Background and Importance of Virtualization Migration

Virtualization migration is the complex process of moving virtual machines from one virtualization platform to another, typically involving migration from traditional platforms like VMware vSphere to more modern and flexible cloud environments. As enterprises increasingly demand hybrid cloud and containerization technologies, virtualization migration has become a critical step in IT modernization. Whether the goal is to reduce operational costs, improve resource utilization, or adapt to new technical architectures, choosing the right migration tool is essential. Below, we will detail three mainstream virtualization migration tools and explore how they help enterprises achieve seamless migration from VMware to other platforms.

Migration Toolkit for Virtualization (MTV)

Red Hat’s Migration Toolkit for Virtualization (MTV) is a tool specifically designed for virtual machine migration, aimed at helping users migrate virtual machines from VMware vSphere, Red Hat Virtualization, or OpenStack to the OpenShift Virtualization platform. MTV integrates into the OpenShift interface, providing an intuitive migration experience. It supports both cold migration and warm migration modes. Cold migration requires shutting down the source virtual machine to complete data replication, while warm migration uses incremental replication to reduce downtime, making it particularly suitable for scenarios with high business continuity requirements.

MTV is relatively simple to install and configure, and users can deploy it with one click via the OpenShift OperatorHub. The tool leverages VMware Virtual Disk Development Kit (VDDK) to accelerate disk transfers and supports network and storage mapping to ensure consistent network and storage settings for virtual machines after migration. However, MTV heavily depends on the OpenShift environment, which may limit its applicability for enterprises not using the Red Hat ecosystem. Additionally, warm migration requires enabling Change Block Tracking (CBT) for each virtual machine and supports a maximum of 28 CBT snapshots. Excessive snapshots may cause migration failures.

ZStack V2V: The Preferred Solution for Efficient Migration

ZStack V2V is a virtualization migration tool specifically designed for migrating from VMware to ZStack. It has gained widespread attention for its efficiency, flexibility, and ease of use. ZStack V2V simplifies the complexity of migrating from VMware to the ZStack platform through an automated migration process.
