Lift & Shift vs. Modernize: Choosing the Right Data Migration Strategy

Organizations moving to the cloud face a fundamental question: Should you simply lift and shift existing workloads, or should you modernize them? Both approaches offer distinct benefits and challenges. Understanding these differences helps you choose the right path for your business. This article explores both strategies and shows how Onix’s comprehensive approach can guide your decision.

What Is Lift & Shift?

The lift & shift strategy, sometimes called “rehosting,” involves moving applications and data from an existing environment to a new one—typically from on‑premises to cloud—without making significant changes to the application’s architecture or code. This approach is straightforward and can dramatically reduce migration time, making it ideal for organizations seeking a quick path to the cloud.

Because lift & shift does not modify the application, the process is relatively simple. You keep your legacy architecture intact, avoiding the costs and risks of redesigning critical systems. However, you may miss out on the full benefits of cloud scalability and modern features. In many cases, lift & shift serves as the first step, allowing organizations to gain cloud experience before embarking on deeper modernization.

What Does Modernization Mean?

Modernization goes beyond relocating workloads. “Migrate & modernize” involves simultaneously transitioning legacy systems to new environments while updating the underlying technologies. This parallel approach accelerates transformation and minimizes disruption to business operations. Modernization can take several forms:

  • Infrastructure upgrades: Replacing outdated hardware with more efficient, scalable, secure and cost‑effective solutions.

  • Application updates: Refactoring or re‑architecting legacy software to improve functionality, efficiency and compatibility with current platforms.

  • Data Center Exit: Providing comprehensive support for the move from on‑premises facilities to cloud‑based services through assessment, planning and optimization.

By re‑architecting applications or adopting cloud‑native services, modernization unlocks the full potential of cloud computing. It improves performance, reduces technical debt and opens the door to innovative capabilities like AI, analytics and serverless architectures.



Why Onix?

Choosing between lift & shift and modernization isn’t a binary decision; it depends on your goals, budget and timeline. That’s why Onix offers a tailored approach. Onix’s cloud migration team meticulously assesses your IT landscape, optimizes costs and leverages AI‑driven tools to streamline your journey. Whether you’re in a regulated industry or need hybrid solutions for IoT, Onix provides virtual desktops, robust backup systems and ongoing support for a resilient, efficient transformation.

The “What we do” section of Onix’s solution page lists core services:

  • Lift & Shift: For rapid relocation without architectural changes.

  • Migrate & Modernize: Transition and update technologies concurrently.

  • Infrastructure & Application Modernization: Upgrade and modernize aging systems.

  • Data Center Exit: Comprehensive support for leaving on‑prem data centers.

In addition, Onix offers specialized offerings such as automated on‑premise and cloud‑to‑cloud migrations, invoice reverse engineering, modern cloud‑native applications, packaged offerings and pre‑approved PSF packs. These ready‑to‑go solutions accelerate adoption and reduce complexity.

How Does Onix Guide Your Migration?

Onix uses an end‑to‑end framework that covers every phase of your migration:

  • Assessment: Perform IT cost assessments, use AI‑based planning and optimize databases.

  • Foundation: Build secure landing zones for enterprise and regulated industries, and implement infrastructure as code.

  • Migration: Manage VMware and bare‑metal migrations, handle cloud‑to‑cloud moves, support database migration and incorporate validation with Onix’s Pelican tool.

  • Modernization: Provide virtual desktops, backup, disaster recovery and archival solutions.

  • Managed Services & Operations: Offer cloud management, orchestration, monitoring using generative AI and site reliability engineering.

Onix further divides the process into Initiation, Discovery, Assessment, Planning & Readiness, Migration, Integration, Validation and Operations. Each stage ensures that your migration is systematic and aligns with business goals. For example, the Discovery phase includes infrastructure discovery and IT cost reporting, while the Planning & Readiness phase focuses on migration plans, prioritization and building a landing zone.

Introducing Eagle: The Planner

To support these stages, Onix offers Eagle, a planning and optimization tool that sits at the heart of the discovery and assessment process. Named after the eagle’s sharp vision and precise planning, this solution delivers detailed assessments and actionable plans to drive modernization from legacy warehouses to the cloud. Powered by generative AI, Eagle uncovers hidden business logic and creates a smart data catalog and business glossary. This enriched understanding of your data landscape leads to insights that inform every step of your migration and modernization journey. By using Eagle alongside other Onix tools, organizations can make better decisions faster and ensure a smoother transition.

Which Strategy Is Right for You?

Selecting between lift & shift and modernization is not a one‑size‑fits‑all decision. Consider factors such as application complexity, regulatory requirements, performance goals and budget constraints. If you need to move quickly or have minimal resources to refactor, lift & shift may be appropriate. If you’re seeking long‑term gains in efficiency, scalability and innovation, modernization is likely the best choice.

Often, the answer lies in a hybrid approach. You might lift & shift some workloads to reduce immediate costs, then modernize them later when resources and expertise are available. Onix’s flexible portfolio lets you mix and match strategies while still benefiting from structured guidance and AI‑powered tools like Eagle.
