The vSphere Migration guide provides information about migrating VMware® vCenter Server to vCenter Server Appliance.
To move to the current version of vSphere by performing a fresh installation that does not preserve existing configurations, see the vSphere Installation and Setup documentation. To upgrade your vSphere environment, see vSphere Upgrade. For information about Migration Assistant and answers to frequently asked questions, see http://kb.vmware.com/kb/2146439.
This information is intended for anyone who plans to migrate from earlier versions of vSphere. The information is written for experienced Windows or Linux system administrators who are familiar with virtual machine technology and data center operations.
