You can move the virtual machines in a linked virtual machine group between datastores and save storage. The contents of the delta disk might not be as important as the contents of the base, and you can save storage by removing the delta disk.
For more information, see Creating a Linked Virtual Machine from a Snapshot.
Relocating a Linked Virtual Machine
relSpec = new VirtualMachineRelocateSpec() relSpec.diskMoveType = VirtualMachineRelocateDiskMoveOptions.moveChildMostDiskBacking relSpec.datastore = localDatastore myVm.Relocate(relSpec)
You can relocate multiple linked virtual machines to a new datastore, but keep all shared storage during the relocation. To achieve the relocation, relocate the desired virtual machines one by one, giving the option to allow reattaching to an existing disk, as shown in Relocating Multiple Linked Virtual Machines.
Relocating Multiple Linked Virtual Machines
relSpec = new VirtualMachineRelocateSpec() relSpec.diskMoveType = VirtualMachineRelocateDiskMoveOptions.moveAllDiskBackingsAndAllowSharing relSpec.datastore = targetDatastore myVm.Relocate(relSpec)
