Verify that all components of your environment are ready to upgrade vCenter Server.
Your pre-upgrade configuration of vCenter Server services determines your post-upgrade deployment type.
- If your vCenter Server 5.5 service and vCenter Single Sign-On 5.5 service are deployed on the same virtual machine or physical server, the installer upgrades them to vCenter Server 6.5 with an embedded Platform Services Controller instance. See About the vCenter Server for Windows Upgrade Process.
- If your vCenter Server 5.5 service and vCenter Single Sign-On 5.5 service are deployed on different virtual machines or physical servers, the installer upgrades them to vCenter Server 6.5 with an external Platform Services Controller instance. For information on the consolidation of distributed services during the upgrade, 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.
- If you have vCenter Server 6.0, your current deployment type is preserved during the upgrade.
For information on synchronizing clocks, see Synchronizing Clocks on the vSphere Network.
