Migrations from RDBMS to Cosmos DB are notorious for hard decisions — denormalization tradeoffs, partition key selection, embedded vs. referenced data, and complex application code conversion.

What if an AI agent could analyze your schema, generate a migration plan, provision Cosmos DB infrastructure, rewrite your data layer to the Cosmos SDK, and migrate your data — all through natural-language prompts?

Sergiy Smyrnov (Principal PM, Azure Cosmos DB) takes the classic AdventureWorks database and an old ASP.NET EF Core app and live-walks every step: from relational schema to a fully running .NET 9 app backed by Cosmos DB for NoSQL.

You'll leave with a reusable, prompt-by-prompt playbook and learn how to use Cosmos DB Agent Kit AI skills for your own migrations.
