The vCenter Server migration wizard prompts you for the deployment and migration information when migrating a vCenter Server instance or a vCenter Single Sign-On instance from Windows to an appliance. It is a best practice to keep a record of the values that you entered in case you must power off the appliance and restore the source installation.

You can use this worksheet to record the information that you need for migrating a vCenter Server instance with an embedded vCenter Single Sign-On, vCenter Server instance with an external vCenter Single Sign-On, or an external vCenter Single Sign-On from Windows to an appliance.

Important: The user name that you use to log in to the machine from which you want run the GUI installer, the path to the vCenter Server Appliance installer, and your values including the passwords, must contain only ASCII characters. Extended ASCII and non-ASCII characters are unsupported.

Local OS users existing on source Windows machine are not migrated to the target vCenter Server Appliance and must be recreated after migration is complete. If any local OS user names are used to log in to the vCenter Single Sign-On, you must recreate them and reassign permissions in the Platform Services Controller appliance.

If the source vCenter Server machine is joined to an Active Directory domain, the account you use must have permissions to rejoin the machine to the domain. For more information, see http://kb.vmware.com/kb/2146454

The options vary depending on the size of your vSphere environment.

  • Tiny (up to 20 hosts, 400 virtual machines)
  • Small (up to 150 hosts, 3,000 virtual machines)
  • Medium (up to 300 hosts, 6,000 virtual machines)
  • Large (up to 1,000 hosts, 10,000 virtual machines)

Join or do not participate in the VMware Customer Experience Improvement Program (CEIP).

For information about the CEIP, see the Configuring Customer Experience Improvement Program section in vCenter Server and Host Management.

Join the CEIP
Temporary network for communication between the source vCenter Server or vCenter Single Sign-on and the target vCenter Server Appliance
Important: The
IP address or port group of the temporary network must be on the same subnet as the source vCenter Server or vCenter Single Sign-on. Verify that the default gateway, IP address, and subnet mask match with the port group that you select. The port group that you select should be able to acquire the source vCenter Server or vCenter Single Sign-on IP address.
IP address version IPv4
IP address allocation method Static
Static assignment settings Network address
Subnet mask
Network gateway
Network DNS servers, separated with commas
Enable or disable SSH Disabled by default
