Experience an Enhanced Virtualized Environment Fast: Vizioncore Offers Ten Steps for a Successful Migration to VMware(R) Infrastructure 3.Leading backup and recovery software provider for VMware offers white paper titled "Best Practices for Migrations to VMware Infrastructure 3" BUFFALO GROVE Buffalo Grove A village of northeast Illinois, a suburb of Chicago. Population: 43,300. , Ill. -- Without a doubt, VMware[R] Infrastructure 3 (VI3) offers more robust, enterprise-level functionality compared with VMware ESX Server VMware ESX Server is an enterprise-level virtualization product offered by VMware, Inc., a division of EMC Corporation. ESX Server is a component of VMware's larger offering, Virtual Infrastructure, which adds management and reliability services to the core server product. 2.X. Some of the more significant improvements include the ability to run more simultaneous virtual machines; high-availability options that allow for SAN-path failover Invoking a secondary system to take over when the primary system fails. Up-to-date copies of all required data and applications are maintained on the secondary system in order to respond immediately if the primary system becomes unusable. Also called "fallover." See replication. , expanded hardware support, 64-bit compatibility, and enhanced network security. To gain the business value of these improvements fast, consider the following advice from the experts at Vizioncore: To take advantage of the VI3 improvements, all of your existing virtual machines must be migrated from ESX See VMware. Server 2.X to the new platform. Depending on how many virtual machines you are running, scheduling migrations and cutovers can become complicated, and downtime The time during which a computer is not functioning due to hardware, operating system or application program failure. can become substantial. However, with proper procedures, you can upgrade smoothly so your company can more quickly take advantage of the new features. VMware outlines two main methods of performing migrations. The first, "in-place" migrations, involves selecting a particular ESX Server host (and all associated virtual machines) and isolating i·so·late tr.v. i·so·lat·ed, i·so·lat·ing, i·so·lates 1. To set apart or cut off from others. 2. To place in quarantine. 3. it for an entire upgrade at once. The second, "migration upgrades," involves selecting individual virtual machines and migrating them to a new LUN or piece of hardware upon which the VMFS VMFS Virtual Machine File System (VMware) VMFS Virtual Mirror File System and datastores have already been upgraded. In both cases, the migration methods offered by VMware(a) may be supplemented with third-party software to automate To turn a set of manual steps into an operation that goes by itself. See automation. migrations and fast-track infrastructures to enterprise functionality for virtualized environments. By following these ten steps, companies undertaking VI3 migrations can make sure the process proceeds as smoothly and quickly to ensure fast time-to-business value: * Read all documentation thoroughly before you begin: VMware documentation identifies the needed steps, offers specific recommendations, and outlines the expected downtime of any given step. Reading through this documentation is a critical first step in understanding all the variables for migrations in your virtual environments. * Identify each virtual machine and its associated host for migration: Create an inventory of your virtual machines and catalog catalog, descriptive list, on cards or in a book, of the contents of a library. Assurbanipal's library at Nineveh was cataloged on shelves of slate. The first known subject catalog was compiled by Callimachus at the Alexandrian Library in the 3d cent. B.C. them in one central document. This step ensures you do not miss any virtual machines in the upgrade process. * Map interdependencies of virtual machines: Building a map of dependencies among virtual machines is an essential step to flagging their importance in order to minimize downtime of the most critical virtual machines. * Create a schedule and workflow The automatic routing of documents to the users responsible for working on them. Workflow is concerned with providing the information required to support each step of the business cycle. of virtual machines in required order: Generally speaking, it is a good practice to perform migrations based on the service level associated with individual machines or groups of virtual machines. * Identify the method of migration: Whether you pursue an in-place migration or a migration-upgrade strategy depends on the complexity of your virtual environment and the service levels of your applications. * Back-up your existing virtual machines and establish a fail-back strategy: The most important step in a migration procedure is to begin with a back-up of your existing infrastructure. If anything fails during the migration, you will have no virtual machines to restore unless you perform this critical step. * Always begin with a test virtual machine: Testing virtual machine migrations is a highly recommended step in order to uncover any issues that you may have that the documentation does not address. * Perform migration steps in sequential order: There are four key steps in the migration process that must be performed in sequential order. Failure to follow this order can cause problems. These steps are: 1) install VirtualCenter 2.0, 2) upgrade the VMFS, datastores and hosts, 3) migrate virtual machines, and 4) install VMware Tools in each guest. * Manage your downtime window effectively: The amount of downtime you can expect is based on the size of the virtual machine and its interdependencies. It is important to ensure that you employ an acceptable maintenance window during which the application will not be available. * Leverage automation whenever possible: You need to choose tools that match the requirements of your environment. For example, esxMigrator from Vizioncore can migrate virtual machines to dissimilar hardware, can fail back to ESX Server 2.X if needed, automatically upgrades VMware Tools, and retains network identity and connections of virtual machines, among other key features. esxMigrator does not require a SAN or VirtualCenter to perform migrations and is easy to use by any level of administrator.

For Keith Aasen, Consolidation and Virtualization An umbrella term for enhancing a computer's ability to do work. Following are the ways virtualization is used. Hardware Virtualization Partitioning the computer's memory into separate and isolated "virtual machines" simulates multiple machines within one physical computer. Specialist at Long View Systems, a leading IT solution provider that offers system consultation, design and implementation for both physical and virtual environments, selecting the right tools and methodology can make the difference between success and failure when migrating to VMware Infrastructure 3. "I highly recommend that companies carefully look at their needs to find the best fit before they embark on Verb 1. embark on - get off the ground; "Who started this company?"; "We embarked on an exciting enterprise"; "I start my day with a good breakfast"; "We began the new semester"; "The afternoon session begins at 4 PM"; "The blood shed started when the partisans the migration process," said Aasen. "As a VMware Premier Partner, we will use only proven tools and methodologies. esxMigrator from Vizioncore allows us to provide the customer a low risk and timely migration to VMware Infrastructure 3. As compared to other options, esxMigrator provides us a back-out plan, allows us to coordinate the mandatory outage out·age n. 1.

We have used this solution to migrate hundreds of virtual machines at several companies. In all cases, we were 100 percent successful with only minutes of downtime."
