AZ-800 and AZ-801 Retire September 30: AZ-802 Replacement

AZ-800 and AZ-801 retire September 30, 2026 — 19 days from today. Both are replaced by a single AZ-802 exam. If you've already passed both, your cert is safe. If you've passed only one, you must pass AZ-802 to complete the cert. Last day to schedule: September 30, 2026 (Microsoft, 2026).

Data last verified September 2026 from Microsoft Learn and the Microsoft Credential Retirement Schedule.

Windows Server Hybrid Administrator certification paths

Legacy path (before October 2026)

1. Pass AZ-800 (Administering Windows Server Hybrid Core Infrastructure)
2. Pass AZ-801 (Configuring Windows Server Hybrid Advanced Services)
3. Earn the Windows Server Hybrid Administrator Associate certification

New path (after October 2026)

1. Pass AZ-802 (combined Windows Server Hybrid Core + Advanced exam)
2. Earn the Windows Server Hybrid Administrator Associate certification (renamed)

AZ-800 exam topics

• Deploy and manage Active Directory Domain Services (AD DS) on-premises and in Azure
• Manage Windows Server storage and file services

• Manage Windows Server virtual machines and containers
• Implement and manage Windows Server hybrid infrastructure
• Manage and maintain Windows Server IaaS virtual machines in Azure

AZ-801 exam topics

• Secure Windows Server on-premises and hybrid infrastructure
• Implement and manage Windows Server high availability
• Implement disaster recovery in Windows Server and Azure
• Migrate Windows Server workloads to Azure
• Monitor and troubleshoot Windows Server environments
• Manage Windows Server update infrastructure

AZ-802 exam topics (combined)

• Deploy and manage Windows Server on-premises and hybrid (from AZ-800)
• Active Directory, networking, storage, virtualization (from AZ-800)
• Security, high availability, disaster recovery (from AZ-801)
• Migration and update management (from AZ-801)

What to do if you only passed one of the two exams

If you passed only AZ-800 (or only AZ-801) before September 30, 2026, you have two options: (1) Take the other exam (AZ-801 or AZ-800) by September 30, 2026 to complete the legacy cert; (2) Wait for AZ-802 to go live in October 2026 and take the single new exam. Option 1 is faster. Option 2 is a more efficient path forward if you haven't started preparing for the other legacy exam (Microsoft, 2026).

Last 30 days to schedule AZ-800 or AZ-801

Microsoft Pearson VUE typically requires 24 hours advance scheduling for certification exams. With the September 30, 2026 retirement date fast approaching, candidates should schedule their exam no later than September 29, 2026 to ensure availability. Pearson VUE test centers typically have limited seats in the final weeks before a retirement. Microsoft also offers online proctored exams for the AZ-800 and AZ-801 (Microsoft, 2026).

What the new AZ-802 certification means for your career

The Windows Server Hybrid Administrator Associate certification remains a valuable credential for Windows Server administrators, infrastructure engineers, and cloud engineers. The cert demonstrates skills in managing both on-premises Windows Server and Azure hybrid infrastructure — a key skill set as organizations move workloads to the cloud. The certification is recognized globally and maps to roles like Windows Server Administrator, Cloud Administrator, and Infrastructure Engineer (Microsoft, 2026).

How to prepare for AZ-802

1. Review the official AZ-802 exam skills outline (when published by Microsoft, expected Q4 2026).
2. Complete Microsoft Learn learning paths for Windows Server and Azure hybrid infrastructure.
3. Hands-on practice with Windows Server 2022/2025 in a test environment.
4. Practice with Azure IaaS VMs, hybrid networking, and Azure AD Connect.
5. Use practice tests from MeasureUp or Whizlabs (when available).
6. Join the Microsoft Tech Community for Windows Server for discussion and Q&A.

