Seven steps for a successful Azure migration

1. Review Current IT Environment

Evaluate your IT setup to identify any hurdles and opportunities for a smooth migration to Azure. Start by listing and analysing your resources.

List All IT Assets

Create an inventory of all your hardware, software, and data. Include:

• Server Infrastructure: Physical and virtual servers, operating systems, and their specifications.
• Applications: Critical business software, development tools, and custom-built applications.
• Databases: Types, sizes, and any dependencies.
• Network Components: Firewalls, load balancers, and connectivity needs.

Make sure to map out system dependencies to avoid disruptions during the migration process.

Monitor System Usage

Understanding how your current resources are used can help you allocate Azure resources efficiently and manage costs. Focus on these key metrics:

Track these metrics for at least 30 days to establish a reliable usage baseline.

Check Azure Compatibility

Use Azure Migrate to evaluate compatibility. This tool provides:

1. Compatibility Reports: Detailed insights into which systems can move directly to Azure and which may need adjustments.
2. Migration Recommendations: Tailored suggestions for Azure services and configurations based on your current setup.
3. Cost Estimates: Predicted Azure expenses based on your resource usage.

Run these checks on all systems planned for migration, paying close attention to legacy and custom software. These may need updates or modifications before they can be moved to Azure.

2. Create Migration Plan

Build a migration plan that aligns with your business goals and resource constraints. Use your IT review to define clear objectives and allocate resources effectively.

Set Migration Targets

Define measurable goals for your Azure migration by focusing on key areas:

Include these goals in your migration plan and schedule regular reviews to monitor progress.

Calculate Total Costs

Perform a detailed cost assessment using the Azure Pricing Calculator to avoid unexpected expenses. Factor in:

• Direct Azure Costs:
  • Virtual machines and storage
  • Network bandwidth and data transfer
  • Backup and disaster recovery
  • Security and monitoring solutions
• Migration-Related Expenses:
  • Staff training and certifications
  • Third-party migration tools
  • Temporary parallel environments
  • A contingency buffer (suggested at 15% of the total budget)

Rank Migration Tasks

Organise workloads based on their business importance and complexity. Use the following framework to prioritise:

Start with workloads that provide the best mix of low risk and high value. For instance, migrate development and testing environments first before moving to production systems.

3. Set Up Azure Platform

Once your migration plan is ready, the next step is to configure your Azure environment to bring it to life.

Structure Resource Groups

Organise your Azure resources systematically by creating a clear structure. Stick to a consistent naming convention that mirrors your business framework. For small and medium-sized businesses (SMBs), grouping resources by their function often works well. Here's an example:

You can also use tags like BusinessUnit, CostCentre, Environment, Owner, and SecurityLevel to keep track of costs and manage resources efficiently.

Set Up Network Settings

Design your network with clear subnet segmentation to ensure smooth operations.

1. Create Virtual Networks A typical setup for SMBs might look like this:

   Environment	Address Space	Subnet Range	Purpose
   Production	10.0.0.0/16	10.0.1.0/24	Primary workloads
   Development	172.16.0.0/16	172.16.1.0/24	Testing and development
   Management	192.168.0.0/16	192.168.1.0/24	Administrative access

2. Implement Security Measures Protect your resources by deploying Network Security Groups (NSGs) to control traffic flow. For applications exposed to the internet, consider using Azure Firewall for advanced threat protection.

Once your network is secure, focus on managing user access effectively.

Configure Access Controls

Leverage Azure Active Directory to manage identity and access. Always follow the principle of least privilege when assigning permissions. For example:

To enhance security, enable Multi-Factor Authentication (MFA) for all users. Use Conditional Access policies to restrict logins based on factors such as:

• Location
• Device compliance
• Risk level
• Time of day

Additionally, activate Azure AD Identity Protection to detect and respond to potential threats proactively.

4. Test Before Migration

Run tests in a controlled setup to spot any problems with data accuracy, performance, or system compatibility.

Test with Sample Data

Set up a test environment that matches your planned Azure configuration. Start by migrating a small portion of your data and less critical applications. Check for issues with data accuracy, system functionality, integrations, and security. Use what you learn to adjust and improve your migration plan.

Check Backup Systems

Ensure your backup systems are functioning properly before starting the migration. Set up a primary backup solution that meets your business needs. For added safety, think about secondary options like geographic replication or point-in-time recovery. Regularly test your recovery processes to confirm backups can be restored when needed.

Train Your Team

Make sure your staff are prepared for the transition. Provide training on Azure operations, troubleshooting, security measures, and handling emergencies. Maintain clear communication channels and document all training sessions. Focus on:

• Basic Azure operations for all employees
• Migration tools and troubleshooting for IT teams
• Security practices for system users
• Emergency protocols for support staff

Once testing is done, you can move on to migrating your systems in stages and fine-tuning the setup in the next steps.

5. Migrate and Fine-tune

After testing, it's time to carry out the migration and make adjustments step by step.

Move Systems in Phases

To reduce disruptions, start with less critical systems. Begin with development environments and test servers, then move on to production systems. Plan the migration sequence based on how systems depend on each other and their importance to your operations.

Once the systems are migrated, shift your attention to refining Azure settings.

Fine-tune Azure Settings

Adjust your Azure setup to balance performance and cost. Use tools like Azure Cost Management to monitor expenses and Azure Advisor for improvement tips.

Focus on these areas for optimisation:

• Review CPU and memory usage to ensure virtual machines (VMs) are appropriately sized.
• Set up auto-scaling to handle varying workloads efficiently.
• Apply lifecycle policies to manage storage effectively.
