## Resource

Modernizing legacy systems requires moving beyond simple data migration to creating an AI-ready architecture. This episode explores how MongoDB's Application Modernization Platform (AMP) uses document-first design and vector search to unify operational data with AI context.

## Highlights
- Main idea: AI-readiness requires a unified data layer where operational data, context, and embeddings coexist to prevent latency and drift
- Practical takeaway: Use schema versioning patterns to manage evolution without the need for massive, high-risk data migrations
- Failure mode: Relying on simple versioning (what changed) instead of capturing context (why it changed) will break agentic workflows
- Main idea: Modernization should be approached in 'units'—migrating specific business domains like product catalogs rather than entire estates at once
- Practical takeaway: Leverage a document model to reduce the 'impedance mismatch' between database layers and application APIs

## Topics

Application Modernization, Vector Search, Document Databases, AI Infrastructure, Data Engineering, Schema Design, RAG, Legacy Migration
