionality: Ensure all forms and features work properly
- Submit sitemap again: Help search engines find your new content faster
Ranking fluctuations
Some ranking movement is normal during migrations. However, if you see dramatic drops:
- Identify affected pages: Use rank tracking tools to pinpoint problem areas
- Check technical issues: Ensure proper redirects and no server errors
- Review content changes: Make sure important content wasn't accidentally removed
- Monitor competitor activity: Sometimes external factors affect rankings
- Be patient: Rankings often recover within 2-4 weeks if everything else is correct
The migration timeline: What to expect
| Phase | Duration | Key activities |
|---|---|---|
| Planning & audit | 2-4 weeks | Site analysis, goal setting, partner selection |
| Development | 4-8 weeks | Building new site, testing functionality |
| Pre-launch | 1-2 weeks | Final testing, redirect setup, stakeholder preparation |
| Launch | 1-3 days | Go-live process, immediate monitoring |
| Stabilisation | 2-4 weeks | Issue resolution, performance optimisation |
| Evaluation | 4-6 weeks | Results analysis, further improvements |
Measuring migration success
You'll know your migration was successful when you see:
- Maintained or improved organic traffic within 4-6 weeks
- Better page load speeds and user experience metrics
- Increased conversion rates from improved functionality
- Positive user feedback about site usability
- Improved search console health scores
- Enhanced mobile performance and Core Web Vitals
Track these metrics before, during, and after your migration to measure success objectively.
Advanced migration considerations

- Local hosting considerations
- Cultural and linguistic content adaptation
E-commerce migrations
Online retailers face additional challenges:
- Product URL preservation
- Category structure maintenance

- Local search optimisation: Google My Business and local citations
- Cultural content adaptation: Australian spelling, terms, and references
- Seasonal considerations: Avoiding migrations during peak trading periods
Future-proofing your website
Once your migration is complete, don't rest on your laurels. Technology evolves rapidly, and your new website should be built to adapt:
- Choose flexible, scalable platforms
- Implement regular backup and security protocols
- Plan for ongoing content and SEO optimisation
- Monitor performance metrics consistently
- Stay informed about search engine algorithm updates
Conclusion: Your migration success story awaits
Website migrations don't have to be the stuff of nightmares. With proper planning, careful execution, and ongoing monitoring, you can successfully modernise your digital presence while preserving (and often improving) your organic search visibility.
Remember, this isn't just about moving from Point A to Point B, it's about positioning your business for future growth. A well-executed migration can deliver faster loading times, better user experiences, improved conversion rates, and enhanced organic search performance.
The key is treating migration as a strategic project, not just a technical task. Invest in proper planning, choose experienced partners, and maintain realistic expectations about timelines and results.
