Important: Ensure that the certificate contains the FQDN of the VIP and all PSCs participating in PSC HA.
See the section ‘Preparing a Certificate’ earlier in this guide.
Installing a new Certificate
Install the new Certificate on all PSCs participating in PSC HA.
Use the Certificate-Manager Option 1 to do this.
See the section ‘Replacing the Machine SSL Certificate‘ earlier in this guide.
Restart vCenter Servers
If the PSC Certificates have changed, you must restart all vCenter Server instances that are associated with this PSC HA instance.
Other solutions like SRM, VRA, NSX, may need to be re-registered with the PSC HA Instance.
