如何迁移WordPress 2026

Migrating a WordPress site to a new host is one of the most common maintenance tasks. and one of the most feared. Done correctly, you can move an entire WordPress installation (database, files, themes, plugins, and media) to a new host with zero downtime. Done carelessly, you risk data loss, broken links, or days of debugging. This guide walks through both the plugin method (fastest) and the manual method (most control).

我们如何核对文中步骤

发布前，若步骤依赖主机商，我们会在至少两家平台各走一遍；否则在同一环境隔日执行两次。我们记录控制台报错、不同地区的界面文案差异，并在厂商调整按钮位置后立即更新文案。路径与截图每季度抽检。涉及 DNS、SSL 或付款时，我们确认回滚/补救选项，并链接到官方文档以获取权威表述。

  1. 1

    Step 1: Choose your new host and set up the account

    Before migrating, ensure your new host is configured with PHP 8.2+ and MySQL/MariaDB. Create your hosting account, set up a database (note the name, username, and password), and confirm your new host's server address. SiteGround, Hostinger, and WP Engine all offer free migration services. Check if your new host will do it for you.

  2. 2

    Step 2: Back up your entire WordPress site

    Never migrate without a fresh backup. Use UpdraftPlus, Duplicator, or All-in-One WP Migration to create a complete backup of your files and database. Store the backup on your computer or cloud storage. not just on the same server you're moving away from. This backup also serves as your migration package.

  3. 3

    Step 3: Export your database

    If migrating manually: log in to your current host's phpMyAdmin, select your WordPress database, and click Export. Choose "Quick" export method and SQL format. Download the .sql file. If using a migration plugin (Duplicator or All-in-One WP Migration), this is handled automatically as part of the backup package.

  4. 4

    Step 4: Transfer WordPress files to the new host

    For manual migration: use FTP/SFTP (FileZilla is free and excellent) to upload all WordPress files to your new host's public_html directory. This includes the wp-content folder (themes, plugins, uploads) and all core WordPress files. For plugin migration: install the migration plugin on your new host and import the backup package from Step 2.

  5. 5

    Step 5: Import the database to the new host

    Log in to your new host's phpMyAdmin, select the empty database you created, and click Import. Upload the .sql file from Step 3. After import, update the wp_options table: change siteurl and home values to your domain (or temporary staging URL if testing first).

  6. 6

    Step 6: Update wp-config.php

    Edit the wp-config.php file on the new server to update the database connection details (DB_NAME, DB_USER, DB_PASSWORD, DB_HOST) to match your new database credentials. If testing on a temporary staging URL, also update the site URL constants if they were hardcoded.

  7. 7

    Step 7: Test on a staging URL before switching DNS

    Before pointing your live domain to the new host, test by temporarily editing your computer's hosts file to preview the new site. Alternatively, use a temporary staging URL if your new host provides one (SiteGround and WP Engine both do). Check all pages, forms, and checkout (if WooCommerce) work correctly.

  8. 8

    Step 8: Point your domain to the new host

    Update your domain's nameservers (at your domain registrar) to your new host's nameservers. DNS propagation takes 1–48 hours globally. During this time, some visitors may see the old site and some the new. Your old host's site remains live during propagation, so no data loss occurs if both are in sync.

常见问题

Will my WordPress site go down during migration?+
Not if you follow the staging approach. Set up the new host, test thoroughly, then switch DNS. Your old site remains live throughout, so visitors experience minimal to zero downtime. The only potential gap is during DNS propagation (0–48 hours).
How long does WordPress migration take?+
For a typical 5–10 GB site: 1–3 hours for the full manual process, or 30–60 minutes using a migration plugin. Large WooCommerce stores or sites with gigabytes of media uploads take longer.
Do I need a migration plugin or can I do it manually?+
Both methods work. Migration plugins (Duplicator, All-in-One WP Migration) are faster and less error-prone for most users. Manual migration gives more control and is better for complex configurations or when the plugin has size limitations.
Will my site's SEO be affected by migration?+
Not if you preserve your URL structure and set up 301 redirects for any changed URLs. Use a permalink structure check after migration. If your domain name is unchanged, Google will continue to index your site normally after it discovers the new server location.
