3 Test the connectivity.
The system now has a DSN that is compatible with vCenter Server. When the vCenter Server installer
prompts you for a DSN, select the 64-bit DSN.
Restore the vCenter Server Configuration and Install vCenter Server on the
Destination Machine
Use the data migration tool to start the vCenter Server installer and restore the vCenter Server configuration
to the destination machine.

Restore the vCenter Server Configuration and the Bundled Database and Install vCenter Server on the
Destination Machine on page 52
After you use the data migration tool to back up the configuration of a vCenter Server system with the
bundled SQL Server Express database, you complete the migration to a new machine by using the
data migration tool to install vCenter Server and restore the vCenter Server configuration on the
destination machine.
n
Restore the vCenter Server Configuration and Nonbundled Database and Install vCenter Server on the
New Machine on page 54
After you use the data migration tool to back up the configuration of a vCenter Server system with a
nonbundled database, you complete the migration to a new machine by using the data migration tool
to install vCenter Server and restore the vCenter Server configuration on the destination machine.
Restore the vCenter Server Configuration and the Bundled Database and Install
vCenter Server on the Destination Machine
After you use the data migration tool to back up the configuration of a vCenter Server system with the
bundled SQL Server Express database, you complete the migration to a new machine by using the data
migration tool to install vCenter Server and restore the vCenter Server configuration on the destination
machine.
Use this procedure if you are migrating a vCenter Server that uses the bundled SQL Server Express
database. The data migration tool restores the database to the new machine and launches the vCenter Server
installer.
If you are migrating a vCenter Server that uses a database other than the bundled SQL Server Express
database, see “Restore the vCenter Server Configuration and Nonbundled Database and Install vCenter
Server on the New Machine,” on page 54.
VMware recommends that you use the same host name for the destination machine that you used for the
source machine.
Prerequisites
n
Use the data migration tool to back up the VirtualCenter or vCenter Server configuration on machine
you are migrating from. See “Back Up VirtualCenter or vCenter Server Configuration with the Data
Migration Tool,” on page 50
n
Ensure that the destination vCenter Server machine has access to all other systems that it must connect
to, such as the domain server, Windows Active Directory server with vCenter user accounts, database
server, and license server.
n
Ensure that Microsoft Windows Installer (MSI) 4.5 is installed on the destination machine.
n
Ensure that Microsoft .NET Framework 3.5 is installed on the destination machine.
