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.

项目失败的原因

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.

我们构建的内容

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

我们的流程

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.

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.

常见问题

为什么 WordPress Multisite 迁移比单站点迁移更复杂？

以下是使 Multisite 迁移真正复杂的原因：每个子站点都有自己带前缀的数据库表（wp_2_posts、wp_3_options），但每个人共享一个 wp_users 表，其中每站点功能已内置。媒体存储在单独的 /sites/[id]/ 目录中。序列化数据在整个地方都散布着特定于域的引用。提取一个子站点意味着重新映射所有带前缀的表、重写序列化数据而不损坏、迁移媒体路径和处理每域 DNS — 然后对网络中的每个子站点再做一遍。

您能迁移具有自定义域的子站点吗？

对于域映射的子站点，我们按域处理 DNS 切换、SSL 证书配置和 301 重定向实现从旧域到其新路径结构。每个自定义域都获得自己的 Google Search Console 属性更新和专用索引监控。我们协调切换时间以最小化所有域中的停机时间 — 在有意义的地方交错进行，在不必要的地方批量进行。

跨子站点的共享用户会发生什么？

WordPress Multisite 将所有用户存储在一个 wp_users 表中，具有每站点功能如 wp_2_capabilities 和 wp_3_capabilities。我们提取每个用户的每站点角色，将其映射到 Supabase Auth，并使用行级安全性分配特定于位置的权限。最终结果：单一登录，每个位置都有正确的访问级别，没有任何人看到他们不应该看到的内容。

迁移过程中我们会失去 SEO 排名吗？

我们为所有子站点中的每个 URL 构建 301 重定向映射，包括域映射的自定义域。Google Search Console 属性按域设置，更新的站点地图在启动日提交。我们在启动后 30 天内监控所有前子站点的索引，以捕获任何遗漏的内容。值得注意的是：从静态 HTML 的性能提升通常有助于排名而不是伤害排名。

WordPress Multisite 迁移需要多长时间？

时间线按网络规模扩展。5–10 个子站点的网络通常需要 8–10 周。25–50 个子站点范围的网络运行 12–16 周。拥有 50 个以上子站点、复杂域映射和自定义功能的企业网络可能需要 16–24 周。审计阶段确定了您特定网络的准确时间线 — 上述数字是起点，不是保证。

从 WordPress Multisite 迁移后的安全性改进是什么？

WordPress Multisite 网络是高价值目标，恰恰是因为一个插件漏洞会同时影响每个子站点。迁移后，您的站点是从 CDN 提供的预渲染静态 HTML — 没有 PHP 运行时、没有数据库暴露于网络、没有插件漏洞可以抓取的东西。攻击面本质上降至零。不再有凌晨 2 点的 Wordfence 警报。不再有紧急补丁。每次插件更新发布时不再屏住呼吸。
