What WordPress Multisite Migration Actually Requires — And Why Most Agencies Won't Touch It

Your WordPress Multisite network runs 30+ subsites off one database, one plugin stack, one shared wp_users table. A migration pulls each subsite out — extracting content from prefixed tables like wp_2_posts and wp_3_options, remapping user capabilities stored as serialized arrays, rewriting every hardcoded media URL from /sites/[site-id]/ directories, and rebuilding the whole thing as isolated Next.js routes with per-location Supabase queries. Your team gets separate content stores, independent authentication, and zero shared plugin vulnerabilities. The old network had one entry point for attackers. Your new stack has none.

專案失敗的原因

One plugin vulnerability on one subsite exposes all 30+ sites simultaneously That's not a hypothetical — 96% of WordPress exploits target plugins, and your entire network shares one attack surface. All it takes is one unpatched plugin on one subsite.
Prefixed database tables (wp_2_posts, wp_3_options) turn what should be a straightforward extraction into a multi-day operation Serialized data makes it worse — it contains hardcoded domain references, so a naive find-and-replace doesn't just miss things, it actively corrupts widget configs and option values.
The shared wp_users table with per-site capabilities (wp_2_capabilities, wp_3_capabilities) is its own headache You can't cleanly separate user access without remapping every capability key per subsite. There's no clean path — just careful, tedious work.
Media files live in /wp-content/uploads/sites/[site-id]/ with hardcoded URLs baked into the content itself Move or restructure any subsite and you break every image and file reference in that subsite overnight.
Domain-mapped subsites each need individual DNS changes, SSL certificates, and redirect rules Miss one domain during migration and you've handed that subsite's indexed pages and organic traffic to a 404 page.
Then there's the plugin problem The plugin that runs fine on your main site breaks on subsite #7 — and you can't update them independently. Network-activated plugins force every subsite onto the same version, so each update is a network-wide gamble.

Prefixed Table Extraction

We remap every wp_N_ prefixed table to clean schema structures in Supabase. Serialized data gets parsed properly — domain references rewritten without touching the serialization format itself.

Multi-Tenant Row-Level Security

Each former subsite gets its own location_id in Supabase, with RLS policies enforcing content isolation. No shared database, no cross-site data leaks. They're genuinely separate now.

Per-Site User Role Mapping

We extract per-subsite capabilities from the shared wp_users table and remap them to Supabase Auth roles. Each user ends up with the right permissions per location — a single login that actually knows where they're allowed to be.

Media URL Rewriting

Every media file from /wp-content/uploads/sites/[id]/ moves to CDN-optimized storage, and all content references get rewritten to the new paths with next/image optimization baked in.

Per-Domain Redirect Mapping

Every URL across every subsite — including domain-mapped custom domains — gets a 301 redirect to its new path. No orphaned URLs, no rankings quietly disappearing in the background.

Network-Wide Performance Audit

We benchmark each subsite's Core Web Vitals, page count, and plugin dependencies before migration starts. After launch, we verify 95+ Lighthouse scores across all locations. You get before-and-after numbers, not just a promise.

我們構建的內容

One plugin exploit hits all 30+ subsites simultaneously because network activation forces identical versions everywhere

Automated REST API extraction pulls posts, taxonomies, ACF fields, and meta from each subsite without manual exports

Prefixed database tables scatter your content across wp_2_posts, wp_3_options, wp_7_postmeta with no clean export path

Dynamic /locations/[slug] routes share brand components while serving isolated content from Supabase per-location queries

Shared wp_users table stores per-site capabilities as serialized keys that break on naive migration attempts

Normalized schema replaces wp_N_ prefix chaos with location_id foreign keys and actual relational structure

Media files live in /sites/[site-id]/ with hardcoded URLs baked into post content and widget configs

Custom admin interface manages content and users per location without WordPress core or plugin conflict risk

Domain-mapped subsites each require separate DNS, SSL, and redirect coordination or you lose indexed traffic overnight

Pre-rendered pages serve static HTML from edge nodes with zero PHP execution or database queries on page load

Network-wide plugin updates gamble every subsite's stability because you can't update subsites independently

