Migrate View Composer with an Existing Database on page 99
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.
n
Migrate View Composer Without Linked-Clone Virtual Machines on page 100
If the current VMware Horizon View Composer service does not manage any linked-clone virtual
machines, you can migrate View Composer to a new physical or virtual machine without migrating
the RSA keys to the new machine. The migrated VMware Horizon View Composer service can
connect to the original View Composer database, or you can prepare a new database for View
Composer.
n
Prepare a Microsoft .NET Framework for Migrating RSA Keys on page 101
To use an existing View Composer database, you must migrate the RSA key container between
machines. You migrate the RSA key container by using the ASP.NET IIS registration tool provided
with the Microsoft .NET Framework.

Migrate the RSA Key Container to the New View Composer Service on page 102
To use an existing View Composer database, you must migrate the RSA key container from the source
physical or virtual machine on which the existing VMware Horizon View Composer service resides to
the machine on which you want to install the new VMware Horizon View Composer service.
Guidelines for Migrating View Composer
The steps you take to migrate the VMware Horizon View Composer service depend on whether you intend
to preserve existing linked-clone virtual machines.
To preserve the linked-clone virtual machines in your deployment, the VMware Horizon View Composer
service that you install on the new virtual or physical machine must continue to use the existing View
Composer database. The View Composer database contains data that is required to create, provision,
maintain, and delete the linked clones.
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.
