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.


Enter Duplicator in the search box and search.


Find Duplicator in the search results and click Install Now.


STEP 2: Activate Duplicator.

Click the Activate button when it appears to activate it.


STEP 3: Move the cursor to Duplicator from the menu and click Package.


STEP 4: Create a package.

▼ Click New on the top right


▼Basically, there is no problem with the default settings, so click the next button.


▼The scan results will be displayed. If there are no problems, click Build.


▼The build starts. It will take some time, so please wait without closing the screen.

▼When the completion screen is displayed, download both Installer and Archive.If you click One-click download, you can download both in succession, but depending on the browser, a confirmation screen for multiple downloads may be displayed.


If the download is complete, the pre-transfer preparations on the transfer source server are complete.

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.
When using a new domain > Please set a new domain.

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.)

Click here for how to check your nameservers.

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.

Transferring data to mixhost

Recommended security settings

In mixhost, the list of files in the directory is displayed as standard, but it may be a security risk when using the Duplicator, so we will disable the file list display.
Please check here for the setting method.

Uploading WordPress data

STEP 1: Use FTP software to connect to the mixhost server.

Please refer to here for how to set up the FTP software. FFFTP is used here as an example, but there is no problem if you use other FTP software.

STEP 2: Change the current directory to document root.

Double-click the document root of the original domain set on the server side and move to it.


STEP 3: Upload data.

After moving to the document root, upload the Installer (install.php) and Archive (zip file) that you downloaded earlier. The data upload is now complete.