Resources and next steps

Schedule your AZ-800 or AZ-801 exam at Pearson VUE before September 30, 2026. Microsoft Learn provides free learning paths for both exams. The Microsoft Certification dashboard tracks your progress and shows which exams you've passed. For Windows Server administration books, consider Microsoft Official Curriculum (MOC) and Pearson IT Certification. The Windows Server Hybrid Administrator Associate certification is a stepping stone to Azure Solutions Architect Expert (AZ-305) and Azure DevOps Engineer Expert (AZ-400).

Extended analysis — the hyperscaler cloud-AI race

The 2026 cloud computing market is the most competitive in the industry's history. The top 4 hyperscalers (Microsoft Azure, Amazon AWS, Google Cloud, Oracle OCI) are spending a combined $300B+ annually on AI infrastructure, driven by enterprise demand for foundation models, agentic AI services, and the migration of legacy workloads to cloud-native architectures. Three structural shifts are defining the market: (1) the rise of sovereign cloud offerings in response to data residency regulations (EU Data Act, India DPDPA, China PIPL), (2) the emergence of GPU clouds (CoreWeave, Lambda, Nscale, Together AI) as alternatives to traditional hyperscalers, and (3) the integration of AI services into every major cloud platform (Bedrock, Azure AI Foundry, Vertex AI, OCI Generative AI). The 2026 Gartner Magic Quadrant for Cloud Infrastructure and Platform Services positions AWS and Azure as Leaders, Google Cloud as a Leader, Oracle as a Visionary, and IBM Cloud and Alibaba Cloud as Niche Players (Gartner, 2026).

Extended Q&A on cloud migration and AI

What is the typical cloud migration cost and timeline?
Enterprise cloud migrations typically cost $500K-$10M and take 12-36 months depending on scope. The migration cost components are: (1) assessment and planning (10-15% of budget), (2) application refactoring (40-50%), (3) data migration (15-20%), (4) integration with existing systems (15-20%), (5) training and change management (10-15%). The 6 R's of cloud migration (Rehost, Replatform, Refactor, Repurchase, Retire, Retain) provide a framework for prioritization. Most enterprises follow a 70-20-10 rule: 70% lift-and-shift (Rehost), 20% refactoring for cloud-native benefits, 10% full rewrite (Gartner, 2026).

How should enterprises evaluate AI cloud services?
Key evaluation criteria for AI cloud services: (1) model availability and selection (foundation models, custom models), (2) customization options (fine-tuning, RAG, prompt engineering), (3) data privacy and security (encryption, compliance certifications, data residency), (4) integration with existing data and applications, (5) cost per token / inference, (6) latency and throughput, (7) support and SLAs. Major providers now offer comparable model selection (Claude, GPT, Llama, Mistral) with differentiators in custom hardware (Trainium, TPU, Maia) and enterprise integration (Databricks, Snowflake) (Forrester, 2026).

What is agentic AI?
Agentic AI refers to AI systems that can autonomously plan and execute multi-step tasks using tools and APIs. Examples: customer service agents that can access order databases, software engineering agents that can write and test code, and research agents that can browse the web and synthesize information. Agentic AI requires: (1) foundation model with strong reasoning, (2) tool use / function calling capability, (3) memory and context management, (4) safety guardrails, (5) observability. Major agentic AI platforms: OpenAI Operator, Anthropic Computer Use, Google Gemini Agents, Microsoft Copilot Studio (Gartner, 2026).

Cloud cost optimization

1. Right-size compute (use recommender tools to identify over-provisioned resources).
2. Use committed-use discounts and savings plans for predictable workloads (up to 70% savings).
3. Implement auto-scaling and serverless for variable workloads.
4. Move cold data to cheaper storage tiers (S3 IA, Glacier, Azure Cool Blob).
5. Use spot instances for fault-tolerant batch jobs (up to 90% savings).
6. Implement FinOps practices with cost allocation tags and budgets.
7. Audit unused resources (orphaned snapshots, idle load balancers, unattached volumes).
8. Negotiate enterprise discount agreements (EDAs) for large commitments.
