You can migrate a vCenter Server with an external vCenter Single Sign-On to an appliance.
About this task
When you migrate from vCenter Server with an external vCenter Single Sign-On (version 5.5) on Windows to vCenter Server Appliance with an external Platform Services Controller appliance, you migrate in two steps.
First you migrate the vCenter Single Sign-On instance from Windows to an appliance.
Next you migrate the vCenter Server instance from Windows to an appliance.
Concurrent migrations of vCenter Single Sign-On instances are not supported. You must migrate the instances in a sequence. If you have multiple vCenter Single Sign-On nodes, first you must migrate all vCenter Single Sign-On nodes to Platform Services Controller appliances before you start the migration of vCenter Server to vCenter Server Appliance.
If vCenter Inventory Service, vSphere Web Client, vSphere Auto Deploy, or vSphere ESXi Dump Collector are installed on a different machine than the source vCenter Server with an embedded vCenter Single Sign-On, these components are migrated to the target vCenter Server 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.
For each node to be migrated, the installer:
Deploys a new target appliance.
Exports the required files from the source vCenter Single Sign-On instance.
Copies the required files to the target appliance for migration.
Runs the migration process on the target appliance as specified in the Summary.
Imports and updates the files and settings of the source vCenter Single Sign-On instance to the new appliance.
