Migrating from PSC HA 6.0 to PSC HA 6.5

Prepare your load balancer for PSC 6.5 HA as per the section “Prepare a Load Balancer” in this guide.

Note: The load balancer configuration for PSC 6.0 HA should be compatible with PSC 6.5 HA.

1. Migrate the first Windows based PSC 6.0 server to an Appliance based PSC 6.5

2. Migrate the second Windows based PSC 6.0 server to an Appliance based PSC 6.5

Refer to the documentation on performing Windows to Appliance migrations.

Configure the migrated PSC 6.5 machines for PSC 6.5 HA as per the section “Run the PSC HA 6.5 scripts” in this guide.

1. Migrate the Windows based vCenter Server 6.0 server to an Appliance based vCenter Server 6.5

2. Repeat for any additional vCenter Server 6.0 instances in this SSO Domain.

Refer to the documentation on performing Windows to Appliance migrations.

PSC HA 6.5 supports SSL Termination and SSL Passthrough.

PSC HA 6.0 only supported SSL Termination, which means the Load Balancer contained one certificate and each PSC 6.0 contained their own unique certificate.

In basic terms, SSL Passthrough means that the Load Balancer does not contain any certificate itself, but all PSC 6.5 must contain a shared certificate containing SAN (Subject Alternative Name) values of all PSC 6.5 FQDN participating in PSC HA and the FQDN of the Load Balanced PSC HA Address.

To convert from SSL Termination to SSL Passthrough, perform the following:

1. Preparing a certificate (see section previous in this guide)
2. Replacing the default Machine SSL Certificate (see section previous in this guide)
3. Remove the SSL Certificate attached to the Port 443 VIP on the Load Balancer (refer to the Load Balancer documentation)
4. Restart the vCenter Server services
