Depending on the size and complexity of the database involved, there are a number of challenges that can arise during the WordPress data migration process. One of the most common is time-out of the phpMyAdmin tool, a popular plugin used for WordPress database management.
To move a WordPress website, the data must first be exported to a dump file then imported into the empty database waiting on the new host. When working with a large database, phpMyAdmin often proves to be incapable of handling the export/import tasks. In this case, the support teams at the old and new hosting providers must be called in to create the database backup and import the dump file.
Migrating a WordPress website is a serious undertaking that requires effort, patience, and expert knowledge of WordPress code.
Another common issue is difficulty with reconfiguring the wp-config.php file after the database has been successfully transferred. The database settings will need to be altered to match the new database name, user, and password. Then the DNS settings have to be changed to reflect the domain’s new location. Often, and especially if too little testing has been done, the website may not open or work correctly on the new server.
An additional source of error at this stage in a database move is mismatch between existing file permissions and the requirements of the new host. If you are going to a high-quality hosting provider and your file security is too low, you will get an Internal Server Error message.
On the other hand, moving to a low-level provider could result in all your permissions being set at 777, which gives anyone access to your files and is an extreme security risk. Both the reconfiguration and file permission problems can be sorted out, but it takes time and effort.
The best way to reduce risks and avoid problems during a WordPress data migration project is to come in to the job with plenty of experience, knowledge, and resources at your disposal. The objective is to keep your data protected, carry off a smooth, trouble-free migration process, and come out the other side with your site traffic count and SEO ranking holding steady if not improving.
