Unlimited Extension User Guide

The Unlimited Extension adds to the functionality of the All-in-One WP Migration plugin by allowing you to import backups larger than 512 MB. The tool can be used in conjunction with any other All-in-One WP Migration plugin extensions to facilitate the direct import of your websites/network of sites from your cloud/storage.

The tool is a plugin extension, so you must install the All-in-One WP Migration plugin for it to function.

For more information on installing the Unlimited Extension, go to: https://help.servmask.com/knowledgebase/install-instructions-for-unlimited-extension/

This tutorial contains details of:

  • Import using Unlimited Extension
  • Backup Scheduling using the Unlimited Extension


1. Import Using Unlimited Extension

You start the import procedure by selecting the Import option from the All-in-One WP Migration plugin menu:

Selecting this option opens a new window where you can select a backup source:

Depending on the option you select, you will then redirect to the cloud storage or to the specific file. The import process will begin normally, but you will be able to import a backup larger than 500 MB in the same way that you would a smaller backup.

When you select a backup to import, the following steps occur:

The import process includes an additional step that warns you that the new backup will overwrite your website’s database, media, plugins, and themes. This is your last chance to cancel the process. After clicking “Proceed,” you will not be able to stop the import process.

When finished, a successful import will show the following 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.

  5. Heather Feuerhelm

    I am trying to upgrade this extension, but i keep getting the error message: “Update Failed: Could not create directory.” How should this be handled?

  6. Gregory Motta

    I just purchase your unlimited extension and have achieved 0% database restoration after 20 minutes. I am using Amazon AWS as my hosting. Is this not compatible?

    1. Pim J. Iliev

      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.

    I did a back up prior to my provider upgrading my php from 5 to 7. I did use the plugin to do a full back up prior. BEFORE I spend money and purchase, one, will I have to go find all of the plugins I had before installed? Or better question, what all exactly is restored? The pages and their content, layouts, settings, plugins, themes? I’m already over budget, so please let me know what to expect before I go and dig deeper for more funds. (I just don’t want to have that conversation with my partners)

    1. Pim J. Iliev


      If you did a full backup of your website, everything within wp-content has already been included in the backup.
      Pages, content, layouts, and settings are stored in the database. We have a tool (http://traktor.servmask.com) that you can drag and drop the backup and browse to see if everything you need is there.
      On restore, everything you see in the backup will be restored.

      Hi David,

      Go to your server via FTP and rename /app/public/wp-content/plugins/revslider to /app/public/wp-content/plugins/revslider-bak
      The site should be working now.
      Update revslider to the newest version and enable it.

    Me gusto…


    Si tienes problemas para migrar sitios grandes, solo sube tu archivo de respaldo por FTP a la carpeta donde se hacen los respaldos, sobre todo su tu servidor es compartido ya que estos son mas limitados en su capacidad para subir archivos.

    I have Unlimited version of this plugin to migrate a WP website, but some tables and files are missing although I’ve received the message informing me about the successful installation.
    Can you please guide me what I should check in order to diagnose this issue?(log files, etc)

    Thank you!

    1. Pim J. Iliev

      Hi Patrick,

      Please log in using cPanel File Manager or FTP via FileZilla and download your backup directly from wp-content/ai1wm-backups.

    I have the unlimited extension, but when I try to import, I get a message that I must “update the plugin”.
    I go to my plugins page and check for updates, but there is none.
    \All-in-One WP Migration Version 6.85, All-in-One WP Migration Unlimited Extension Version 2.22

    Hi Servmask,

    I purchased the Unlimited Extension, installed the zip.
    Question 1: do both basic and unlimited plugins show up in the Plugins list page?
    Question 2: where do I enter Purchase ID? – cause I’m not sure if the unlimited is working (see Q 3 below)
    Question 3: When I try to import, it says “Maximum upload file size: 128 MB”, not unlimited (my files are 160M.)

    1. Pim J. Iliev


      You will have to install both plugins – basic version (All-in-One WP Migration) and Unlimited Extension.
      Purchase ID is not needed. Just make sure you have both the basic and Unlimited Extension installed and the message in your Question 3. will not show up.

      If you have further questions, please contact us at support@servmask.com

    Hello, I have installed the Unlimeted Extention.
    Both plugin are active.
    I still get the message:

    Unable to import

    The file that you are trying to import is over the maximum upload file size limit of 512 MB.
    You can remove this restriction by purchasing our Unlimited Extension.

    I have already de/reactivated the plugins.

    What can I do?

  17. Jose Soplanucas

    I have the version 2.29, & I m getting a message that I have to install the plug in. When I try to update it using the option in the WordPress plugins page, nothing happens. When I try to download the last version, I get a message saying that the installation failed because I already have the folder. When I try to delete the plugin using the options in WP plugins page, nothing happens.
    This issue is blocking me from updating other plug ins, like Yoast SEO.
    How should I proceed?
    Thank you!
