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.
