Modern enterprises must move decisively to the cloud or risk falling behind. Today, more than 85% of organizations will be “cloud-first” by 2025, and new digital workloads are overwhelmingly begin in the cloud. A well‑structured cloud migration plan is critical for executives to achieve business agility, control costs, and mitigate risk. For example, Teleglobal helped a media client cut storage costs by ~90% during cloud modernization.

In this 7-step roadmap, we outline concrete actions from defining objectives to optimizing operations, so your migration delivers measurable ROI, secure operations, and on-schedule execution.

Step 1: Define Strategy & Business Case

Begin with a clear cloud strategy and business case. Set top‑level goals (cost reduction, agility, innovation) and success metrics before any technical work. At this stage, the board must agree on “why cloud?” – whether for cost savings, speed to market, resilience, or digital transformation.

Step 2: Assess Current Environment & Plan Migration

After strategy, perform a detailed assessment and planning. Conduct a cloud readiness assessment of your existing IT landscape: inventory servers, databases, dependencies, network, security posture, and compliance gaps. This inventory should be automated where possible. Identify application categories (e.g. by business-critical vs. infrequently used) and data sensitivity.

Step 3: Establish Governance & Team

With a plan in hand, formalize your governance and operating model. Establish a Cloud Center of Excellence (CCoE) or steering group to oversee the migration. This team typically includes architects, security leads, financial controllers, and a lead “cloud migration manager.”

Step 4: Design & Pilot

Before a full migration, run a pilot or proof-of-concept. Design your target cloud architecture and security, then test it on a small, non-critical workload. This step validates your assumptions (performance, integration, user experience) and uncovers hidden issues early. Choose an application that represents typical technical challenges.

Step 5: Migrate Workloads

Execute the migration waves as planned. Move applications in phases, typically starting with lower-risk systems. Common approaches include rehosting (“lift-and-shift”), replatforming, or refactoring per the 7 Rs strategies. Use automation and tools wherever possible (infrastructure as code, database replication services) to accelerate the process and reduce errors.

Step 6: FinOps & Cost Governance

Once services run in the cloud, implement FinOps (cloud financial operations) best practices. According to Deloitte, companies that establish FinOps can save billions (and cut cloud costs up to 40%). Assign financial ownership of resources (via tagging) so each department is accountable for its spend. Set budgets and alerts in your cloud consoles, enforce approvals for unplanned expenses. 

Step 7: Optimize & Operate Continuously

Migration isn’t the finish line, now you optimize. Monitor performance, reliability, and security 24/7. Utilize cloud-native services to improve your apps (managed databases, serverless functions, advanced analytics). Regularly review your architecture in a “well‑architected review” or similar to catch inefficiencies. Automate routine operations (CI/CD for deployments, auto-remediation scripts).

Common Migration Challenges and Mitigations

Underestimated Dependencies

Cost Surprises

Skill Gaps

Security Gaps

Resistance to Change

A successful cloud migration demands a balance of strategic vision and disciplined execution. By following these 7 steps from defining objectives through continuous optimization – executives can ensure the project drives real business value. Leadership attention to governance, KPIs, and cost oversight (FinOps) will keep the plan on track.

Introduction

As technology evolves, businesses must adapt to stay competitive. Many organizations still rely on legacy systems that limit innovation and slow down growth. Adopting a cloud-based infrastructure is one of the most effective ways to overcome these challenges.

A well-planned legacy application migration to the cloud can improve agility, enhance performance, and future-proof your business operations.

Understanding Legacy Systems

Legacy systems are outdated applications that continue to support core business functions. While they may still work, they often:

Lack scalability

Require high maintenance costs

Struggle with integration

Pose security risks

Benefits of Moving to the Cloud

Migrating to the cloud unlocks multiple advantages:

Flexibility: Access applications anytime, anywhere

Cost Optimization: Pay only for what you use

Stronger Security: Advanced data protection features

Faster Innovation: Easy integration with modern tools

Improved Efficiency: Streamlined operations and workflows

Steps to Migrate Legacy Applications

1. Evaluate Current Infrastructure

Identify system dependencies, performance gaps, and migration readiness.

2. Select the Best Migration Approach

Choose between lift-and-shift, replatforming, or complete modernization based on your business goals.

3. Ensure Data Integrity

Secure and validate all data during migration to prevent loss or corruption.

4. Implement Cloud Security Measures

Use encryption, access controls, and monitoring tools to safeguard your data.

5. Monitor and Optimize

After migration, continuously monitor performance and optimize for better results.

Challenges You May Face

Compatibility issues with modern platforms

Temporary downtime during migration

Need for skilled cloud professionals

Managing large volumes of data

Proper planning and expert guidance can significantly reduce these risks.

Conclusion

Cloud migration is no longer optional—it’s essential for businesses aiming to grow in a digital-first world. Modernizing legacy applications enables better scalability, improved security, and long-term efficiency.
