It’s 2024, and to no one’s surprise, the competitive landscape is dictated by digital transformation. Consequently, migrating to a cloud platform like Microsoft Azure has become more than a strategic move and is now a necessity for businesses aiming for agility, scalability, and cost-effective business continuity. However, the path to Azure migration has its fair share of complexities. Improper planning and execution can lead to extended timelines and disrupt business continuity. Additionally, you can expect a hefty increase in your monthly IT spend if careful consideration is not made when scoping and building resources within Azure.
Agile IT can help you avoid these pitfalls and successfully plan your Azure migration from a 2024 perspective. Below, we offer a detailed roadmap for businesses looking to leverage the cloud for enhanced performance and growth by planning their migration effectively.

Key Phases in Azure Migration Planning
Before looking at the key phases in migration planning, businesses need to assess the type of migration they want. These are:
- Lift-and-shift migration: Lift-and-shift migrations are typically chosen for one of two reasons: there is a time constraint (end-of-life for on-premises hardware, or contractual considerations, perhaps), or because applications and systems can be moved easily, with no need for re-architecting the deployment/configuration. With time-constrained Azure migrations, organizations may find it prudent to move the environment as-is to Azure, and re-architect and modernize post-migration. For a “simple” migration, the existing on-premises applications and data can be transferred to Azure with little to no modifications. For example, the migration of SQL Server databases to Azure SQL Database or Azure SQL Managed Instance.
- Complex migration: Involves more complicated scenarios centered on re-architecting applications for the cloud. This type of migration also includes adding compliance and security, managing data transfer, and optimizing costs. For instance, moving an existing financial services application from an on-premises data center to Azure requires a redesign of the application’s data handling and processing architecture to function optimally in a cloud-native environment.
Based on these scenarios, you can determine the type of migration that will serve you best. For either scenario, Microsoft suggests a structured four-step migration process designed to streamline the transition and minimize disruption. These steps consist of discovery, assessment, targeting, and migration. Let’s dig in. These steps consist of discovery, assessment, targeting, and migration. Let’s dig in.
Discover: Cataloging Your Software and Workloads
The discovery phase is the foundation of the migration process. During this stage, organizations must take inventory of their existing IT infrastructure, software, and workloads. This involves identifying all the components in the current environment, including servers, storage systems, applications, databases, and network configurations. The goal is to create a comprehensive catalog of resources, dependencies, and performance metrics.
This stage is critical because it lays the groundwork for the entire migration process. A thorough discovery helps organizations understand the scope and complexity of their existing IT landscape. Tools like Azure Migrate (free from Microsoft, included with your Azure subscription), can automate much of this process.
How? By providing insights into the environment and identifying dependencies between applications and workloads. Understanding what resources are used and how they interact can help organizations move towards Azure migration planning, which ultimately minimizes downtime and performance impacts.
Assess: Categorizing Applications and Workloads
With a detailed inventory in hand, the next step is to assess these applications and workloads. This involves evaluating each item in the catalog. You must do this to determine its importance, complexity, and suitability for migration to Azure. Factors such as compatibility with Azure services, potential migration challenges, and the strategic value of each application are considered in this stage of Azure migration planning. It is all about prioritizing and categorizing workloads based on various criteria, including:
- Criticality: How vital is the application to business operations?
- Complexity: What are the technical challenges associated with migrating this application?
- Dependency: Does the application have dependencies that could complicate migration?
- Compliance and Security: Are there regulatory or security considerations that need to be addressed?
The assessment phase helps organizations understand which applications:
- Can be migrated easily
- May require significant refactoring
- Should perhaps remain on-premises or be retired
Tools like the Azure Migrate service offer insights into compatibility issues and provide guidance on remediation steps.
Target: Identifying the Destinations for Each of Your Workloads
Once applications and workloads have been cataloged and assessed, the next step is to identify the most appropriate Azure destination for each. This involves deciding whether to use Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS) offerings for different workloads. Key considerations in this stage include:
- Performance Requirements: Matching the performance characteristics of Azure services with the needs of each workload.
- Cost Management: Understanding the cost implications of different Azure services and selecting options that provide the best value.
- Compliance and Security: Ensuring that the chosen Azure services meet the necessary compliance and security standards.
This phase is about mapping out where each piece of the IT puzzle will fit in the Azure ecosystem. It’s a critical step for aligning the technical aspects of the migration with business objectives and requirements.
Migrate: Making the Actual Move
The final step in the migration process is the actual move to Azure. This involves the migration of data, applications, and workloads to Azure services. Depending on the complexity and requirements of each workload, this could involve simple rehosting (often referred to as “lift and shift”), refactoring applications to better align with cloud-native services, or a complete rebuild in Azure.
The migration phase can be a complex and time-consuming process involving:
- Preparation: Ensuring that all prerequisites for migration are met, which includes network configurations, security settings, and compliance checks. This is where you “double-check” your discovery and assessment phases.
- Execution: The movement of applications and data to Azure, which can be done using tools like Azure Site Recovery for virtual machines or Azure Database Migration Service for databases. Execution is often a cut-over event, with the goal of minimal downtime or disruption to business processes.
- Execution: The movement of applications and data to Azure, which can be done using tools like Azure Site Recovery for virtual machines or Azure Database Migration Service for databases. Execution is often a cut-over event, with the goal of minimal downtime or disruption to business processes.
- Validation: Thorough testing for performance, security validation, and user acceptance, which is essential to ensure that applications function correctly in their new environment.
The migration phase is not just about moving resources; it’s about ensuring they operate efficiently and securely in their new cloud environment. In any Azure migration, planning, preparation, execution, and validation are key steps to minimize downtime and ensure business continuity.
