Slice the virtual hard disk of a VMware vSphere 6.7 virtual machine using VMware vCenter Converter Standalone

In the list of conversion options that appears, click on the "Data to copy" option.

In the "Data copy type" list, select the "Select volumes to copy" option.

Next, click on the "Advanced" link that appeared to the right of the "Data copy type" list.

Go to the “Destination layout” tab and click the “Add disk” button.

As you can see at the bottom of the table, a new virtual hard disk (VirtualDisk) has appeared.
Now, select the partition you want to move from the 1st virtual hard disk to this new virtual hard disk and click the "Move down" button.
In our case, it is partition "E" whose size is 48 GB.

As you can see, the partition will be moved to the new virtual hard disk.
The maximum capacity of the 1st virtual hard disk will therefore be reduced to correspond to the capacity necessary for the remaining partitions thereof.

For the type of provisioning to use, select the desired value for each virtual hard disk in the "Type/Cluster" column:

• Thick: static provisioning = pre-allocated disk space.
• Thin: thin provisioning = disk space NOT pre-allocated.

Once you have made the desired changes, click Next.

A summary of the conversion parameters used appears.
Click Finish to start converting the desired virtual machine.

The message "Submitting job" appears for a few seconds.

Then, the conversion task (Convert virtual machine or backup image) appears.
Note that the estimated remaining time displayed is higher than reality for the first few percent.

On your VMware vCenter Server (or VCSA), you will see a “Create virtual machine” task appear in recent tasks.

In the conversion history, you will be able to see:

• Starting block-level cloning for volume 'X:': copy of the partition indicated in apostrophes.
• Updating the boot sectors on the destination machine: updating the boot sector on the destination virtual machine so that it can continue to boot correctly on the guest operating system installed there.
• Updating BCD on the destination machine's system volume: updating the boot menu (BCD) of the guest operating system (Windows).
• Updating drive letters for the destination volume layout: updating the partition letters for the destination partition tables.

Finally, VMware vCenter Converter Standalone will perform reconfigurations (as usual), then the conversion task status will change to "Completed" if it completes successfully.

3. Converted virtual machine

Select the new virtual machine in the web interface of your VMware vCenter Server (or VCSA) and deploy the “VM Hardware” block.
As you can see, the new original virtual hard drive (which was 80 GB in our case) has been cut in 2.
Now, your virtual machine has 2 virtual hard disks instead of one.

Start the new virtual machine and it starts without problems.

The virtual machine is still working.
