Official docs: Astro Documentation
Adobe's enterprise content management platform. Global enterprises in the Adobe ecosystem needing DAM integration, but these limitations push teams toward modern alternatives.
Most expensive CMS on the market ($250K+/year)
This is the most common reason teams migrate away from Adobe AEM. Astro eliminates this issue entirely.
Requires specialized AEM developers (Java/OSGi expertise)
With Astro, ships zero js to the client by default (islands architecture).
Extremely complex architecture and steep learning curve
Modern architectures like Astro are designed to avoid this from the ground up.
Over-engineered for anything below Fortune 1000 scale
After migrating, you'll no longer need to worry about this — Astro takes a fundamentally different approach.
Content-focused framework that ships zero JavaScript by default. Built with JavaScript/TypeScript (framework-agnostic), it's content-heavy websites that need maximum performance with minimal javascript.
Ships zero JS to the client by default (Islands Architecture)
Use React, Vue, Svelte, or any framework in the same project
Content collections with type-safe Markdown/MDX
Purpose-built for content sites — blogs, docs, marketing pages
Astro is open-source and free to use. You own your code and data with no vendor lock-in. Deploy to any host that supports JavaScript/TypeScript, or use managed platforms like Vercel and Netlify for zero-config deployments.

A detailed breakdown of how your Adobe AEM content maps to Astro
What may need manual attention
Custom server-side logic, third-party integrations, and platform-specific plugins will need equivalent solutions in Astro. The core content (text, images, metadata) transfers cleanly.
Migrate your content in three simple steps
Enter your Adobe AEM site URL — LeaveWP connects automatically.
Select Astro as destination and choose content options.
Download your migrated content or preview it in your browser.
Migrating from Adobe AEM to Astro makes the most sense if you're experiencing most expensive cms on the market ($250k+/year) or outgrowing Adobe AEM's architecture. Astro is best for content-heavy websites that need maximum performance with minimal javascript.
You should migrate if: your Adobe AEM site is slow, your hosting costs are climbing, you need developer flexibility, or you want to adopt a modern JAMstack architecture.
You might want to stay if: your Adobe AEM site benefits from deep integration with the entire adobe creative cloud suite and you don't have JavaScript/TypeScript developers on your team.
The migration itself is straightforward with LeaveWP — enter your Adobe AEM URL, select Astro, and download your content. The more important question is whether Astro's architecture fits your team's skills and your project's long-term needs.
