Unlimited Extension User Guide

Unlimited Extension extends the functionality of All-in-One WP Migration plugin, allowing you to import backups larger than 500 MB. The tool can be used in combination with any other All-in-One WP Migration plugin extensions to facilitate importing your websites/network of sites directly from your cloud/storage.

The tool functions as an extension to the plugin, so All-in-One WP Migration plugin is required to be installed for it to work.

  • Import using Unlimited Extension


1. Import Using Unlimited Extension

The import process is initiated from the Import option in All-in-One WP Migration plugin menu:

Selecting this option opens a new window where you can chose where to import a backup from using the dropdown menu:

You will then be redirected to the cloud storage or to the specific file – depending on the option that you have chosen. The import process will start in the regular way, but you will be able to import a backup larger than 500 MB in the same manner you would import a smaller one.

Choosing the backup for import will start the process:

The import has an additional step which warns you that your website will be overwritten by the new backup including database, media, plugins and themes. This is the last opportunity to cancel the process. After pressing ‘Proceed’ you cannot stop the import process.

When finished, a successful import will display this message:

    It’s done automatically. 🙂 When you “up-load” and activate the plugin, you should get a notice that there’s a newer version. Since you purchased it you’ll be fine 🙂

    Thank you for your question.

    In order to update Unlimited extension, you may go to Plugins page inside your WordPress installation in order to list all installed plugins.
    Then locate the application and see if there is an indication on its line that a newer version is available. If there is – there will be a link for updating ‘Update Now’, you will need to click on this link to proceed with the update.

    If there is no newer version than yours, there will be ni indication for a possible update.

    Hi Becca
    If you don’t get a notification that the plugin needs updating, please click on “check for updates” under the plugin name on the plugins page and install any updates provided.

    I am getting an error that states that I need to update my plugin for the migration to another site but it appears the plugin is current. When I select “check for updates” it spins and does nothing.

      Hi Gregory,

      What is your PHP version?
      If your migration appears to be getting stuck, can you try to open another browser tab of your website and let us know what you find?

    I just purchased the unlimited extension to the plugin and it’s unable to activate the plugin citing a fatal error:

    Fatal error: require_once(): Failed opening required ‘/var/www/vhosts/cherokeesteel.com/httpdocs/wp-content/plugins/all-in-one-wp-migration-unlimited-extension.php_/constants.php’ (include_path=’.:/opt/plesk/php/7.2/share/pear’) in /var/www/vhosts/cherokeesteel.com/httpdocs/wp-content/plugins/all-in-one-wp-migration-unlimited-extension.php_/all-in-one-wp-migration-unlimited-extension.php on line 51

    I’m in need of the extra file size to import a backup of my website and that was my reason for buying the unlimited extension to begin with. Now I’m kind of stuck because I need to restore my website from that larger file.

    Any help you can offer would be greatly appreciated.
