When you upgrade a vCenter Server instance with an embedded vCenter Single Sign-On, you upgrade the entire deployment at the same time.
vCenter Server 5.5 ports that are in use by vCenter Server and vCenter Single Sign-On are preserved. You cannot change ports during the upgrade. For information on required ports, see Required Ports for vCenter Server and Platform Services Controller.
vCenter Server services are no longer deployed separately from vCenter Server. Separately deployed 5.5 services are upgraded and migrated to the vCenter Server virtual machine or physical server during the upgrade process. For details on service migration, see Distributed vCenter Server 5.5 for Windows Services Relocation During Upgrade or Migration and Example Upgrade Paths for vCenter Server version 5.5 to version 6.5.
The installer automatically migrates the database from Microsoft SQL Server Express to the PostgreSQL database that is included in vCenter Server. For information about migrating from Microsoft SQL Server Express to Microsoft SQL Server before upgrading to vCenter Server 6.5, see the VMware knowledge base article at http://kb.vmware.com/kb/1028601 and the Microsoft documentation. To upgrade without migrating to the PostgreSQL database, see the VMware knowledge base article http://kb.vmware.com/kb/2109321.
