How to Migrate WordPress Multisite Subdomain to a Single Site

0

WordPress Multisite is a platform usually used by corporate houses, institutions or philanthropic organization, whose organization is spread across length and breadth of a country. They usually give prominence to each of the regional headquarters and manage them through the WordPress Multisite Subdomain in a form of subsites.

What is a WordPress Multisite?

Multisite is a big network of individual sites, where a number of independent sites join together in a form of group. They work from a single platform.

The WordPress multisite may have one main domain and multiple sub-domains or directories where individual sites are hosted.

In a multisite network, subsites are either individually controlled from the Admin Control panel or all the subsites are combined together to be controlled from the Network control panel.

Why migrate a WordPress Multisite Subdomain?

During the management and control of multi-sites, a time comes, when a need arises to segregate the sub-domains or subsites from the multisite and move some of them to a single site of another host.

There may be several reasons for doing so. some of them are as follows.

  • The subsite may outgrow the network in terms of posts comparing to other subsites.
  • The subsite may outgrow other sub sites in terms of volume of traffic.
  • SEO considerations of the multisite may force it to split.

Migrating WordPress Multisite Subdomain to a Single Site is an event which occurs rarely in a bloggers life. So all the bloggers are not confident in performing such tasks.

However, if you go through the process once, there is hardly anything to panic and you will gain tremendous confidence to perform the task if you are called to do so the next time.

In the following paragraphs, I am going to deliberate the subject step by step so that it is easy to understand and easy to comply.

The process of migrating WordPress Multisite Subdomain to a Single Site can be performed in three modes. The automatic mode, auto-manual mode and by manual mode. All these modes are explained below in detail.

Before you do anything, first take the backup of the whole multisite. Remember precautionary measures are of paramount importance to restore the sites, in case some untoward incident.

Moving WordPress Multisite Subdomain in Automatic Mode

Migrating a WordPress Multisite Subdomain to a subsite of a different host in an automatic mode is possible through only plugins.

A normally paid version of these plugins allows you to perform the task. In this series Duplicator, Backup Guard, WP Migrate DB Pro, and Backbuddy plugins are some of the plugins who are known to accomplish the task of migrating subsites from a multisite platform very conveniently without much intervention of the blogger.

They do it all in an automatic mode.

Moving WordPress Multisite Subdomain in Auto-manual Mode

Auto-manual mode of migration of WordPress Multisite Subdomain, involves some of the task to be done manually, whereas rest all is done automatically.

You can perform the migration in this mode simply following the under mentioned steps.

Auto-manual mode migration

1. Go to the subsite pane of the multisite, which you want to migrate.

2. Go to Tools > Export option.

3. Check All content option on the Export panel.

4. Save all the contents of the subsite in an XML file on your Desktop.

5. Now go to the new host site and install WordPress. You can take help of article how to install WordPress.

RewriteCond %{HTTP_HOST} ^subdomain\.OldDomain\.com$ [NC]
RewriteRule ^(.*)$ http://www.NewDomain.com/$1 [L,R=301]

Removing Older WordPress Multisite Subdomain

Once you are completely happy that everything’s working as it should be, remove the site from your Multisite installation. I’d recommend leaving this a week or so in case you spot anything that hasn’t moved across.

In the meantime, you can configure the old site’s domain to map to the new one, either by using a plugin or in CPanel. I will suggest ‘Safe Redirect Manager’ plugin for 301 permanent redirections.

Phew! It was a long and slightly complicated process, but you’ve done it.
