5 Click Add.
6 In the Add NTP Server dialog box, enter the IP address or fully qualied domain name of the NTP
server to synchronize with.
7 Click OK.
The host time synchronizes with the NTP server.
Preparing vCenter Server Certificates for Migration
You must verify that your vCenter Server certicates are prepared before you start the migration process.
Certificate Files Location
The vCenter Server certicate les are located at %ProgramData%\VMware\VMware VirtualCenter\SSL
Supported Certificate Types
If your environment uses any of the supported certicate types, you can continue with the migration. The
migration process proceeds normally and preserves your certicates.
n
Your rui.crt le contains the entire chain including the leaf certicate. You can create this type of
certicate by deploying and using the VMware SSL Certicate Automation Tool,
seehp://kb.vmware.com/kb/2057340.
n
Your rui.crt le contains the leaf certicate and the corresponding cacert.pem is available to validate
the rui.crt.
Unsupported Certificate Types
If your environment uses any of the unsupported certicate types, you must prepare your certicates before
you can proceed with the migration process proceeds.
n
Your rui.crt contains only the leaf certicate, the cacert.pem is missing or invalid, and cacert.pem is
not added to the Windows trust store.
Get the Certicate Authority certicate, including all intermediate certicates, and create a cacert.pem
le, or replace the vCenter Server certicates with any of the supported formats.
n
Your rui.crt contains only the leaf certicate and the cacert.pem is missing or invalid, but the
cacert.pem is added to the Windows trust store.
Get the Certicate Authority certicate, including all intermediate certicates from the Windows trust
store and create cacert.pem. Use OpenSSL to verify the certicate by running verify -CAfile
cacert.pem ru.crt command
For more information about vSphere security certicates, see the vSphere Security documentation.
Preparing vCenter Server Databases for Migration
The vCenter Server Appliance instance requires a database to store and organize server data. Ensure your
source vCenter Server database is prepared for migration to the target vCenter Server Appliance.
Each vCenter Server Appliance instance must have its own database. The bundled PostgreSQL database that
is included in the vCenter Server Appliance supports up to 1,000 hosts and 10,000 virtual machines.
I If you are using an external database for vCenter Server Appliance, it is converted to an
embedded PostgreSQL database during the migration.
