WordPress to Astro
Flex Solutions is a product engineering studio that runs fixed scope WordPress to Astro migrations for SaaS teams, content heavy startups, and scale-ups. We move the editorial layer, posts, taxonomies, redirects, schema, sitemap, and OG cards, off WordPress and onto Astro, and we trade a stack of forty plugins for a static site that ships in milliseconds. Your content team keeps editing. The old stack disappears.
Can You Migrate Without Touching Your Live Site First?
Yes, and this is the part most SaaS product engineering companies skip. You don’t have to sign a 12-week retainer to find out what’s actually broken. A two-week systems audit comes first: two senior engineers read your codebase, interview your team, and trace the system you’re worried about under real production data. Whether or not you move into an embedded quarter afterward, you keep the findings doc.
How Our WordPress to Astro Migration Service Works
- 01
Audit & URL map
We crawl the live WordPress site, inventory every URL, every plugin, every author quirk. You get a one-page audit and a signed-off 301 map. Nothing else moves until that's green.
Crawl reportURL mapPlugin inventoryWEEK 1 - 02
Content export
A reproducible export script pulls posts, ACF fields, custom post types, and media into Markdown. Editors review the diff against a staging environment, and we re-run the export until that diff is empty.

Astro build
We build templates, layouts, islands, search, schema, and OG cards directly against the migrated content from day one, with no placeholder text standing in for real pages.

Cut-over + monitor
DNS switches over on a scheduled day. We watch Google Search Console and analytics for two weeks to confirm nothing regresses, and we train your editorial team on the new workflow before handing off.

What You Get When We Migrate WordPress to Astro
Most WordPress sites are 70% editorial pages, 30% scaffolding, and 100% slow. We move the editorial — posts, taxonomies, redirects, schema, sitemap, OG cards, the whole crawl surface — to Astro. Same URLs, same author flow, none of the plugins.
Full-content migration: posts, pages, taxonomies, ACF fields, custom post types.
Every URL preserved. 301 map signed off by your SEO lead before cut-over.
An Astro static build using islands only where interactivity actually earns its JavaScript.
An editorial workflow on Decap, Sanity, or plain Markdown, whichever your team prefers.
A Lighthouse 100/100/100/100 performance budget enforced on the top 50 pages by traffic.
Cut-over runbook and a rollback path that takes 60 seconds.
Capabilities - Inside Our Astro Migration Service
- 01
Content extraction
WordPress REST API and custom SQL exporters pull posts, pages, ACF fields, custom post types, taxonomies, and media, and serialize all of it to Markdown with front matter. Deterministic and re-runnable, so nothing gets migrated by hand.
- 02
URL & redirect map
A one to one URL map gets signed off before any code ships. Every legacy permalink resolves, and every redirect chain collapses to a single hop.
- 03
SEO continuity
Schema.org JSON-LD, Open Graph tags, sitemap, robots.txt, canonical tags, and hreflang all carry over. We diff the new build against the live site weekly through cut-over.
- 04
Editorial UX
Decap CMS fits solo editors and costs nothing to run. Sanity fits editorial teams needing structured content and roles. Plain Markdown with GitHub pull requests fits engineering led teams.
- 05
Forms & comments
Forms move to Cloudflare Workers or Resend. Comments move to Giscus or Cusdis. No PHP runtime, no spam queue to moderate.
- 06
Edge & search
Sites deploy to Cloudflare Pages or Vercel. Site search runs on Pagefind or Algolia depending on catalog size. See our AI-accelerated delivery service if you want automated content tagging or search built on top once the migration ships.
The ToolChain We Use to Migrate WordPress to Astro
Tested on sites with 40 to 8,000 posts. The bigger the archive, the more these tools earn their keep.

WordPress to Astro Migration vs. the Alternatives
| Comparison factor | Flex Solutions Migration | Hiring a Front-End Engineer | Staying on WordPress and Optimizing |
|---|---|---|---|
| Time to start | 1 week audit, embedded from day one | Weeks to months of hiring and ramp-up | Immediate, but ceiling is low |
| Cost structure | Fixed scope, quarterly | Salary, equity, benefits, indefinitely | Ongoing plugin, hosting, and maintenance fees |
| Risk if the fit is wrong | Audit ends at zero cost before build starts | A bad hire costs months to unwind | Sunk cost keeps compounding |
| Best fit | Content heavy sites ready to leave plugin architecture behind | Teams that need a permanent in-house owner | Teams not yet ready to leave WordPress at all |

Numbers from Our Astro Migration Service Engagements
Not if the redirect map and content diff are done correctly. Every legacy URL gets a signed off 301 redirect before cut-over, and the team monitors Search Console and analytics for two weeks after launch to catch any drop early.
Yes. The audit and URL map happen against the live site with no code changes to it. Cut-over is a scheduled DNS swap, not a rebuild-in-place, so the live site keeps serving traffic right up until the switch.
Wherever fits your team. Decap CMS suits solo editors and is free to run, Sanity suits editorial teams that need structured fields and permissions, and plain Markdown with GitHub pull requests suits engineering led teams that already work in a repo.
Form functionality moves to Cloudflare Workers or Resend instead of a PHP plugin, so submissions still reach your inbox or CRM without a WordPress backend running behind the scenes.
Scope for a WooCommerce or other e-commerce migration is assessed case by case during the audit, since checkout, inventory, and payment logic need their own migration plan separate from editorial content.
A standard engagement runs four to eight weeks from audit to cut-over. Larger archives, heavier custom plugin logic, or e-commerce functionality extend that timeline, which is why the exact schedule gets set after the Week 1 audit, not before it.
