Website Migration Checklist (2026): The Complete Step-by-Step Guide

Migrating a website is one of the most important technical tasks a website owner can perform. Whether you’re moving to a faster hosting provider, upgrading to a VPS, changing your domain name, or switching content management systems (CMS), a successful migration requires careful planning.
Without a proper migration strategy, you could experience:
- Website downtime
- Lost search engine rankings
- Broken pages
- Missing images
- Database errors
- Email interruptions
- Poor user experience
- Revenue loss
Fortunately, most migration issues can be prevented with a well-planned checklist.
This comprehensive guide walks you through every stage of a website migration—from preparation and backups to SEO preservation and post-launch testing—helping you move your website with confidence while protecting your traffic and search rankings.
What Is Website Migration?
Website migration is the process of moving a website from one environment to another while maintaining its functionality, content, performance, and search engine visibility.
A migration may involve changing:
- Web hosting provider
- Domain name
- Server infrastructure
- Content Management System (CMS)
- Website architecture
- HTTPS configuration
- DNS provider
- File structure
The primary goal is to complete the transition without negatively affecting visitors or search engine rankings.
A successful migration should be almost invisible to your users.
Different Types of Website Migrations
Not every migration is the same. Understanding which type of migration you’re performing helps determine the steps you’ll need to follow.
Hosting Migration
This involves moving your website from one hosting provider to another.
Common examples include:
- Shared Hosting → Shared Hosting
- Shared Hosting → VPS
- VPS → Cloud Hosting
- Cloud → Dedicated Server
Hosting migrations are often performed to improve:
- Website speed
- Reliability
- Security
- Customer support
- Scalability
Domain Migration
Changing your domain requires additional SEO considerations.
Example:
oldwebsite.com
↓
newwebsite.comEvery page should have a permanent (301) redirect to preserve rankings and backlinks.
CMS Migration
Some businesses move from one content management system to another.
Examples include:
- HTML → WordPress
- Joomla → WordPress
- Drupal → WordPress
- Wix → WordPress
- Squarespace → WordPress
CMS migrations usually require URL mapping, redirect planning, and content verification.
Server Migration
Sometimes only the infrastructure changes.
For example:
- Apache → LiteSpeed
- Apache → NGINX
- Local server → Cloud VPS
Although visitors may not notice the change, server migrations can significantly improve loading speed and stability.
Why Website Migrations Fail
Website migrations often fail because they are rushed or poorly planned.
Some of the most common causes include:
No Backup
Many website owners begin a migration without creating a full backup.
If something goes wrong, recovery becomes difficult—or impossible.
Always create multiple backups before making any changes.
DNS Misconfiguration
Incorrect DNS settings can make your website temporarily unavailable.
Common mistakes include:
- Incorrect nameservers
- Wrong A records
- Missing AAAA records
- Missing MX records
Planning DNS changes in advance helps reduce downtime.
Missing Redirects
Changing URLs without implementing proper redirects causes:
- 404 errors
- Lost backlinks
- Ranking drops
- Poor user experience
Every old URL should redirect to its new equivalent whenever possible.
Incomplete File Transfer
Some migrations overlook:
- Uploads
- Images
- Themes
- Plugins
- Configuration files
Missing files can lead to broken layouts, missing media, and application errors.
Database Issues
Database migrations may fail because of:
- Character encoding mismatches
- Incorrect credentials
- Corrupted exports
- Missing tables
Always verify that the imported database matches the original.
Pre-Migration Checklist
Preparation is the foundation of a successful migration. Completing the following tasks before moving your website can save hours of troubleshooting later.
Audit Your Current Website
Before migrating, document the current state of your website.
Record:
- Total number of pages
- Blog posts
- Categories
- Media files
- Forms
- User accounts
- Installed plugins
- Themes
- Custom code
- Cron jobs
This creates a baseline for comparison after the migration.
Crawl Your Website
Use a website crawler to create a complete inventory of your pages.
Record:
- URLs
- Page titles
- Meta descriptions
- Canonical tags
- Heading structure
- Image alt text
- Internal links
This data helps ensure nothing is lost during the migration.
Create Multiple Backups
Never rely on a single backup.
