WordPress Migrator "Failed to complete WordPress installation on the destination server" error
This error indicates that the WordPress Migrator was unable to automatically install a new WordPress instance on the destination server.
The most common reason for being unable to install a new WordPress is the presence of an existing application at the destination. When the WordPress Migrator attempts to install a new WordPress instance, it requires an empty folder to avoid conflicts and ensure that all necessary files and configurations are correctly set up. If there is already an application, such as an older WordPress installation or another CMS, it can prevent the Migrator from proceeding with the new installation. This conflict appears because the existing application may use the same folders that the new WordPress instance needs.
To resolve this issue, manually delete the existing application from the destination server. This involves removing all files and directories associated with the old application. It is essential to back up any important data before performing these deletions to avoid accidental data loss. Once the destination is free of any applications, you can restart the WordPress Migrator transfer process and it should now be able to complete the installation process without any issues.
