which two will be migrated by default?

When migrating a Windows vCenter Server 6.0 to the vCenter Server Appliance 6.5, which two will be migrated
by default? (Choose two.)

A.
Local Windows OS users and groups

B.
Configuration

C.
Custom ports

D.
FQDN

E.
Historical and Performance data

Explanation:
The following list contains features or actions that are currently not supported:
Local Windows OS users and groups are not migrated to the Photon OS of the vCenter Server Appliance
6.5. If you assigned vCenter Server permissions to any Local Windows OS users and groups, remove the
permissions assignments before the migration. You can re-create Local OS users and groups on the Photon
OS of the vCenter Server Appliance 6.5 after the migration.
After the migration, the source vCenter Server is turned off and cannot be turned on to avoid network ID
conflicts with the target vCenter Server Appliance. After the source vCenter Server is turned off, all solutions
that are installed on the source vCenter Server and that are not migrated become unavailable.
Migration of deployments that use custom ports for services other than Auto Deploy, Update Manager,
and vSphere ESXi Dump Collector are not supported.
The migration process migrates only one network adapter settings to the target vCenter Server Appliance. If the
hostname of the source vCenter Server resolves to multiple IP addresses across multiple network adapters,
you have the option to select which IP address and network adapter settings to migrate. You cannot add the
rest of the network adapters and settings to the target vCenter Server Appliance.
You cannot migrate a vCenter Server instance that uses a DHCP IP address.
