Choosing a WordPress hosting alternative—whether you're unhappy with performance, outgrowing shared hosting, or chasing better support—should improve your site. Yet most migrations introduce avoidable problems: broken links, missing emails, SEO drops, or extended downtime. These issues stem from repeatable mistakes, not bad luck.
This guide catalogues the seven most common errors site owners make when evaluating and switching WordPress hosts, along with the correct approach for each. Follow these practices to migrate smoothly and avoid the pitfalls that turn a simple host change into a week-long crisis.
Mistake 1: Choosing a Host Based Solely on Price
The lowest-priced plan often looks attractive until you discover why it costs less. Budget hosts typically oversell resources, restrict CPU usage with aggressive throttling, provide minimal support, or lock you into long renewal terms at much higher rates.
Common symptoms: - Site becomes unresponsive during traffic spikes - Support tickets take days to get basic responses - Surprise price jumps at renewal time - Severe restrictions on plugins, cron jobs, or email sending
Correct approach:
Evaluate hosting costs over the full renewal cycle, not just the introductory price. Compare these factors:
- Resource allocations: CPU limits, memory, I/O caps, and whether they're guaranteed or shared
- Support quality: Live chat availability, average response times, and technical expertise level
- Backup and restore: Frequency of automatic backups and whether restoration is included or costs extra
- Migration assistance: Whether the host offers free site migration or you'll need to hire help
A host that costs slightly more but includes staging environments, automated backups, and expert WordPress support often delivers better value than the cheapest option.
Mistake 2: Skipping the Pre-Migration Backup
Many site owners rely on their current host's backup system during migration, only to discover those backups are incomplete, outdated, or inaccessible once the account is canceled.
Common symptoms: - Database backup missing recent posts or orders - Media library files incomplete or corrupted - Plugin configurations lost - No way to roll back after discovering migration issues
Correct approach:
Create your own complete backup before starting migration work:
-
Export your database via phpMyAdmin or command line:
bash mysqldump -u username -p database_name > backup.sql -
Download all WordPress files including wp-content, themes, plugins, and uploads:
bash tar -czf wordpress-files.tar.gz public_html/ -
Document your current configuration: - PHP version and extensions - Active plugins and their versions - Theme and child theme - Permalink structure - Any custom .htaccess rules
-
Store backups in multiple locations: local drive, cloud storage, and a separate server. Never rely on a single copy.
-
Verify backup integrity by checking file counts and database table completeness before proceeding.
A plugin like UpdraftPlus or All-in-One WP Migration can automate this process, but always verify the backup completed successfully.
Mistake 3: Migrating DNS Before Files and Database
Changing DNS records to point to the new host before your site is fully configured there guarantees downtime. Visitors will land on a broken site, error page, or generic hosting placeholder during the transition.
Common symptoms: - Site shows "database connection error" for hours or days - Images and assets return 404 errors - SSL certificate warnings appear - Email stops working immediately
Correct approach:
Build and test the site completely on the new host before changing DNS:
-
Use the new host's temporary URL or preview domain to access the site before DNS changes. Most hosts provide a temporary URL like
tempurl123.newhost.comor allow you to modify your local hosts file:# Add to /etc/hosts (Linux/Mac) or C:\Windows\System32\drivers\etc\hosts (Windows) 123.45.67.89 yourdomain.com www.yourdomain.com -
Upload files and import the database using the new host's tools or command line.
-
Update wp-config.php with new database credentials.
-
Run search-replace to update old URLs to new server paths if needed:
bash wp search-replace 'https://oldhost.temp' 'https://yourdomain.com' --dry-run wp search-replace 'https://oldhost.temp' 'https://yourdomain.com' -
Test thoroughly using the temporary URL: navigation, forms, checkout process, login functionality, and image loading.
-
Install and verify SSL certificate on the new host before DNS changes.
-
Only after complete testing, update DNS records to point to the new host.
This approach ensures that when DNS propagates, visitors immediately see a working site.
Mistake 4: Ignoring Email Configuration
Email often breaks during hosting migrations because DNS changes affect MX records, and email accounts must be recreated at the new host. Site owners frequently discover email problems days later when customers complain about bounced messages.
Common symptoms: - Incoming email bounces with "mailbox not found" errors - Outgoing email from contact forms stops working - Email clients can't connect to mail servers - Email history and folders disappear
Correct approach:
Plan email migration as carefully as the website itself:
-
Document current email setup: - List all email accounts and forwarders - Note current MX records and mail server settings - Check whether email is hosted with the current web host or separately (like Google Workspace)
-
If email is hosted separately (Google Workspace, Microsoft 365, external mail service), your MX records can stay unchanged. Verify them before migration.
-
If email is hosted with your current web host, decide whether to: - Move email to the new host (recreate accounts there) - Keep email with the old host temporarily (update A records only, leave MX unchanged) - Migrate to a dedicated email service
-
Recreate email accounts at the new host before changing DNS, using identical usernames and passwords.
-
Update email client settings to use new server hostnames once DNS propagates.
-
For IMAP accounts, consider using a tool to migrate existing messages to the new server before switching.
-
Test email sending and receiving using the new host's webmail interface before DNS changes.
