Moving a WordPress website is no longer a nightmare. If you are looking for Duplicator clone WordPress website step by step solution, then this is your final stop. I once spent all night migrating a website, struggling with broken FTP and database configurations. But since knowing Duplicator, everything only takes about 15 minutes of sipping a cup of coffee. This plugin helps you "package" your entire website - from source code, interface, plugins to database - into exactly two single files. Cloning or moving hosting is now as easy as pie, even if you are not familiar with code.
Instructions for duplicating a WordPress website using Duplicator (4 steps for newbies)
To perform how to clone a wordpress website with Duplicator, you only need to go through 4 basic steps: install the plugin to create a data package, download the file to your computer, upload to a new hosting and run the automatic installer.
This is the fastest and safest way to copy a wordpress website that I always apply at Pham Hai. This method helps you clone a wordpress site without code, completely eliminating cumbersome manual operations. Below is duplicator usage instructions with detailed every click.
Step 1: Install the Duplicator plugin and create a backup "Package".
The first step is to install the tool and tell it to pack all of your current website data into a single compressed file.
First, you need to log in to wordpress admin to install the plugin. On the WordPress dashboard screen, go to Plugins > Add New, type in search "Duplicator" and click install, then activate.
This is the most standard duplicator plugin installation instructions. After activation, look at the menu on the left, select Duplicator > Packages and press the Create New button in the right corner. The system will automatically scan the entire source code, interface (themes), plugins (plugins) and database to ensure website capacity is within a safe level. If everything says green (Good), you just need to press Build for the plugin to start creating the installation package (package).
Step 2: Download the Archive and Installer files to your computer
After the Build process is completed, you need to download the two most important files that Duplicator just created to your personal computer.
At this time, two download buttons will appear on the screen. Please click to download both files:
- File archive: Thường có định dạng
.ziphoặc.daf, chứa toàn bộ dữ liệu website của bạn. - installer.php: Đây là file kịch bản ma thuật giúp bung nén và tự động cấu hình mọi thứ trên máy chủ mới.
Save these two files in an easy-to-find folder on your computer.
Step 3: Upload 2 files to new hosting and create an empty Database
The next task is to upload the two files you just uploaded to the "new home" and prepare an empty database to store the information.
Bạn có thể đăng nhập vào cPanel hoặc DirectAdmin của hosting mới, mở công cụ File Manager và upload cả hai file vào thư mục gốc (thường là public_html). Nếu file quá lớn, bạn nên dùng phần mềm FTP như FileZilla để tải lên cho ổn định. Nếu bạn chưa chọn được bến đỗ mới, hãy tham khảo danh sách hosting cho wordpress tốt nhất mà mình từng tổng hợp.
Next, go to MySQL Databases on hosting to create a new database, a new user and grant full rights (All Privileges) to that user. Remember to write down the Database Name, User and Password in Notepad because we will need to use it in the next step. (Pro tip: You can also use Softaculous to quickly create a database if your hosting supports it).
Step 4: Run the "installer.php" file and complete the recovery process
The final step is to run the installation script to extract the data and automatically change the old paths to the new paths.
Bạn mở trình duyệt web và gõ địa chỉ: tenmiencuaban.com/installer.php. Giao diện cài đặt của Duplicator sẽ hiện ra. Tại đây, bạn nhập các thông tin database trống vừa tạo ở Bước 3. Nhấn Test Database để kiểm tra kết nối, nếu báo "Pass" thì bạn nhấn Next.
The system will automatically extract the compressed file, update the wp-config.php file and replace a series of old URLs with new domain names. This is the secret to help transfer wordpress to new hosting without errors that technical people often use. After running, you just need to log back in and check the results of recovering wordpress website with duplicator.
Why and when do you need to "clone" a WordPress website?
Website cloning is often done when you need to switch servers, create a secure testing environment, bring projects from your personal computer online, or simply make a backup.
As a webmaster, I realize that the utility of Duplicator plugin does not just stop at cleaning house. It is a multi-purpose tool that effectively supports website management and website maintenance on a daily basis.
Moving WordPress website to another hosting (a common occurrence)
When the current hosting is too slow, crashes or has poor support, moving is required to maintain traffic and SEO.
The process of moving a wordpress website to another hosting was very difficult in the past. But with Duplicator, host switching happens extremely smoothly. All link structures and article images are kept intact, ensuring the website works again immediately on the new server without missing a beat.
Create a staging site to test new features without fear of "crash" the main website
Staging site is an exact copy of the main website, placed in a hidden link so you can freely install and test new code.
If you plan to install a new theme or update WooCommerce, never do it directly on the actual website. Let's create a wordpress staging site using duplicator. You can freely play around on this staging site. If an error occurs, your main website that is making money is still absolutely safe.
