Even well-planned WordPress migrations can introduce unexpected issues. Plugin dependencies, custom integrations, email services, and ecommerce workflows may behave differently after a site is moved to a new hosting environment or rebuilt on a new platform.
This guide covers several common migration-related issues and outlines a practical approach to diagnosing and resolving them.
Issue Background
Following a WordPress migration, users began reporting multiple functionality problems affecting different areas of the website. These included broken workflows, missing plugin functionality, and unexpected changes in email behavior.
While some issues were directly related to the migration process, others were uncovered during post-migration testing and had existed previously within custom site functionality.
Comprehensive troubleshooting was required to separate migration-related issues from pre-existing problems.
Diagnosis
A detailed review identified several primary concerns:
- Email notifications were exposing long raw URLs after changes to email delivery services.
- wpDataTables functionality was unavailable because required components were missing.
- WooCommerce post-checkout intake workflows were no longer functioning correctly.
- Certain Gravity Forms customizations contained issues that predated the migration itself.
These findings highlighted a common migration challenge: not every issue discovered after a migration is necessarily caused by the migration.
Resolution Steps
Review email delivery workflows
Email systems should be thoroughly tested after migration, especially when changing providers such as SendGrid, Mailgun, or other SMTP services.
Where sensitive information appears within email links, tokenized URLs can provide a more secure and user-friendly experience.
After any email-related updates, notification workflows should be tested end-to-end to confirm proper functionality.
Restore missing plugin functionality
Migration projects occasionally reveal missing plugins, expired licenses, or disabled add-ons.
In this case, wpDataTables functionality depended on both the primary plugin and supporting integrations.
Administrators should verify:
- Required plugins are installed.
- Licenses remain active.
- Related add-ons are enabled.
- Data sources remain connected properly.
Repair WooCommerce checkout workflows
Custom ecommerce workflows often require special attention during migrations.
Order processing, intake forms, file uploads, and post-purchase actions should all be tested after launch.
Where custom functionality breaks, a dedicated plugin or MU (Must-Use) plugin can be used to restore critical business processes while maintaining compatibility with future updates.
Validate custom integrations
Plugins such as Gravity Forms frequently rely on custom code and integrations that may not be immediately obvious during migration planning.
Review all custom functionality and test form submissions, notifications, conditional logic, and integrations to identify any hidden issues.
Perform full regression testing
A complete regression test should be performed after every migration.
This should include:
- User registrations.
- Form submissions.
- Email notifications.
- Ecommerce transactions.
- Plugin integrations.
- Administrative workflows.
- Reporting and analytics functionality.
Testing all major user journeys helps uncover issues before they affect visitors.
Final Outcome
Through systematic troubleshooting, migration-related issues were identified and resolved while unrelated legacy issues were documented and addressed separately.
Email workflows were improved, plugin functionality was restored, WooCommerce processes were repaired, and critical site functionality returned to normal operation.
Successful WordPress migrations require more than moving files and databases—they also require thorough validation of every major workflow that supports the business.
