5 WordPress Migration Mistakes That Can Cause Website Downtime
Your new hosting environment is ready. The WordPress files have been transferred. The homepage loads perfectly. Then someone tries to place an order, and the checkout stops working. Website migrations often appear successful long before they're actually complete. Moving a WordPress website isn't just about transferring files between servers. A successful migration needs to preserve the database,…
When moving a WordPress website, success hinges on more than just copying files to a new server. Several critical factors must be addressed to prevent downtime. Five common mistakes that can lead to website outages are:
1. Failing to create a reliable backup. Simply having a backup file doesn't guarantee the ability to restore the website properly. A full migration involves the WordPress files, themes, plugins, media, database, configuration files, and server-specific settings. Before starting, verify the backup's validity and test the restoration process in a separate environment.
2. Changing DNS records before thoroughly testing the new site. Updating DNS right away can cause issues if the server has an incompatible PHP version, missing SSL certificate, or missing server extensions. Test the new hosting environment using a staging URL or local hosts-file override before altering public DNS settings. Lowering the DNS TTL doesn't ensure an immediate switch due to caching.
3. Ignoring PHP, plugins, and server compatibility issues. A website's performance depends on more than just its application files. Factors like PHP versions, database versions, server extensions, caching plugins, rewrite rules, and plugin requirements can all impact the outcome. Check plugin compatibility, review server logs, and test critical features before migration. Avoid combining multiple major upgrades during the process.
4. Neglecting email and dynamic data. Moving a website without considering email delivery or live data can disrupt business operations. DNS changes may affect email delivery even if the website appears fine. Online stores and booking systems may receive new orders or appointments during the migration. Coordinate a controlled final synchronization or maintenance window to avoid losing valuable information.
5. Not verifying the migration's success. Completing the DNS change and having the homepage load doesn't mean the migration is finished. Verify the functionality that matters most to your users, such as homepage and internal pages loading correctly, HTTPS and SSL certificates working, contact forms and transactional emails functioning, WordPress administration being accessible, images and scripts loading properly, login and checkout workflows operating, redirects and important URLs remaining correct, backups and scheduled tasks behaving as intended, and having a rollback plan in place.
Following a thorough migration checklist that addresses these five areas can significantly reduce the risk of website downtime during a WordPress migration.
