Multisite Extension User Guide

The All-in-One WP Migration plugin is required to be installed and activated to use the Multisite Extension.

For more details about installing the tool, you can visit:

This tutorial contains details of:

1. Export and Import process steps common for all cases

1.1 Export with WordPress Multisite installation

The export process for either an entire multisite network or a selection of one or more is initiated from the Export option in the All-in-One WP Migration plugin menu:

Once you have selected the sites to export, you can choose to create an export archive as a file that will be saved in your Backups directory, or you can choose to save it to the cloud if you are using a cloud extension:

Once the download is complete, you will receive  a message that will also give you the option to download your file locally.

1.2 Import with WordPress Multisite installation

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

Alternatively, you can directly restore an archive from the Backups page:

When the import process is successfully completed, you will be reminded to save your permalinks.

2. Export a WordPress multisite network and import it to an existing one

2.1 Export a multisite network

The Export page will allow you to choose what you want to include in your export:

To export the entire network of subsites, choose the ‘network (all sites)’ option as shown in the screenshot. The archive then will contain the entire network, including all your subsites with all their data. You can then select where you choose to export the site to and start the export process.

2.2 Import a multisite network

The import will overwrite the entire network with the imported file. The process will overwrite your database, media, plugins and themes. It is recommended that you have a backup of your existing site before overwriting it.

After starting the import, you will be asked for confirmation to continue:

To confirm the import, press Proceed. This will start the import process and you will not be asked for any further confirmations.

3. Export a subsite from a multisite network and import it to a subsite

3.1 Export a subsite from a multisite network

To export a single subsite from your WordPress multisite network, you need to select it in All-in-One WP Migration plugin export page. After that, proceed with the export in the usual way. The process will create an archive containing only the selected subset and its data.

3.2 Import a subsite to a subsite of a WordPress multisite network

Existing subsite data on a subsite that you choose to overwrite will be replaced by the imported file, including the database, media, plugins and themes. This import will not impact the rest of your multisite network. It is recommended that you have a backup of your subsite before proceeding.

The following message will be displayed for confirmation to proceed:

After the confirmation step you will be asked to enter the URL that the imported site will use:

Enter the name that your newly imported subsite will use into the URL. If you chose to import to a new subsite, one which previously didn’t exist in your multisite network, a subsite with the new name will be added to the network. Press Continue to start the import.

4. Export several subsites and import them into an existing WordPress multisite network

4.1 Export several subsites from a multisite network

To export more than one subsite, you need to choose each by URL in the Export page of  the All-in-One WP Migration Plugin:

The selected subsites will be added to the archive with all their data. The exported archive will only contain the subset data ( media, plugins, database and themes ) and not the data at the multisite network level.

4.2 Import several subsites, but not a whole network

The imported subsites will replace databases, themes, plugins and media in the subsites they are imported into. The process will affect only the subsites selected, not the whole multisite network. It is recommended that you have a backup of your currently existing subsites before importing new subsites.

You will see the following confirmation:

After pressing proceed, you will be asked to enter the URL for the destination of each of the newly imported subsites, one site at a time:

Once the URL for the last of the subsites is entered and the continue button is selected, the import will start.

5. Export a subsite from a multisite network and import it to an existing standalone site

5.1 Export a subsite from WordPress multisite network

The exporting process of a single subsite from an existing WordPress multisite network is the same as the one described in part 3.1 of this tutorial. The export will create an archive containing only the selected subset and its data.

From the All-in-One WP Migration plugin Export page, select the subsite that you want to export and start the export.

The process will create an archive containing only the selected subsite and its data.

5.2 Import a subsite into standalone WordPress website

When you import a subsite to a standalone WordPress website, your website database, media, plugins and themes will be replaced by those of the imported subsite. It is recommended that you have a backup of your website before you start the import process.

To confirm and proceed with the import press Proceed.

The import process will replace your whole website with what was previously a subsite.

