The vCenter Server migration wizard prompts you for the deployment and migration information when migrating a vCenter Server instance, a vCenter Single Sign-On instance, or a Platform Services Controller 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 vCenter Single Sign-On or Platform Services Controller from Windows to an appliance.


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
