Procedure
1 On the node on which the vCenter Single Sign-On 5.5 service runs, set up the environment so the
vCenter Single Sign-On 6.x service is known.
a Back up all files C:\ProgramData\VMware\CIS\cfg\vmdird.
b Make a copy of the vmdircert.pem file on the 6.x node, and rename it to
<sso_node2.domain.com>.pem, where <sso_node2.domain.com> is the FQDN of the 6.x node.
c Copy the renamed certificate to C:\ProgramData\VMware\CIS\cfg\vmdird to replace the
existing replication certificate.
2 Restart the VMware Directory Service on all machines where you replaced certificates.
You can restart the service from the vSphere Web Client or use the service-control command.
Use VMCA as an Intermediate Certificate Authority
You can replace the VMCA root certificate with a third-party CA-signed certificate that includes VMCA in
the certificate chain. Going forward, all certificates that VMCA generates include the full chain. You can
replace existing certificates with newly generated certificates.
Procedure
1 Replace the Root Certificate (Intermediate CA)
The first step in replacing the VMCA certificates with custom certificates is generating a CSR,
sending the CSR to be signed. You then add the signed certificate to VMCA as a root certificate.
2 Replace Machine SSL Certificates (Intermediate CA)
After you have received the signed certificate from the CA and made it the VMCA root certificate,
you can replace all machine SSL certificates.
3 Replace Solution User Certificates (Intermediate CA)
After you replace the machine SSL certificates, you can replace the solution user certificates.
4 Replace the VMware Directory Service Certificate in Mixed Mode Environments
During upgrade, your environment might temporarily include both vCenter Single Sign-On version
5.5 and vCenter Single Sign-On version 6.x. For that case, you have to perform additional steps to
replace the VMware Directory Service SSL certificate if you replace the SSL certificate of the node
on which the vCenter Single Sign-On service is running.
Replace the Root Certificate (Intermediate CA)
The first step in replacing the VMCA certificates with custom certificates is generating a CSR, sending the
CSR to be signed. You then add the signed certificate to VMCA as a root certificate.
You can use the Certificate Manager utility or other tool to generate the CSR. The CSR must meet the
following requirements:
n
Key size: 2048 bits or more
