10We migrated our blog to Val Town 🥳
79## A fast migration
80
81How did we migrate 65 blog posts – with images, videos, and intricate formatting and styles – to an entirely new blog in a single day?
82
83We didn't. We left them where they are, and proxy to them.

30  - **`proxy.ts`**: Proxy to the old blog for legacy content
31  - **`rss.ts`**: RSS feed generation
32  - **`favicon.ts`** & **`og-image.ts`**: Asset routes
33- **`/utils/`**: Utility functions for post processing, caching, etc.
34- **`/posts/`**: Markdown files for blog posts
69- Tables
70- Lists
71- Images
72- And other standard markdown features
73
91- Efficient proxy for legacy content
92- Minimal CSS with no external frameworks
93- Optimized image handling
94
95## Deployment
