Public or private cloud migration is a strategic process where we assess your IBM i environment, identify interdependencies, and design a tailored roadmap to move workloads into public or private clouds with enhanced security, agility, and cost optimization. On the other hand, lift-and-shift is a faster migration approach that moves workloads with no major changes to application stacks. The former is better for long-term scalability and modernization while the latter is ideal when cost-efficiency and speed are priorities.
