You can migrate a vCenter Server for Windows instance to a vCenter Server Appliance instance.

You can migrate a vCenter Server version 5.5 or version 6.0 instance on Windows to a vCenter Server Appliance 6.5 deployment on a Linux-based OS.

The vCenter Server example migration paths demonstrate supported migration outcomes.

You can migrate a vCenter Server instance with an embedded vCenter Single Sign-On (version 5.5) or Platform Services Controller (version 6.0) to a vCenter Server Appliance 6.5 instance with an embedded Platform Services Controller appliance. In this case the software migrates the vCenter Server instance and the embedded vCenter Single Sign-On instance or Platform Services Controller instance at the same time.

You can migrate a vCenter Server instance with an external vCenter Single Sign-On (version 5.5) or Platform Services Controller (version 6.0) to a vCenter Server Appliance 6.5 instance with an external Platform Services Controller appliance. In this case you must first migrate the external vCenter Single Sign-On instance or Platform Services Controller instance and then the vCenter Server instance.

If you have multiple systems configured for high availability, vCenter Server enables you to incorporate your common services into an external Platform Services Controller configuration as part of your upgrade process.

If you have a multi-site setup configured with replication, you can use vCenter Server to incorporate your common services into an external Platform Services Controller configuration as part of your upgrade process.
