How to migrate and modernise
Learn how to move your apps, data and infrastructure to Azure using a proven cloud migration and modernisation approach. Plus, find cloud migration and modernisation planning tools and guidance to help you accelerate your journey and move with confidence.
The stages of your migration and modernisation journey
Cloud migration and modernisation is a continuous process that involves significant organisational change management spanning people, process and technology. Taking a holistic approach will not only help you navigate the journey successfully but also help ensure that your organisation realises new benefits—including efficiency, agility and scale—once your workloads are running in the cloud.
Define your strategy, align stakeholders and assess environments.
Define your strategy
Define and document your motivations
Define why you are migrating and modernising. Document the business outcomes that you want to achieve and your motivations, such as exiting your datacentre, increasing cost saving or designing for greater agility.
Involve and align key stakeholders
Facilitate a smoother, faster migration that meets organisational goals by enlisting the broad support. Create a centre of excellence with a cross-functional team made up of IT, finance and business owners.
Engage a cloud migration and modernisation partner
Augment your cloud skillset and reduce risk as you migrate and modernise your workloads. Team up with a managed service provider that offers support through the entire process and beyond.
Plan for your move
Discover and assess your apps, databases and infrastructure.
Get insights into your dependencies using automated cloud migration tools. Inventory your infrastructure and assess your on-premises environments—get right-sizing guidance, workload-level cost estimates and performance metrics.
Make a business case for migration and modernisation
Evaluate the potential cost savings of migrating to Azure by calculating and comparing your total cost of ownership (TCO) for Azure with that of a comparable on-premises deployment.
Build a holistic plan
Account for workload priorities, timelines, milestones, resources and funding. Then break up your overall plan into migration and modernisation projects, each with a group of related workloads. Get buy-in from leadership and your new migration center of excellence.

Financial considerations for cloud migration
Building landing zones for successful migration
Build landing zones—then migrate and modernise in waves.
Get ready for the move
Build cloud skills
Get your IT and app development teams up to speed on cloud technologies, migration tools and operational processes. Upfront training investment helps you to scale your migration efforts more efficiently and set up your organisation for success.
Set up landing zones for your workloads
Help avoid governance issues during and after migration by using landing zone best practices. Preconfigured landing zones include networking, identity, management, security and governance elements that balance agility with organisational standards.
Review best practices for Azure readiness
Help ensure the proper configuration of your current and future landing zones by expanding and validating landing zone modifications with Azure readiness best practices.
Migrate your workloads
Make cloud migration easier with centralised tools
Discover, assess and migrate your workloads with a comprehensive resource like Azure Migrate—the central hub for all of your migration automation needs. Find all of the tools and guidance you need to implement your move—and track your progress from a central dashboard.
Assess, migrate, optimise and promote workloads iteratively
Use an iterative process of migrating one workload at a time or a small collection of workloads per release. Help ensure that workloads are ready to meet production demands by assessing, migrating, optimising and promoting them with each iteration.
Modernise your apps and data
Modernise iteratively at any stage
Modernisation involves refactoring, rearchitecting or rebuilding your apps and data. Use modernisation to achieve benefits like boosting app innovation, increasing agility and accelerating developer velocity. You may modernise at any stage—before, during or after migrating your workloads.
Refactor apps and databases for speed and productivity
Refactor—or repackage—when you want to make minimal changes to apps so that they connect easily to Azure. For example, refactor relational databases directly into a cloud database service like Azure SQL Database.
Rearchitect apps and databases for cloud scalability and productivity
Rearchitect when you want to modify and extend app functionality and code to optimise for cloud scalability. For example, break down monolithic apps into groups of microservices that work together and scale easily.
Rebuild with cloud-native technologies to accelerate developer velocity
Rebuild when you need to recreate an app using Azure cloud solutions. Consider rebuilding if your existing apps have limited functionality or lifespan.

Modernisation tools and guidance
Easily govern, secure and manage cloud environments.
Govern and secure your workloads
Get visibility into and more control over your security posture
Quickly detect and respond to threats across hybrid environments with intelligent threat protection from a solution like the Azure Security Center. Help secure your entire organisation from threats with cloud-native SIEM solutions like Azure Sentinel.
Build and scale your apps and workloads quickly while maintaining control
Building on your landing zone work, establish and maintain the right mix of standard and custom policies to govern your cloud subscriptions and resources—in a way that stays compliant.
Manage and cost-optimise your cloud environments
Become familiar with the tools, offers and guidance from your cloud provider
Monitor and adjust cloud spend and drive operational efficiencies with exclusive offers. For example, use reserved instance discounts or reuse your on-premises licences in the cloud.
Manage your workloads across all environments with a solution like Azure Arc. Monitor workload performance with real-time insights and trends. Help ensure your workloads stay protected with cloud backup and disaster recovery solutions.
Security and management
Move your existing apps to Azure in an optimised way—without code changes—using a lift-and-shift migration. As-is app migration to cloud infrastructure as a service helps you flip capital expenditures to operational expenditures and quickly gain agility and scale. Typical projects include:
Modify or extend your apps to further scale and optimise for cloud architectures. Take advantage of Azure platform as a service capabilities such as built-in security, patching, high availability and auto-scaling. Typical projects include:
