The All-in-One WP Migration plugin may fail to export or import due to a lack of disk space.

This means that your WordPress installation server, whether local or remote, lacks sufficient space for the plugin to create and store a backup file or import from a destination backup. In such cases, the All-in-One WP Migration plugin does not have enough space to create and use temporary files during the import or export processes, or to save the newly created backup.

This error may appear due to a variety of factors, including hosting restrictions (insufficient disk space on the server) and 32 bit PHP installation on the server.

Hosting restrictions limit the amount of space you can use on the server that hosts your website. The amount of storage your users use can change or update by the hosting provider; as a result, you must communicate this with them.

In such cases, you must keep track of the available space on your WordPress installation server. In order for both the import and export to work properly, the available space should be at least equal to the size of your WordPress website. You can see how much it is by looking at the size of the directory in which the WordPress installation is located, in the same way that you check the size of all files and folders – using the right click button and looking at the value of the Size property:

Export and import should work if the available space is at least as big as your website.

File size restrictions may also occur as a result of the PHP 32bit version installed on the server. The maximum upload file size for the 32bit version of PHP is 2GB. This means you can not create, upload, or use backups larger than 2 GB. This issue is related to the PHP installed on the server where your website is hosted and, as a result, must be communicated with the hosting provider as well.
