VMware Labs presents its latest fling - ESX System Analyzer

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 or files which have been added  or 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
• Replace cronjobs with equivalent remote scripts written with PowerCLI or vCLI
• Make note of what agent software has been added to the host and obtain the equivalent agentless version