6. Export a standalone WordPress website and import it into a multisite network

6.1 Export a standalone WordPress website

Exporting a standalone website with All-in-One WP Migration plugin is simple, just select your destination on the Export page to start the export:

The plugin starts the export and sends the archive to the chosen destination.

6.2 Import a WordPress standalone website to a multisite network

Importing a standalone WordPress website into a network of sites does not affect the rest of the network, just the subsite that you overwrite, if any.

To confirm the import, press Proceed.

You will be asked to enter the newly imported website name that will be used in the URL:

The standalone site import will replace database, media, themes and plugins only in the subsite it is imported into. The process does not affect the rest of the multisite network. If you chose to import to a new subsite, one which previously didn’t exist in your multisite network, it will be created and added to the number of subsites in the network. For a new subsite, no data on your existing sites will be overwritten.

    Subsite and Subdomain are two multisite specific terms.

    Subsite =;;

    Subdomain =;;

    Does your plugin work with subdomains?

    1. Anna Angelova

      Thank you for your question.
      Yes, our plugin supports subdomains during export and import with multisite extension.

  2. Camilo Buitrago

    After importing a subsite I changed the folder to be the root domain. Example:

    After doing this I lost access to the network as the super admin doesn’t work anymore.

    I was working in my local environment so there’s no problem but my plan was something like this:

    1. Import the first site and put it on the root domain
    2. Import the other two and put them as subfolders.
    3. Export the whole network.
    4. Install on the production server.

    How can I avoid losing access to the super admin because on the original site there’s no super admin because it is a normal WordPress install.

    1. Anna Angelova

      Thank you for your question.

      If you export from a standalone WordPress site you can import it as a subsite of the Multisite Network, and in that case
      you will lose access to the super admin.
      Can you please tell if you are importing the first site from a standalone WordPress site or from a Multisite Network subsite?

      Thank you in advance

    Can I:

    1/ Export from standard WP site and import as multisite subsite?

    2/ Export multisite subsite and import into standard (non multisite) WP site?

    Thanks, just checking 🙂

    1. Anna Angelova

      Thank you for your question.

      On 1/
      Yes, you can import a standalone WordPress site into a Multisite Network subsite – this is described in p.6 of the current User Guide.
      On 2/
      Yes, you can export a subsite from a Multisite Network and import it as a standalone. This is described in p. 5 of the current User Guide.

      Hi Cheryl
      The find and replace is an advanced function that you don’t need to use in a normal backup migration. It will replace all iterations of the term in the find box with the term in the replace box. It should be used with caution.
      Kind regards

  4. Chris Raudabaugh

    Is it possible to export and import on the same wordpress multisite cloning a site to a different domain. Eg. export and import into

    1. Lesley Arnold

      Hi Chris
      The plugin allows you to export a subsite of your choice and then import any backup of a subsite or standalone site in to your multisite network at the destination site of your choice.
      Kind regards

  5. L Dixon

    I have imported a standalone site into a multisite but it has changed to 2016 theme. I can make changes in Appearance > Customise and it says it’s saved but no changes are saved. Same in Settings – if I change settings (eg site name and strapline) I can’t save them.

    1. Lesley Arnold

      Hi L
      Can you email us at support at servmask dot com so that we can help to troubleshoot the issue?

  6. Boris Otasevic

    We are considering purchasing your multisite and dropbox extensions. Primarily to make duplicates of our single-site WP system to one multi-site WP system, periodically. Before we do that I would like to ask few questions:

    1. We don’t use default WordPress db table prefix (wp), but instead something else. Will that affect process of importing standalone WP as sub-site to multisite WP system?

    2. Do you have a list of plugins which might affect or create problems in migration process?

    3. Is it possible to set up scheduled backup process with cron job?

    4. Is it possible to have local (on server) backup file your plugin creates be deleted automatically, after preset period of time (X hours, days)?


