Installation guide

4 On the source machine, stop the VirtualCenter service by selecting Start > Control Panel > Administrative
Tools > Services > VMware VirtualCenter Server.
5 On the destination machine, start the vCenter Server 4.0 installer.
6 When prompted by the installer, select the DSN that you configured on the destination machine.
The Database Upgrade wizard upgrades the database tables to make them compatible with vCenter
Server 4.0. If you are upgrading from VirtualCenter 2.0.x, you must complete the Database Upgrade
wizard. If you are upgrading from VirtualCenter 2.5, the Database Upgrade wizard runs in the
background.
The legacy VirtualCenter data is preserved and the database schema is upgraded to make it compatible with
vCenter Server 4.0. After the schema is upgraded, the database is not compatible with previous versions of
VirtualCenter.
