We will introduce how to migrate the server to mixhost using the WordPress plugin "All-in-One WP Migration".

See here for usage instructions.

The content introduced here is a method corresponding to general WordPress migration. Some services and customized WordPress transfers may not be successful.

  • Server transfer involves transferring WordPress data and setting up your own domain.
  • We will be using a WordPress plugin called All-in-One WP Migration for this task.
  • Please apply to mixhost first.
  • Until the transfer is completed, please continue the contract of the transfer source server.
  • It may fail if there is insufficient free space on the source server. If it doesn't work, please ensure you have enough free space.
  • Please do not change the nameservers of your own domain before the transfer work.
  • Please check in advance regarding the change procedure.

Preparations on the source server

Before the transfer work, first export the data from the source server you are currently using and download it.

WordPress updates

Before starting work, we will update the WordPress currently being used on the source server to the latest version in order to prevent problems.
If you are already using the latest version, you can skip this step and there is no problem.

STEP 1: Click Dashboard > Update on the management screen.


STEP 2: I have a new version of WordPress. If you see, click Update Now.


Once the update is complete, proceed to the next step.

Install & Export WordPress Plugins

STEP 1: Log in to the WordPress management screen, move the cursor to Plugins on the left, and click Add New.


STEP 2: Enter All-in-One WP Migration in the search window on the upper right and search.


STEP 3: Click Install Now on the right side of All-in-One WP Migration.


STEP 4: After installation is complete, click Activate.


STEP 5: Open All-in-One WP Migration export from WordPress left menu and click "Advanced Options".


STEP 6: Check the items as necessary and click "Export destination".


STEP 7: When the menu expands, click File.


STEP 8: Check the export processing completion screen.

It may take several seconds to several tens of minutes depending on the site, but please wait without closing the screen.


When completed, the screen will change to the one below, and the amount of data will be displayed inside the green download button.
Please keep in mind that this file capacity is required for import work at the transfer destination.
Also, the downloaded wppress file will be used in a later step, so please save it in an easy-to-find location.


Export is now complete.

*Items excluded from the export target and images and css in locations other than the template will need to be transferred using FTP after the transfer is complete.
Media files uploaded from WordPress are usually saved in the "/wp-content/uploads" folder under the WordPress installation directory.

Preparations on mixhost

After exporting and downloading on the transfer source server, mixhost will prepare in advance.

Setting up your own domain

Set your own domain that you want to transfer.

When transferring without changing the URL > Please set the domain currently in use on the transfer source server.

Access settings for your own domain

In order to proceed with the transfer work, it is necessary to enable access to the mixhost server with your own domain from your PC environment using one of the following methods.

  • How to change nameservers [for beginners]
    Change the name server set by the domain management company to that of mixhost. This method is less risky and easier but will result in a period of inaccessibility to your website.
  • How to use the hosts file [For advanced users]
    Edit the hosts file on your PC and temporarily set it so that you can access the new server from your PC using the domain name. Since it edits the settings of the customer's PC, there is a risk of incorrect settings, but it is possible to transfer the website without interruption.

Regarding the method of using the initial subdomain of mixhost, we do not recommend it because the plugin will change all the URL settings inside WordPress to the subdomain.

[Method 1] How to change nameservers [For beginners]

Please change the nameservers on the website of the domain management company you are currently using and wait for a few hours to 72 hours. (If you do not know how to change it, please contact the domain management company.)

It is common for the changes to be reflected in a few hours, so please check regularly.

If you see a screen that says Index of / when you access with your domain name, proceed to transfer data to mixhost.

[Method 2] How to use the hosts file [For advanced users]

Please refer to the setting procedure of the hosts file and set it.

After setting up, if you see a screen with "Index of /" when accessing with the domain name, proceed to transfer data to mixhost.