Clone from localhost to hosting to show customers demo
When designing websites for customers, programmers often do it on personal computers quickly, then upload the actual domain name.
Usually, developers often install wordpress on localhost using tools like LocalWP or XAMPP to design first. When the website is complete, clone wordpress from localhost to hosting using Duplicator helps save hours compared to having to import, export the database and reconfigure from scratch.
Back up the entire website periodically for "protection"
Creating a backup of all source code and database is the only way to save your website if it is accidentally attacked by a hacker or has a server error.
backup your wordpress website regularly is a vital principle. You can use the backup wordpress with duplicator feature to download a hard copy to your computer or push it to the cloud. The habit of regularly backing up your wordpress website to protect data backup is also an indispensable part of a comprehensive wordpress website security strategy.
Bloody experience: Common errors when using Duplicator and how to handle them
During use, you may encounter timeout errors due to weak hosts, incorrect database connection errors, or file permission errors on the new server.
Although it is considered very stable, sometimes you will still encounter errors when cloning wordpress with duplicator. Below is how to fix the error based on the actual combat experience of the Pham Hai team as of 2026. If you encounter other problems, you can see more basic how to fix wordpress errors instructions.
Timeout error when creating package (due to weak hosting or too large website)
This error occurs when your server does not have enough resources (RAM, CPU) or the execution time (maxexecutiontime) is too short to compress a large website.
Cách xử lý là bạn hãy vào phần cài đặt của Duplicator, chọn tab Packages và tích vào ô loại bỏ các thư mục nặng như wp-content/uploads hoặc các file backup cũ. Bạn cũng có thể liên hệ nhà cung cấp hosting yêu cầu tăng thông số PHP max_execution_time lên 300 hoặc 600.
Database connection error (usually due to typing wrong name, user, or password)
When running the installer.php file, if it shows red in the Test Database section, 99% of the time the cause is because you entered the wrong database login information.
Hãy kiểm tra lại thật kỹ Tên Database, Username và Password. Lưu ý rằng trên cPanel, tên database thường có thêm tiền tố của user hosting (ví dụ: userhost_tendatabase). Hãy copy paste cẩn thận để tránh dính khoảng trắng ở hai đầu nhé.
Problem with file permissions (File Permissions) on new hosting
After recovering the website, sometimes you cannot upload new images or install additional plugins because the hosting has incorrect permissions for folders.
Để sửa lỗi này, bạn vào File Manager trên hosting, chọn tất cả các thư mục (folders) và set quyền (permissions) là 755. Đối với các tệp tin (files), hãy set quyền là 644. Đây là chuẩn bảo mật chung cho nền tảng WordPress.
Is Duplicator Pro worth the money? Quick comparison with the free version
The free version is enough for small websites, while the Pro version supports direct drag and drop, automatic cloud storage and handles extremely large websites well.
Many people wonder what is better about duplicator pro than the regular version. As of the latest 2026 update, the service plan (Pro) (priced around $69.30/year) offers extremely valuable features. It allows you to automatically backup directly to Google Drive, Dropbox, Amazon S3. In particular, the Pro version supports the exclusive DupArchive compression format, helping to clone huge websites (up to dozens of GB) without ever experiencing timeout errors.

| Drag and drop Import directly | Are not | Have |
| Multisite support | Are not | Have |
Other methods to clone WordPress website
Besides Duplicator, you can use other plugins like All-in-One WP Migration or perform manual migration by copying files via FTP and exporting/importing the database via phpMyAdmin.
There are many ways to clone wordpress to a new domain name. Depending on your preferences and technical skills, you can choose the most suitable option for yourself.
Use another plugin: What's good about All-in-One WP Migration?
All-in-One WP Migration đóng gói toàn bộ website thành một file .wpress duy nhất và cho phép import trực tiếp từ giao diện WordPress.
The strength of All-in-One WP Migration is its extremely intuitive interface, suitable for people who are completely technical. However, the fatal weakness of the free version is its limited import capacity (usually 512MB). If your website is larger, you will have to buy additional extensions which are quite expensive. Meanwhile, the free version of Duplicator is much more generous in terms of capacity.
Doing it manually (FTP & MySQL): For those who like to "dabble" and have a lot of time
Manual migration requires you to manually download the entire wp-content folder, export the database to a .sql file, then upload it to the new host and edit the configuration file yourself.
Cách di chuyển wordpress thủ công này giúp bạn hiểu sâu về cấu trúc của mã nguồn. Bạn sẽ dùng FTP tải file, vào phpMyAdmin để xuất nhập database, và dùng các lệnh SQL để tìm kiếm và thay thế URL cũ thành mới. Cách này an toàn nhưng cực kỳ tốn thời gian và dễ xảy ra lỗi vặt nếu bạn thao tác sai một dấu phẩy trong quá trình cài đặt WordPress lại từ đầu.
