Legacy to Cloud Migration

Legacy systems are the backbone of many enterprises, but they carry growing risks: rising maintenance costs, security vulnerabilities, difficulty finding developers who know outdated frameworks, and an inability to scale for modern workloads. Cloud migration is not just a technology upgrade; it is a strategic business transformation.

At Unicodez, we approach every migration with a deep understanding that your legacy systems contain decades of business logic and institutional knowledge. We do not take a rip-and-replace approach. Instead, we carefully assess each application, understand its dependencies, and design a migration strategy that preserves your business continuity while unlocking the benefits of the cloud.

Our migration methodology covers all six R strategies: Rehost (lift and shift), Re-platform (lift and optimize), Refactor (re-architect for cloud-native), Repurchase (move to SaaS), Retire (decommission), and Retain (keep on-premises). We recommend the right strategy for each workload based on business value, technical complexity, and cost-benefit analysis.

Database migration is often the most critical and complex part of a cloud journey. We specialize in migrating on-premises databases including Oracle, SQL Server, MySQL, and legacy mainframe databases to modern cloud-native alternatives like Amazon RDS, Azure SQL, Google Cloud SQL, or fully managed NoSQL services. We handle schema conversion, data validation, and continuous replication to ensure zero data loss.

Security and compliance are paramount during migration. We implement encryption for data in transit and at rest, configure IAM policies with least-privilege access, set up VPC networking with proper segmentation, and ensure your migrated environment meets SOC 2, HIPAA, GDPR, or industry-specific compliance requirements from day one.

Post-migration, we do not just hand over the keys. We optimize your cloud environment for cost efficiency using reserved instances, auto-scaling policies, and right-sizing analysis. Our clients typically see 30-50 percent cost savings compared to their legacy on-premises infrastructure, along with dramatically improved scalability and reliability.