Create backups for:
- Website files
- Database
- Emails (if hosted on the same server)
- Configuration files
- SSL certificates
Store copies in separate locations, such as cloud storage and a local computer.
Reduce DNS TTL
Several hours before migrating, reduce your DNS Time to Live (TTL) value. Learn more about how DNS propagation works in Cloudflare’s DNS Learning Center.
A lower TTL allows DNS changes to propagate more quickly once you point your domain to the new server, reducing the time visitors may reach the old hosting environment.
Verify Your New Hosting Environment
Before uploading anything, confirm that your new hosting account meets your website’s technical requirements.
Check:
- PHP version
- Database version
- Available storage
- Memory limits
- SSL support
- Required extensions (e.g., cURL, GD, Imagick)
- Backup options
- Firewall and security settings
Ensuring compatibility before migration minimizes unexpected errors.
Benchmark Your Current Website
Measure your website’s performance before moving it. Test your website using VeerHost Website Speed Test before and after the migration.
Record key metrics such as:
- Page load time
- Time to First Byte (TTFB)
- Largest Contentful Paint (LCP)
- Core Web Vitals
- Uptime
- Server response time
After the migration, compare these metrics to confirm the new hosting environment delivers the expected improvements.
Inventory Your DNS Records
Export or document all existing DNS records, including:
- A records
- AAAA records
- CNAME records
- MX records
- TXT records
- SPF records
- DKIM records
- DMARC records
Missing DNS entries can interrupt websites, email delivery, and third-party services after the migration.
Prepare Your Email Services
If your email is tied to your hosting account, make a plan before switching servers.
Verify:
- Mailboxes
- Forwarders
- Aliases
- SMTP settings
- IMAP/POP configuration
- Webmail access
Many migrations succeed technically but accidentally disrupt email because mail records weren’t transferred correctly.
Review Your SSL Certificate
Ensure your SSL certificate is available on the new server before changing DNS.
Confirm:
- Certificate validity
- Private key availability
- Intermediate certificates (if applicable)
- Automatic renewal settings
Your website should continue serving HTTPS immediately after the migration to avoid browser security warnings and maintain user trust.
Notify Your Team
If multiple people manage your website, let them know about the planned migration.
This includes:
- Content editors
- Developers
- Marketing teams
- SEO specialists
- Customer support
Avoid publishing new content or making major changes during the migration window to prevent data inconsistencies.
Pro Tip: Choose the Right Migration Window
Whenever possible, schedule your migration during periods of lower traffic.
Use your analytics platform to identify off-peak hours. Migrating when fewer visitors are online reduces the impact of any temporary issues and provides more flexibility to test the new environment before traffic returns.

Website Migration Day Checklist
Once you’ve completed your preparation, it’s time to begin the migration. Follow these steps carefully to minimize downtime and reduce the risk of errors.
Put Your Website Into Maintenance Mode
If your website is dynamic (such as WordPress, Magento, or an eCommerce platform), enable maintenance mode before starting the migration.
This prevents visitors from making changes while files and databases are being transferred.
Examples include:
- New blog posts
- Customer registrations
- WooCommerce orders
- Contact form submissions
- User profile updates
For static HTML websites, maintenance mode is usually unnecessary.
Transfer Website Files
Copy every file from your existing hosting account to the new server.
This includes:
- Website files
- Themes
- Plugins
- Media uploads
- Configuration files
- Hidden files (such as
.htaccess)
Always verify that file permissions remain correct after the transfer.
Export and Import Your Database
If your website uses a database, export it from your old server and import it into the new one.
After importing:
- Update database credentials.
- Verify table integrity.
- Confirm the correct character encoding.
- Test database connectivity.
A successful database migration ensures your website functions exactly as it did before.
Update Configuration Files
Many websites require updated configuration settings after migration.
Examples include:
- Database username
- Database password
- Database host
- API keys
- Cache settings
- File paths
- SMTP credentials
Double-check every configuration file before going live.
Test Before Updating DNS
One of the biggest migration mistakes is changing DNS before testing the new server.
Instead:
- Preview the website using a temporary URL or hosts file.
- Test every important page.
- Verify forms.
- Confirm user logins.
- Check the shopping cart (if applicable).
- Test search functionality.
- Verify images load correctly.
