PMJI: you can do this with Veeam, use trial if you didn't buy. Backup VM. Restore VM, specifying different settings, and then select different datastore for the disk in question.

I'm afraid that you can't use the GUI for this, due to the limitation of you licensed edition.
There are other option which however require downtime (VM powered off).
One of them is to migrate/clone the virtual disk from the command line, and to attach the cloned disk to the VM.
Assuming the the target is the RAID6 datastore, and no "NG" folder already exists on this datastore, the following commands could be used:
mkdir "/vmfs/volumes/Storage-7.2K-RAID-6/NG"
vmkfstools -i "/vmfs/volumes/Storage-10K-RAID-10/NG/NG.vmdk" "/vmfs/volumes/Storage-7.2K-RAID-6/NG/NG.vmdk" -d thin
Note: "-t thin" is optional, and depends what you want/need.
Once cloned, make note of the virtual disk's SCSI-ID (in the VM's settngs), remove (don NOT delete from disk yet) the virtual disk from the VM's settings, save the configuration, then re-open the the settings again and attach the cloned virtual disk using the original SCSI-ID.
Before powering on the VM, I'd suggest that you rename the original virtual disk's folder to e.g. "NG-old".
If everything (VM, backup) works as expected, you may then delete the old virtual disk.

Hi all.
I have a VM with 2 hard disks (2 partitions), one hard disk is for Windows System and the other one is for Data. The first hard disk is part of a data storage and the second hard disk is part of another data storage.
Now, I want to move the second hard disk from the current data storage to another one, because I don't have enough space for snapshots, Veeam B&R won't run too because of that, not in the best situation right now. What is the easiest and safest method to accomplish? Using vSphere client or vCenter? This is my first time doing it. Just need one disk from the VM to move, not the entire VM.
In the Migrate option (change storage only) I don't see option to move only one hard disk.
Thank you.
