 •Getting started with virtual migration •Performing server migrations with Microsoft's Hyper-V •Using VMware for virtual server migrations One of the most significant benefits of server virtualization is the ability to move virtual machine (VM) workloads across hosts in your environment. Virtual server migrations limit downtime and enable administrators to rapidly allocate resources to certain VMs as needed. This server migration guide provides the information you need to get started with physical and virtual migrations. The first section covers server migration planning and tools, and it outlines how successful server migrations can ease data center overhauls. The second section explains how to perform successful migrations with Microsoft Hyper-V. Specific topics include how to migrate workloads from Microsoft Virtual Server to Hyper-V and how to use Microsoft System Center Virtual Machine Manager to ease management tasks. The third section of this guide explores virtual server migrations in VMware environments. These articles show you how to use VMware's VMotion migration management tool, migrate to ESX 3.5 and troubleshoot failed conversions. Getting started with virtual server migration Virtual server migrations can be a daunting task. But the benefits of consolidating physical systems into virtual machines are more than worth it. This section outlines the planning for virtual server migrations and the tools you can use in the process, and it explains how successful migrations can increase data center efficiency. Virtual machine server migrationFor some IT shops, virtual server migrations can be challenging, which may prompt admins to blame the migration process and scrap a virtualization deployment altogether. Burton Group analyst Chris Wolf outlines three approaches to migrating physical servers to virtual machines. P2V migration tools If you plan on converting physical machines to virtual servers, you should be aware of potential server migration problems such as hardware compatibility. An expert evaluates virtual server migration tools to contend with physical-to-virtual (P2V) migration challenges and discusses how to deal with possible driver recognition issues and server downtime. Using P2V backup and restore in a disaster recovery strategy You can implement a disaster recovery strategy for physical servers using physical-to-virtual (P2V) disk files. An expert explains how disaster recovery for virtual servers differs from DR for physical ones, outlines how to create a P2V backup and restore plan, and evaluates tools for backup and recovery of virtualized environments. Why unvirtualize? While many server migrations involve converting physical machines to virtual ones, there are several scenarios in which you many need virtual-to-physical migration (V2P) tools. Virtual server migration from a physical system can create support problems that force you to revert to a physical architecture, virtual servers at a remote disaster recovery site may need to be unvirtualized or performance problems may prompt a V2P migration. An expert provides pointers on why and how to perform V2P conversions. How P2V migrations can ease data center moves Relocating a data center can be complex, costly and risky. But migrating physical servers to virtual machines can reduce the costs, risk and downtime involved in moving a data center. An expert explains the intricacies of the process. Performing virtual server migrations with Microsoft Hyper-V Hyper-V is Microsoft's server virtualization technology that is attempting to rival VMware. It is still a relatively nascent technology, but it is becoming increasingly prevalent in enterprise-level data centers. This section addresses virtual server migrations in Hyper-V infrastructures, including the tools you can use and how to convert Microsoft Virtual Server to Hyper-V environments. Migrating to Hyper-V VMs: Conversion tool optionsBy using either Microsoft System Center Virtual Machine Manager or Vizioncore vConverter, you can convert existing workloads to Hyper-V virtual machines. An expert explains what you should consider before converting your workloads and how to properly utilize these tools to achieve best results when performing virtual server migrations to Hyper-V. Migrating from Microsoft Virtual Server to Hyper-V Microsoft's Hyper-V offers several advantages (such as Quick Migration and advanced management tools) over its predecessor, Microsoft Virtual Server, which may prompt you to upgrade. An expert offers step-by-step directions for performing a virtual-to-virtual server migration from Virtual Server to Hyper-V. Live Migration in Hyper-V R2 Microsoft Windows Server 2008 R2 will feature Live Migration in Hyper-V. This new technology allows you to perform virtual server migrations between hosts with zero downtime. This tip explains how to get started with Live Migration. Migrating Microsoft Virtual Server to Hyper-V Microsoft's Hyper-V has prompted many administrators to switch from Microsoft Virtual Server (MVS) because of its advanced technologies, superior management tools and speed. An expert provides a tutorial on virtual server migration from MVS to Hyper-V. Performing Windows P2V conversion with PlateSpin Migrate Using VMware for virtual server migrations VMware's ESX platform is the most widely adopted virtualization platform in enterprise-level data centers. This section explores planning for virtual server migrations with VMware ESX, using VMware's live migration tool VMotion to perform virtual server migrations and how to correct failed migrations. VMware Server to ESX 3.5: Four steps for a successful migrationBy evaluating your current environment, designing your virtual infrastructure and testing your virtual server migrations before you perform them, you can ease the task of upgrading from VMware Server to VMware ESX 3.5. An expert walks you through the process. Upgrading from VMware Server to ESX 3.5: The pros and cons With better flexibility, functionality, data center control and management tools, migrating your virtual servers from VMware Server to ESX 3.5 is a no-brainer. One word of warning, though: If you implement IDE and dynamic disks you will confront issues. Upgrading Exchange Server? Migrate to ESX If you move your Exchange Server 2007 into your VMware ESX server infrastructure, you'll get better performance and more storage space. But running Exchange as a virtual server requires specific hardware and can put service agreements in peril. VMware DRS and VMotion: Improve workload balance, prevent problems VMware Distributed Resource Scheduler (DRS) and VMotion have the unique ability to work on their own for certain tasks, and together on others such as virtual server migrations. An expert offers his advice on how to get the most out of your virtual machines if choose to run both technologies. Troubleshooting failed VMware Converter P2V migrations Performing a virtual server migration with VMware Converter is fraught with potential roadblocks. An expert offers some tips on planning for the migration and troubleshooting tactics to address the issues you may encounter. How to obtain, configure and use VMotion and how VMotion works VMware VMotion allows you to perform virtual server migrations between ESX hosts with no downtime. An expert explains how VMotion works, how to configure it for your virtual infrastructure and the scenarios where you should use it.
