A Windows VM hosted by a VMware ESXI 6.5 (member of a vSphere 6.5 infrastructure) has a VMDK disk whose size is 400 GB and whose format is thin.
The VMDK disk contains a partition whose size is 200 GB.
How can I reduce the size of the VMDK disk to, let's say, 300 GB?

you can't just change the size of the VMDK, if you want to decrease the virtual disk size only thing that is supported is using VMware Converter, which basically means you create a second VM with a new disk size.
Hello,
Based on my experience and specially with VMware, technicalyyou can shrink the disk through a specific process but really this mission is very critical.
And as mentioned by my colleagues the recommended/safe way is to use VMware Converter.
Many thanks for the answers.
I made a test with VMware Converter with another (similar) VM but I found some critical issues:
Given that there is no other solution, is there any way to ensure that the cloned VM is as similar as possible to the original one?

When you need to reduce the size of a VMDK with Converter you only run Converter against the vmdk - that means you pretend to convert the VM but actually throw away the new vmx-file and just replace the resized vmdk.
The problems you mentioned are the typical result of using Converter but then NOT discarding the new vmx-file.

That page I wrote recently shows how to cut a vmdk from cli - make sure you dont use that approach if you dont match the start conditiions !!!!
