Via a Perl Script, a very helpful post can be found here:
If you’d rather use PowerShell, check out this helpful blog post which also references a follow-up VMware community post:
Potential issue if you are using VMware Changed Block Tracking and NFS storage.
Here is a very useful KB article on migrating an existing vCenter Server database to 4.1 using the Data Migration Tool:
Also, here’s a great blog post on VMware’s blog showing how to upgrade vCenter 4.0 32 bit to vCenter 4.1 64 bit by using the VMware Data Migration Tool.
Our first video covering vSphere 4.1 is now live. The video compliments KB article 1022137 vSphere 4.1 upgrade pre-installation requirements and considerations. and describes the process for using our Data Migration tool to upgrade VMware vCenter Server 4.1
VMware vCenter 4.1 is part of the VMware vSphere 4.1 product suite and the Data Migration tool allows you to migrate your vCenter Server 4.0 configuration, since VMware has now entirely gone to a 64-bit platform. 64-bit brings significant performance benefits, but it also introduces some challenges that need to be considered before upgrading.
Sit back, grab that cup of java and take in a little KBTV.
The Data Migration tool is provided with your vCenter Server 4.1 installation media.

Chethan Kumar has recently updated the Performance Troubleshooting for vSphere 4.1 guide. This is a great asset I use regularly for any client or partner that asks about vSphere performance – especially those working with Tier 1 applications. It is very educational and addresses the most common scenarios clients experience.
“The hugely popular Performance Troubleshooting for VMware vSphere 4 guide is now updated for vSphere 4.1 . This document provides step-by-step approach for troubleshooting most common performance problems in vSphere-based virtual environments. The steps discussed in the document use performance data and charts readily available in the vSphere Client and esxtop to aid the troubleshooting flows. Each performance troubleshooting flow has two parts:
1. How to identify the problem using specific performance counters.
2. Possible causes of the problem and solutions to solve it.”
