This new video from KBTV is about upgrading the vCenter 4.0 to 4.1 by using a script. vCenter 4.1 is not supported on 32 bits systems any more. In case you do have your existing vCenter on 32 bit system, you have to reinstall, or choose another server and install the server with 64 bit Microsoft operating system. There is a new script present on the installation ISO which you previously downloaded from VMware’s Website. The script is present in the root of the installation media in the folder called datamigration. By running this script you’ll be able to migrate your vCenter Server .
What you must do?
You must first unzip the file containing the script (to the local c: drive for example), then stop the vCenter and Vmware update manager services. Then with a command prompt type backup.bat in the C:
Then you just copy the whole folder from your c:\datamigration to your new 64bit Server via the network for example.
On the new vCenter Server first put the DVD with the vCenter 4.1 into the DVD drive. Type Install.bat in command prompt and follow the informations asked in the script (like if there is a netbios name change or drive letter of your DVD drive). After those questions, the installation is launched.
This 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
