Recover capacity at migration time

Migrating from VMware creates both a platform transition and a critical capacity-planning challenge. Organizations must maintain workload performance during the move while identifying opportunities to reclaim underused compute and memory resources.

This technical guide explains how organizations can recover capacity before, during, and after migrating virtual machines to Red Hat OpenShift Virtualization. It covers VM assessment and rightsizing, migration-wave planning, memory-efficiency mechanisms, intelligent workload placement, hybrid cloud capacity, and longer-term modernization from VMs to containers.

• How to assess and rightsize an existing VMware estate before migration
• How to manage temporary capacity constraints through phased migration waves
• Why layered memory controls can improve VM density and hardware utilization
• How a unified platform supports ongoing optimization and future containerization
