Migrating ESX to ESXi

image

Just released on the VMware Flings site is a fling which is designed to help when you make the move from ESX to ESXi, this tool will help you check hardware software and also that there are no lingering scripts or locally stored VMs etc.

A great tool to download and run against your environment to ensure you have caught everything before the move to the next version of ESXi.

From the official description:

The ESX System Analyzer is a tool designed to help administrators plan a migration from ESX to ESXi. It analyzes the ESX hosts in your environment and, for each host, collects information on factors that pertain to the migration process:

  • Hardware compatibility with ESXi
  • VMs registered on the ESX host, as well as VMs located on the host’s local disk
  • Modifications to the Service Console
    • RPMs which have been added or removed
    • Files which have been added
    • Users and cronjobs which have been added

This tool also provides summary information for the whole existing environment

  • Version of VMware Tools and Virtual Hardware for all VMs
  • Version of Filesystem for all datastores

By having this information, administrators can determine what tasks need to be done prior to the migration. Examples include:

  • Relocate VMs from local datastores to shared datastores
  • Make note of what agent software has been added to the host and obtain the equivalent agentless version
  • Replace cronjobs with equivalent remote scripts written with PowerCLI or vCLI
