Note: vCenter 4.1 is only available in a 64-bit version. This tutorial is an in place upgrade of a previously installed vCenter 4 64-bit instance which had already been upgraded to Update2. vCenter 4.1 can also be installed as a fresh instance. Don’t forget to upgrade your vSphere Client after completing this tutorial. To migrate from vCenter 4 32-bit version to vCenter 4.1 64-bit version please check the VMware vSphere 4.1 Upgrade Guide in the Resources section under VMware vSphere 4.1
I’am using the following image:
VMware-VIMSetup-all-4.1.0-259021.zip
1. Insert, mount or run the autorun.exe file on the VMware vCenter 4.1 DVD. You will be presented with the screen below. Before we start the installation we want to check each host and make sure they are ready and compatible with version 4.1. Under the Utility menu, click “Agent Pre-Upgrade Check”
Note: If you don’t have vCenter installed and this is a first time install, you will not see this notification.
Make sure you take a backup of the SQL database and SSL certificates before continuing.
