You can update
Horizon Composer linked-clone desktop machines, reduce the size of their operating system data, and rebalance the machines among datastores. You also can manage the persistent disks associated with linked clones.
Reduce Linked-Clone Size with Machine Refresh A machine refresh operation restores the operating system disk of each linked clone to its original state and size, reducing storage costs.
Update Linked-Clone Desktops You can update linked-clone virtual machines by creating a new base image on the parent virtual machine and using the recompose feature to distribute the updated image to the linked clones.
Rebalance Linked-Clone Virtual Machines A rebalance operation evenly redistributes linked-clone virtual machines among available datastores.
Manage View Composer Persistent Disks You can detach a View Composer persistent disk from a linked-clone virtual machine and attach it to another linked clone. This feature lets you manage user information separately from linked-clone virtual machines.