Always complete email setup and testing before updating DNS, and communicate the change window to anyone who depends on that email.
Mistake 5: Not Testing on the New Host's PHP Environment
WordPress sites often depend on specific PHP versions and extensions. Moving to a host with a different PHP configuration can break functionality silently—forms stop submitting, pages error out, or admin features fail.
Common symptoms: - White screen of death after migration - Plugin or theme features stop working - Fatal errors mentioning missing PHP functions - Admin dashboard becomes inaccessible
Correct approach:
Match and test the PHP environment before going live:
- Check your current PHP version in WordPress admin (Site Health) or via phpinfo: ```php
```
-
Verify the new host supports the same PHP version, or update your site to the new host's version before migrating.
-
Review required PHP extensions for your theme and plugins. Common requirements include: - gd or imagick for image processing - curl for external API calls - mbstring for multibyte character handling - xml and zip for various plugins
-
Test with PHP error reporting enabled on the new host before DNS changes:
php // Add temporarily to wp-config.php define('WP_DEBUG', true); define('WP_DEBUG_LOG', true); define('WP_DEBUG_DISPLAY', false); -
Review debug.log for any errors or warnings that appear during testing.
-
Test critical functionality: product checkout, form submissions, user registration, and any custom features.
-
Disable WP_DEBUG before updating DNS to production.
If the new host runs a newer PHP version, use a local development environment or staging site to test compatibility before migration.
Mistake 6: Forgetting About Cron Jobs and External Integrations
WordPress sites often integrate with external services: payment processors, email marketing platforms, CRMs, analytics, and CDNs. Migration can break these connections through changed IP addresses, API endpoints, or server configurations.
Common symptoms: - Scheduled posts stop publishing - Backup plugins fail silently - Payment processing errors increase - Analytics tracking stops - Email marketing forms disconnect
Correct approach:
Audit and update all external connections:
-
List all active integrations: - Payment gateways (Stripe, PayPal webhooks) - Email services (Mailchimp, ConvertKit) - CDN and caching (Cloudflare, KeyCDN) - Analytics (Google Analytics, tracking scripts) - Security services (Wordfence, Sucuri) - Backup services with remote storage
-
Update webhook URLs and API endpoints that include your domain or IP address.
-
Verify cron jobs are running correctly on the new host:
bash wp cron event list wp cron test -
Whitelist the new host's IP addresses in any services that use IP-based security.
-
Reconfigure CDN settings to point to the new origin server.
-
Update DNS records for subdomains used by integrations (like shop.yourdomain.com or api.yourdomain.com).
-
Test each integration individually after migration: process a test transaction, submit a form, trigger a backup.
Create a checklist of every external service your site uses and verify each one functions correctly on the new host before and after DNS changes.
Mistake 7: Canceling Old Hosting Too Quickly
DNS changes take time to propagate globally, and some visitors may still reach your old server for hours or days after updating records. Canceling your old hosting account immediately can leave those visitors seeing error pages.
Common symptoms: - Reports of site downtime from some visitors while others see it working - Intermittent errors that resolve themselves - Some email messages bounce while others deliver - Analytics show traffic drop that later recovers
Correct approach:
Maintain both hosting accounts during the transition period:
-
Keep old hosting active for at least 48-72 hours after DNS changes to allow full propagation.
-
Monitor DNS propagation using tools that check from multiple global locations to confirm the new records have spread.
-
Leave the old site functional during this period so late-propagating visitors don't see errors.
-
Set up a simple redirect on the old host after several days if you plan to keep the account longer:
apache # In .htaccess on old host Redirect 301 / https://yourdomain.com/ -
Check email forwarding during the transition to ensure no messages are lost.
-
Review analytics and error logs on both hosts to confirm traffic has fully shifted before canceling.
-
Download final backups from the old host before canceling, including email if stored there.
Only cancel the old hosting once you've confirmed DNS has propagated worldwide, all traffic reaches the new host, and you've saved final backups. Most billing cycles allow at least a month, so there's no urgency.
Pre-Migration Checklist
Before starting your WordPress hosting migration, verify you've completed these steps:
- [ ] Created complete site backup (files + database) stored in multiple locations
- [ ] Documented current PHP version, extensions, and server configuration
- [ ] Listed all email accounts, forwarders, and MX records
- [ ] Inventoried all external integrations and APIs
- [ ] Reviewed new host's resource limits and features
- [ ] Confirmed new host supports your PHP version and required extensions
- [ ] Set up staging or temporary URL access on new host
- [ ] Planned DNS transition strategy
- [ ] Scheduled migration during low-traffic period
- [ ] Notified team members of potential email disruption window
Conclusion
Most WordPress hosting migration problems stem from rushing the process, skipping testing phases, or changing DNS before the new site is ready. The correct approach—backup thoroughly, build completely on the new host, test everything, then change DNS—eliminates the majority of migration headaches.
Treat migration as a project with distinct phases: planning, building, testing, and cutover. Maintain the old hosting during transition, verify each integration works, and don't cancel anything until you've confirmed the new setup handles real traffic successfully. Follow these practices and your migration will be uneventful, which is exactly what a hosting change should be.
