Preparing vCenter Server Certificates for Migration
You must verify that your vCenter Server certicates are prepared before you start the migration process.
Certificate Files Location
The vCenter Server certicate les are located at %ProgramData%\VMware\VMware VirtualCenter\SSL
Supported Certificate Types
If your environment uses any of the supported certicate types, you can continue with the migration. The
migration process proceeds normally and preserves your certicates.
n
Your rui.crt le contains the entire chain including the leaf certicate. You can create this type of
certicate by deploying and using the VMware SSL Certicate Automation Tool,
seehp://kb.vmware.com/kb/2057340.
n
Your rui.crt le contains the leaf certicate and the corresponding cacert.pem is available to validate
the rui.crt.
Unsupported Certificate Types
If your environment uses any of the unsupported certicate types, you must prepare your certicates before
you can proceed with the migration process proceeds.
n
Your rui.crt contains only the leaf certicate, the cacert.pem is missing or invalid, and cacert.pem is
not added to the Windows trust store.
Get the Certicate Authority certicate, including all intermediate certicates, and create a cacert.pem
le, or replace the vCenter Server certicates with any of the supported formats.
n
Your rui.crt contains only the leaf certicate and the cacert.pem is missing or invalid, but the
cacert.pem is added to the Windows trust store.
Get the Certicate Authority certicate, including all intermediate certicates from the Windows trust
store and create cacert.pem. Use OpenSSL to verify the certicate by running verify -CAfile
cacert.pem ru.crt command
For more information about vSphere security certicates, 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.