Per-domain GSC properties and sitemap monitoring track indexing stabilization across every former subsite domain

我們的流程

01

Network Audit

Start by mapping every subsite: URLs, content volume, active plugins, custom post types, domain mapping configuration, and user role distribution. You need to know exactly what shared functionality exists versus what's site-specific, and you need to flag every piece of serialized data that contains domain references before anything moves.
Week 1-2
02

Architecture Design

Then design the Next.js route structure, Supabase schema with location_id and RLS policies, shared component library, and per-location content models. The redirect strategy for every domain gets defined here too — before a single line of migration code runs.
Week 2-3
03

Content Export & Media Migration

Extract content via the WP REST API per subsite. Download media from each /sites/[id]/ directory. Export users with per-site capability mapping. Validate serialized data integrity at every step.
Week 3-5
04

Build & Import

Build the Next.js multi-tenant application with Supabase Auth, RLS, and the admin dashboard. Then batch import all content, rewrite all media URLs, and map users to Supabase Auth with the correct per-location roles assigned.
Week 5-10
05

Redirect Mapping & Launch

Implement 301 redirects for every URL across all subsites and domain-mapped domains. DNS cutover per domain. GSC property updates. Monitor indexing across all former subsites for 30 days post-launch — long enough to catch anything that wants to surface late.

常見問題

為什麼 WordPress Multisite 遷移比單網站遷移更難？

以下是 Multisite 遷移真正複雜的原因：每個子網站有自己帶前綴的資料庫表格（wp_2_posts、wp_3_options），但所有人共享一個 wp_users 表格，其中每個網站的功能都被烘焙在內。媒體位於單獨的 /sites/[id]/ 目錄中。序列化資料在整個過程中散落著域特定的參考。提取一個子網站意味著重新對應所有帶前綴的表格、重寫序列化資料而不損壞、遷移媒體路徑以及處理每個域的 DNS——然後對網絡中的每個子網站再做一遍。

您能否遷移具有自訂域的子網站？

對於域映射的子網站，我們按域處理 DNS 切換、SSL 憑證配置和 301 重定向實現到其新的路徑結構。每個自訂域獲得自己的 Google Search Console 屬性更新和專用索引監控。我們協調各個域的切換時間，以最大限度地減少所有域的停機時間——在有意義的地方錯開，在沒有意義的地方進行批處理。

跨子網站的共享用戶會發生什麼？

WordPress Multisite 將所有用戶存儲在一個 wp_users 表格中，具有每個網站的功能，例如 wp_2_capabilities 和 wp_3_capabilities。我們提取每個用戶的每個網站角色，將其對應到 Supabase Auth，並使用行級安全性分配位置特定的權限。最終結果：具有每個位置的正確訪問級別的單一登錄，無需任何人查看他們不應該看到的內容。

遷移過程中我們會失去 SEO 排名嗎？

我們為所有子網站上的每個 URL 構建 301 重定向對應，包括域映射的自訂域。Google Search Console 屬性按域設置，並在啟動日期提交更新的網站地圖。我們在啟動後 30 天內監控所有前子網站的索引，以捕捉任何漏掉的東西。值得注意的是：從靜態 HTML 的性能提升通常有利於排名，而不是傷害排名。

WordPress Multisite 遷移需要多長時間？

時間表根據網絡大小而定。5–10 個子網站的網絡通常需要 8–10 週。25–50 個子網站範圍的網絡運行 12–16 週。擁有 50+ 個子網站、複雜域映射和自訂功能的企業網絡可能需要 16–24 週。審計階段確定了您特定網絡的準確時間表——上面的數字是起點，不是保證。

從 WordPress Multisite 遷移後的安全改進是什麼？

WordPress Multisite 網絡是高價值目標，恰恰是因為一個外掛漏洞會同時影響每個子網站。遷移後，您的網站是從 CDN 提供的預渲染靜態 HTML——沒有 PHP 執行時，沒有暴露於網絡的資料庫，沒有外掛漏洞可以抓住的東西。攻擊面降至基本為零。不再有凌晨 2 點的 Wordfence 警報。不再有緊急修補。不再每次外掛更新時屏住呼吸。
