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 redesignin...

Legacy ETL pipelines were designed for an earlier generation of data warehousing. They extract, transform and load data in a rigid sequence, which introduces complexity and potential failure points. As data volumes grow and business requirements evolve, the transformation step becomes a bottleneck and batch processing leaves the warehouse perpetually out‑of‑date. Modifying transformation logic often necessitates rebuilding the entire pipeline, making legacy ETL systems inflexible and risky to change. These inherent challenges mean organizations struggle to load data into modern warehouses and lakes efficiently. Manual code conversion from legacy ETL languages to cloud‑native formats adds another layer of complexity. Rewriting and translating each line of code can take years and requires specialized expertise. Datametica’s Raven tool addresses this bottleneck by automating the conversion process. Raven rapidly converts legacy code and enforces consistent standards across the codebase, s...
