You can performance maintenance on hosts where instant clones reside by putting the ESXi hosts into maintenance mode. You can use vSphere Web Client to put the ESXi host into maintenance mode.
Starting with Horizon 7 version 7.13, before putting the ESXi host into maintenance mode, you can disable the instant clone parentVM so that VMware Update Manager can update the ESXi hosts. If you disable the parentVM, Horizon 7 will automatically delete the parentVM so that the host can go into maintenance mode without any manual intervention. Any new instant clones are then provisioned without the parentVM. Horizon 7 does not use Smart Provisioning on instant clones configured with vTPM. To selectively disable parentVMs in a cluster, see the KB article 80369.
Instant clones configured with NVIDIA GRID vGPU can vMotion to another host without losing any functionality.
To use the instant-clone utilities, see Instant-Clone Maintenance Utilities.
