Migration and Modernization Design
Migration questions cover Cloud Adoption Framework, discovery, assessment, dependency mapping, Azure Migrate, workload modernization, database migration, and storage migration.
How to study for AZ-305
Treat each AZ-305 item as an architecture decision: identify the workload requirement, governance boundary, data shape, recovery objective, and infrastructure tradeoff before choosing.
Core concepts
Concept 1
Migration and Modernization Design questions test Azure architecture tradeoff decisions rather than isolated service-name recall.
Exam cue: Identify the requirement, workload type, data shape, access boundary, recovery target, and operational ownership model.
Concept 2
The best answer maps business requirements to identity, governance, data, resilience, compute, network, security, cost, and operations constraints.
Exam cue: Choose the Azure design that satisfies the constraint with the least unnecessary operational burden.
Concept 3
Eliminate answers that ignore governance scope, recovery objectives, data durability, private connectivity, security boundaries, or workload fit.
Exam cue: Prefer Well-Architected choices: secure, reliable, cost-aware, observable, governed, and scalable.
Risk pitfalls and guardrails
Choosing a service before identifying the business driver and nonfunctional requirement.
Guardrail: Avoid answers that pick services without checking governance scope, data model, recovery target, migration dependency, or network boundary.
Solving availability while ignoring identity, data protection, compliance, or cost constraints.
Guardrail: Avoid answers that pick services without checking governance scope, data model, recovery target, migration dependency, or network boundary.
Assuming a migration, networking, or storage pattern is correct without checking workload dependencies.
Guardrail: Avoid answers that pick services without checking governance scope, data model, recovery target, migration dependency, or network boundary.
Memory anchors
Cloud Adoption Framework
The Cloud Adoption Framework provides guidance for strategy, planning, readiness, adoption, governance, and management.
Azure Migrate
Azure Migrate assesses and migrates servers, databases, web apps, and virtual desktops to Azure.
Dependency Mapping
Dependency mapping identifies application relationships that affect migration grouping and sequencing.
Rehost
Rehost moves a workload with minimal change, often called lift and shift.
Refactor
Refactor adapts application components to better use cloud services without a full rebuild.
Rearchitect
Rearchitect changes application design to meet cloud scalability, reliability, or agility goals.
Database Migration
Database migration planning matches engine compatibility, downtime tolerance, data size, and target service.
Storage Migration
Storage migration moves file or object data while preserving access, security, and cutover requirements.
Landing Zone Readiness
Landing zone readiness confirms identity, network, governance, security, and operations foundations before migration.
Cutover Plan
A cutover plan defines the sequence, validation, rollback, and communication steps for go-live.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
You must discover on-premises servers, assess Azure readiness, and estimate cost before migrating. Which service fits?
Your design must migrate VMs to Azure with minimal changes to the application (lift-and-shift). Which migration strategy is this?