Never point your domain until you’re confident everything works.
Update DNS Records
Once testing is complete:
- Update your nameservers or A records. Google’s documentation also recommends testing your new environment before making DNS changes.
- Keep the old hosting account active during DNS propagation.
- Monitor propagation progress.
Although propagation is often much faster today, some networks may still cache old DNS records for several hours.
Post-Migration Checklist
Successfully moving your website is only the beginning. The next phase is verifying that everything functions correctly.
Check Every Important Page
Visit your:
- Homepage
- Contact page
- About page
- Services
- Blog
- Product pages
- Login pages
- Checkout pages
Look for:
- Missing images
- Broken layouts
- JavaScript errors
- Missing CSS
- Slow loading
Test Every Form
Verify all forms work correctly.
Examples:
- Contact forms
- Newsletter signup
- Quote request
- Support tickets
- Checkout forms
Confirm emails are delivered successfully.
Verify Email Functionality
Test:
- Sending emails
- Receiving emails
- Password reset emails
- WooCommerce notifications
- Contact form notifications
Email problems are one of the most common post-migration issues.
Scan for Broken Links
Broken internal links hurt both SEO and user experience.
Check for:
- 404 pages
- Broken images
- Missing downloads
- Incorrect redirects
Fix issues immediately.
SEO Website Migration Checklist
Protecting your search rankings should be a top priority.
Submit Your XML Sitemap
Generate a fresh XML sitemap and submit it through Google Search Console.
This helps search engines discover updated pages more quickly after the migration.
Check robots.txt
Ensure your robots.txt file:
- Exists
- Doesn’t accidentally block important pages
- References your XML sitemap
Many websites accidentally leave staging rules in place after launch. Google explains robots.txt best practices in its official documentation.
Verify Canonical Tags
Each page should contain the correct canonical URL. Google recommends using canonical URLs to consolidate duplicate content signals.
Incorrect canonical tags can confuse search engines and reduce visibility.
Verify Redirects
If URLs changed during the migration, create permanent (301) redirects.
Examples:
Old URL:
https://example.com/servicesNew URL:
https://example.com/web-hostingOld page → New page (301)
Avoid redirect chains and loops wherever possible.
Monitor Crawl Errors
After migration, regularly review Google Search Console for:
- 404 errors
- Redirect issues
- Soft 404 pages
- Server errors
- Indexing warnings
Resolving these quickly helps preserve SEO performance.
Track Rankings
Monitor your primary keywords during the weeks following the migration.
Small fluctuations are normal, but significant ranking losses should be investigated promptly.
Performance Optimization After Migration
A migration is the perfect opportunity to improve website speed.
Consider enabling:
- Page caching
- Object caching
- Browser caching
- GZIP or Brotli compression
- Image optimization
- Lazy loading
- HTTP/2 or HTTP/3
- CDN integration
Measure performance before and after migration to confirm improvements.
Security Checklist
Before declaring the migration complete, verify your website is secure.
Review:
- SSL certificate
- Automatic backups
- Web Application Firewall (WAF)
- Malware scanning
- Strong administrator passwords
- Two-factor authentication
- File permissions
- Security updates
Security should always be part of your migration—not an afterthought.

Frequently Asked Questions
How long does a website migration take?
A simple website may be migrated within a few hours, while larger websites or online stores can take a day or more depending on their size and complexity.
Will I lose my Google rankings after migrating?
Not necessarily. If the migration is carefully planned, URLs are preserved or redirected correctly, and technical SEO is maintained, rankings often recover quickly. Poorly executed migrations, however, can result in temporary or long-term ranking losses.
Can I migrate my website without downtime?
Yes. By preparing the new server in advance, testing it thoroughly, and updating DNS only after everything is ready, many migrations can be completed with little to no noticeable downtime.
Do I need to back up my website before migrating?
Absolutely. Always create complete backups of your files, databases, and any associated email accounts before making changes.
Should I keep my old hosting account active?
Yes. Keep your previous hosting account active until DNS propagation is complete and you’ve confirmed that your website, email, and services are working correctly on the new server.
Does website migration affect SEO?
It can. A properly managed migration preserves search visibility, while missing redirects, broken links, indexing issues, or major URL changes can negatively impact SEO.
