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.

Note: 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.



  1. If the VMware VirtualCenter Server service on the source host is running, stop it.
    1. In the Windows Administrative Tools control panel, double-click Services.
    2. Right-click VMware VirtualCenter Server and select Stop.
  2. 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.

  3. Create the following SSL folder on the host machine where you will install the new instance of vCenter Server: C:\ProgramData\VMware\VMwareVirtualCenter\SSL.
  4. Paste the copied certificates in the folder C:\ProgramData\VMware\VMware VirtualCenter\SSL.
  5. Create a 64-bit DSN that points to the legacy vCenter Server database and database user.
