If a security certificate for a VMware VirtualCenter server expires, or a self-signed certificate is replaced by a third-party CA Certificate, you must update the configuration in VMware VirtualCenter and in Virtual Machine Manager. The following procedure explains the changes that are required.To update configurations after a certificate change on a VirtualCenter server
To replace the current VMware VirtualCenter self-signed certificate with a new self-signed or third-party CA certificate in VMware VirtualCenter, follow the instructions in the VMware Infrastructure SDK Developer’s Setup Guide, which is available on the VMware Infrastructure SDK Support and Resource site (http://go.microsoft.com/fwlink/?LinkId=121744).
After replacing the certificate on the VirtualCenter server, run the following Windows PowerShell cmdlets on the VMM server, where VirtMgrServer01.Contoso.com is the FQDN of the VirtualCenter server:
$Virtman = Get-virtualizationmanager –computername “VirtMgrServer01.Contoso.com”
$Cert = Get-certificate –computername “VirtMgrServer01.Contoso.com”
Set-VirtualizationManager –VirtualizationManager -$VirtMan –Certificate $Cert
Note Security certificates can only be updated from the command line.
