All-in-One WP Migration is a popular WordPress backup and migration plugin. Large imports can fail when PHP limits are too low, even if the plugin itself allows the file.
Example .htaccess values
php_value upload_max_filesize 128M
php_value post_max_size 128M
php_value memory_limit 256M
php_value max_execution_time 300
php_value max_input_time 300
Example PHP settings
@ini_set('upload_max_filesize', '128M');
@ini_set('post_max_size', '128M');
@ini_set('memory_limit', '256M');
@ini_set('max_execution_time', '300');
@ini_set('max_input_time', '300');
Hosting limitations
Shared hosting providers may ignore some directives. If the limit does not change, adjust it in the hosting panel or contact support.
Migration safety
Always keep a local copy of the backup and confirm available disk space before importing.
