Hi lovely readers,

If you have been working toward your AZ-204 certification or have been thinking about starting, there is something important you need to know. Microsoft has officially announced that AZ-204: Developing Solutions for Microsoft Azure will retire on July 31, 2026. Its replacement is AI-200: Developing AI Cloud Solutions on Azure, and this is a much bigger change than just a new name.

What is actually changing?

AZ-204 has been the main certification for Azure developers for years. It covers the topics you would expect from a solid Azure developer: App Service, Azure Functions, Cosmos DB, Blob Storage, API Management, and authentication through the Microsoft Identity platform. It is a broad and practical exam, and many developers specializing in Microsoft have this certification or have tried to get it.

AI-200 replaces that entirely. The new exam leads to the Microsoft Certified: Azure AI Cloud Developer Associate credential, and the focus has moved strongly toward building AI-powered applications. Think vector databases, retrieval-augmented generation (RAG), Azure Cosmos DB with semantic search, PostgreSQL with pgvector, Azure Managed Redis for similarity search, and containerized applications on Azure Kubernetes.

This is not a small update. Microsoft is making something very clear here: being an Azure developer in 2026 means knowing how to build with AI, not just around it.

What carries over and what does not?

Around 60% of AZ-204 content carries forward into AI-200. That sounds alright, but it is important to look at what is being removed.

What is gone in AI-200:

• Blob Storage SDK
• Microsoft Identity platform
• Microsoft Graph
• API Management
• Azure Event Hubs
• Azure Queue Storage
• Application Insights SDK (replaced by OpenTelemetry)

If you have been studying those topics, they will not be tested in AI-200.

What is new in AI-200:

• Vector search across Cosmos DB NoSQL, pgvector on PostgreSQL, and Azure Managed Redis
• Kubernetes Event-driven Autoscaling (KEDA) in Container Apps
• Full AKS deployment and management using manifest files
• OpenTelemetry for distributed tracing, instead of the Application Insights SDK
• KQL queries for logs and metrics
• RAG pattern implementation

The difference between the two exams is large enough that you cannot assume your existing study materials for AZ-204 like books or online courses will work for AI-200.

From C# to Python

AZ-204 is designed for developers working in C# or Python. The audience profile mentions Azure SDKs broadly, and the prerequisites name both languages.

AI-200 is different. The official study guide lists Python programming as a required skill, and it is the only language mentioned. If you are a .NET developer who mainly works in C#, that is worth knowing before you start preparing. It does not mean you cannot take the exam, but the exam is written with Python in mind.

Should you still take AZ-204?

It depends on where you are in your preparation.

If you are close to being ready for the exam, taking AZ-204 before July 31st still makes sense. The credential stays valid through its full renewal period even after the exam retires, so you are not losing anything by taking the exam.

If you are just getting started with studying, moving to AI-200 now is the better choice. There is no reason to spend time on topics that will not appear on any future exam. The AZ-204T training course retired on May 29, 2026, and AI-200 training course is now the replacement, so the official learning path has already changed.

If you are starting from scratch: skip AZ-204 entirely and go straight to AI-200.

One thing to keep in mind: the AI-200 exam is currently still in beta. That means practice exams are not available yet, and beta exams are not scored right away while Microsoft collects data on question quality. This might mean that you have to wait for a bit if you prefer to have more practice materials before sitting the actual exam.

A bigger picture

AZ-204 is not the only certification going through this kind of change. Microsoft is retiring several familiar exams this year and replacing them with AI-focused alternatives. AZ-500 is being replaced by SC-500 (Cloud and AI Security Engineer), DP-100 is being replaced by AI-300 (Machine Learning Operations Engineer), and AI-900 was already updated to AI-901 in March 2026.

That's a wrap!
