Enterprise DXP with advanced personalization. Fortune 500 companies needing omnichannel personalization at scale, but these limitations push teams toward modern alternatives.
Extremely expensive — enterprise-only pricing
This is the most common reason teams migrate away from Sitecore. Astro eliminates this issue entirely.
Long implementation timelines (months to years)
With Astro, ships zero js to the client by default (islands architecture).
Requires certified Sitecore developers (scarce and expensive)
Modern architectures like Astro are designed to avoid this from the ground up.
Complex architecture creates vendor lock-in
After migrating, you'll no longer need to worry about this — Astro takes a fundamentally different approach.

A detailed breakdown of how your Sitecore 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 Sitecore 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 Sitecore to Astro makes the most sense if you're experiencing extremely expensive — enterprise-only pricing or outgrowing Sitecore's architecture. Astro is best for content-heavy websites that need maximum performance with minimal javascript.
You should migrate if: your Sitecore 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 Sitecore site benefits from industry-leading personalization and a/b testing capabilities and you don't have JavaScript/TypeScript developers on your team.
The migration itself is straightforward with LeaveWP — enter your Sitecore 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.
