5- Select the partitioning options. You can likewise use the full disk space or you can choose to create a smaller partition and leave some free space. You also need to choose the VMFS version, which in my case was either VMFS 5 or VMFS 6.

Following e the original datastore was on VMFS 6, I kept the value the same for the increased storage and then click next.
