When you migrate the VMware Horizon View Composer service, you can also migrate the View
Composer database to a new machine.
Whether or not you migrate the View Composer database, the database must be configured on an
available machine in the same domain as the new machine on which you install the VMware Horizon
View Composer service, or on a trusted domain.
View Composer creates RSA key pairs to encrypt and decrypt authentication information stored in the
View Composer database. To make this data source compatible with the new VMware Horizon View
Composer service, you must migrate the RSA key container that was created by the original VMware
Horizon View Composer service. You must import the RSA key container to the machine on which you
install the new service.
If the current VMware Horizon View Composer service does not manage any linked-clone virtual
machines, you can migrate the service without using the existing View Composer database. You do not
have to migrate the RSA keys, whether or not you use the existing database.
Note Each instance of the VMware Horizon View Composer service must have its own View Composer
database. Multiple VMware Horizon View Composer services cannot share a View Composer database.
Migrate View Composer with an Existing Database
When you migrate View Composer to another physical or virtual machine, if you intend to preserve your
current linked-clone virtual machines, the new VMware Horizon View Composer service must continue to
use the existing View Composer database.
Follow the steps in this procedure when you migrate View Composer in any of the following directions:
n
From a vCenter Server machine to a standalone machine
n
From a standalone machine to a vCenter Server machine
n
From a standalone machine to another standalone machine
n
From a vCenter Server machine to another vCenter Server machine
When you migrate the VMware Horizon View Composer service, you can also migrate the View
Composer database to a new location. For example, you might need to migrate the View Composer
database if the current database is located on a vCenter Server machine that you are migrating as well.
When you install the VMware Horizon View Composer service on the new machine, you must configure
the service to connect to the View Composer database.
