When you migrate from a Windows Server 2003 host to a host that is supported for vCenter Single Sign-On 5.5, you can also migrate the vCenter Server database and SSL certificates.


This task assumes that your existing vCenter Server uses a custom database. The steps in this task assume that you install vCenter Server and components in the default location. If you use a different location, adjust the paths accordingly.

Verify that the host machine meets the requirements for vCenter Server 5.5. See System Requirements.

Review the topics in Preparing for the Upgrade to vCenter Server.


If the VMware VirtualCenter Server service on the source host is running, stop it.


In the Windows Administrative Tools control panel, double-click Services.


Right-click VMware VirtualCenter Server and select Stop.


Copy the SSL certificates from the VMware VirtualCenter\SSL folder of the source machine.

The folder is located at C:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter\SSL.


Create the following SSL folder on the host machine where you will install the new instance of vCenter Server: C:\ProgramData\VMware\VMwareVirtualCenter\SSL.


Paste the copied certificates in the folder C:\ProgramData\VMware\VMware VirtualCenter\SSL.


Create a 64-bit DSN that points to the legacy vCenter Server database and database user.
