Target System
n
Your target system must meet specific software and hardware requirements for
vCenter Server Appliance. See System Requirements for the New vCenter Server Appliance and
Platform Services Controller Appliance.
n
When you use Fully Qualified Domain Names, make sure that the machine you use for deploying the
vCenter Server Appliance and the target ESXi host or vCenter Server instance are on the same DNS
server.
n
Synchronize the clocks of all target virtual machines on the vSphere network before beginning
migration. Unsynchronized clocks might result in authentication problems and can cause the
migration to fail or prevent the vCenter Server services from starting. See Synchronizing Clocks on
the vSphere Network.
Pre-migration Checks
When you migrate vCenter Server, vCenter Single Sign-On, or Platform Services Controller on Windows
to an appliance, the installer does a pre-check, for example, to verify that enough space is available on
the virtual machine or physical server where you are migrating, and verifies that the external database, if
any, can be successfully accessed.
Source Environment Checks
When you migrate vCenter Single Sign-On (version 5.5) or Platform Services Controller (version 6.0),
vCenter Single Sign-On is included as part of the Platform Services Controller. When you provide the
information about the vCenter Single Sign-On service, the installer uses the administrator account to
check the host name and password, to verify that the details of the vCenter Single Sign-On server you
provided can be authenticated before proceeding with the migration process.
The pre-migration checker performs checks for the following aspects of the source environment:
n
vCenter Server, Platform Services Controller, or vCenter Single Sign-On version to verify that
migration is supported
n
SSL certificates validity and compatibility with system names
n
Network connections
n
DNS resolution
n
Internal and external ports used
n
External database connectivity
n
Administrator privileges on the Windows machine
n
Required disk space for exporting configuration data
n
NTP server validation
n
Any credentials that you enter
