Shrinking disks

I need to use VMware Converter to shrink VMs (hosted by VMware ESXi 6.5 hosts) with thin vmdk disks.

Disks are overallocated, so that a thin vmdk disk whose size is 300 GB hosts a Windows partition whose size is 100 GB.

I need to reduce the size of the vmdk disk to the same as the guest partition.

I was told that VMware Converter is the best solution to solve the problem and I made some tests with version 6.2.

I got contraddictory results as:

• The size of the vmdk disks is reduced as expected
• The VM gets a wrong IP address
• The Windows VMs need to be reactivated

Is there a way to preserve the VM configuration?

Should I use a different version of VMware Converter?

Should I use any other solution to get the same result?

Is there any way to schedule the conversion via command line?