    Boris Otasevic

    1. Pim J. Iliev

      Hi Boris,

      Thank you for getting in touch.
      That will not affect the process since the plugin detects the table prefix from wp-config.php file.
      We have our incompatible plugins listed here If you have any of them installed, just make sure you deactivate it before export.
      Our Dropbox Extension includes the auto-backup feature. Please check out
      The Retention Settings (on the Dropbox Settings page) can be configured to limit the numbers and the total size of the backups.

    We have WP multi site setup has sub domain and tables for sub domain in the same database.
    for Example:

    Above site does share same plugin and themes of wpms installation and same database. Now I want to export the above each site to standalone wordpress installation.

    Does your plugin work in this situation? I ask this question because of the screenshot you have posted only have sub site.

  8. Patricia

    Good Morning,

    I have a standalone site that needs to be migrated into a multisite. The site is fairly complex, it’s a virtual community of practice with over 300 users. We are using BuddyPress, BBpress, BuddyPress docs and several other plugins. Can your software handle a complex site? How are the users handled? All of our user’s profiles include xprofile types. Does the plugin retain author and editors posts or is a manual intervention necessary to associated users with posts and forum/topic replies? The multisite we’d be transferring this single site to is a brand new site. This site will be the only existing site transferred.

    1) with regards to standalone > multisite migration. What will happend with the plugins of the standalone site, if not part of the network?
    > we don’t want external plugins/themes to be added to our network..

    2) on our multisite we have mapped domains. we want to use your plugin to create a staging, but wihout mapped domains. How to go about this?

    mapped domain:

    1. Pim J. Iliev

      Hi Robert,

      1 – The active plugins will be imported and activated on the site.
      2 – During import, the plugin will ask you about site name, you can leave it as is to use the auto-specified site URL, or choose your own.
      There is nothing additional or custom that needs to be done.

      1. Dan Sudermann

        So if I understand correctly, even Plugins and Themes that are not enabled by the SuperAdmin of the network will be installed with this method? Will they be installed globally, so all subsites will then gain access to those plugins or how exactly are they imported?

        1. Yani I

          It depends on the content that you are exporting. If you are exporting a particular site then only themes and plugins that belong to that particular site will be included in the backup.

  10. Juli

    Hi there
    Just bought the multisite extension and wanted to ask the following:

    Can copy/clone Domain A to Domain B the following way
    Backup A without find/replace
    import in Domain B

    Do the multisite extension ask me for the new domainname on import?

  11. Dave Hooper

    Is there a way to import the main domain wordpress site? The subdomains I understand, but the actual domain is important in our network. I’d like to use a subdomain as a staging site and then export that and import it onto the (non subdomain) main domain.

    1. Pim J. Iliev

      Hi Dave,

      Yes, you can import into the main site in the Multisite network.
      During the import process, you will be allowed to select an existing subsite, main site or new subsite that you want to import into.
      You will have to select the main site to be imported to.

  12. Steven

    Hi, I bought a copy of multisite plugin for a project. Most of my projects are single sites. Can I use the multisite plugin for just single sites? Just don’t want having to purchase two different plugins.


    1. Pim J. Iliev

      Hi Steven,

      Yes, you can install Multisite Extension on your single sites to allow unlimited file size upload and enable the “Restore” functionality.

  13. Pamela

    The changelog notes the following: v3.64 12/20/2018 Added:
    Added Export only users that belong to particular subsites on export

    This is of critical importance to my project – so I would like to confirm please that when exporting a multisite single blog to standalone installation, only those users associated to the single blog can be exported.

    Thank you!

  14. Chris Schwehm

    Hi, I did review the comments so far but I want to make sure this will do exactly what I need before purchasing. I have a multisite set up with several unique domains (e.g., domain2,edu, etc.) I want to migrate these domains one at a time to a new multisite server because the old server is very outdated. Will this tool allow me to do that with only exporting an individual domain from one server, importing to the new server and then updating the DNS record w/o having to edit any of the exported info?

  15. Yuta

    I purchased your Multisite Extension for WordPress 6month ago.
    But I stopped the subscription last week.
    Please let me know How long can it be used?

    Thank you very much.
