If you change the image of an instant-clone desktop pool, the image publishing operation starts
immediately. In View Administrator, the summary page for the desktop pool shows the state for the
pending image as Publishing - Infrastructure Change.
If you change the cluster of an instant-clone desktop pool, new replica and parent VMs are created in the
new cluster. You can initiate a push image using the same image to have new clones created in the new
cluster. However, the template VM, which is used in the cloning process, remains in the old cluster. You can
put the ESXi host that the template VM is on in maintenance mode but you cannot migrate the template VM.
To completely remove all infrastructure VMs, including the template VM, from the old cluster, you can
initiate a push image using a new image.
Modifying Settings in an Existing Desktop Pool
After you create a desktop pool, you can change certain conguration seings.
Table 101. Editable Settings in an Existing Desktop Pool
Configuration Tab Description
General Edit desktop pool-naming options and storage policy management seings. Storage policy
management seings determine whether to use a Virtual SAN datastore. If you do not use
Virtual SAN, you can select separate datastores for replica and OS disks.
N For View Composer linked clones, if you change to using Virtual SAN, you must use a
rebalance operation to migrate all virtual machines in the desktop pool to the Virtual SAN
datastore.
Desktop Pool

Edit machine seings such as the power policy, display protocol, and Adobe Flash seings. In
Horizon 7.0, power policy is not supported for instant clones.
Provisioning

Edit desktop pool provisioning options and add machines to the desktop pool.
This tab is available for automated desktop pools only.
vCenter  Edit the virtual machine template or default base image. Add or change the vCenter Server
instance, ESXi host or cluster, datastores, and other vCenter features.
The new values only aect virtual machines that are created after the seings are changed. The
new seings do not aect existing virtual machines.
This tab is available for automated desktop pools only.
Guest Customization If Sysprep was selected, you can change the customization specication. In Horizon 7.0, Sysprep
is not available to instant clones.
If QuickPrep was selected, you can change the Active Directory domain and container and
specify the power-o and post-synchronization scripts.
If ClonePrep was selected, you can change the Active Directory container and specify the power-
o and post-synchronization scripts. You cannot change the domain.
N For instant clones, if you change the power-o or post-synchronization script name, or
their parameters, and the new script exists in the current image, the new script is executed and
the new parameters are used when a new clone is created. If the new script does not exist in the
current image, you must select or create an image that has the new script and do a push image.
For View Composer linked clones, if you change the power-o or post-synchronization script
name, the change applies at the next recompose operation. However, changes to the power-o
script parameters or the post-synchronization script parameters do apply to the clones that are
created with the current snapshot.
