Shrink vmdk without additional storage space ESXi5.1

Hi Guys,
We have a VM running under ESXi5.1 with a second vmdk (so NOT the system disk) which has been defined way too large.
As we now need some of this "wasted" space back, I followed the excellent instructions in the following article:

https://www.experts-exchange.com/articles/12938/HOW-TO-Shrink-a-VMware-Virtual-Machine-Disk-VMDK-in-15-minutes.html

All went well until I realised that the article says that we need to migrate/copy the VM to another datastore.. Hmm.. I only have 1 datastore and it's too full to allow a copy of this entire VM..

Is it necessary to copy the entire machine? Could I just copy the 1 vmdk?
Secondly, does it really need to be a separate datastore, or just another directory?
Do we actually need to copy/migrate it at all? (Someone in the comments of the other thread suggested that a simple reboot of the machine reduced the reported disk capacity after making the necessary edits).

Thanks in advance.
Chris

Many thanks for your replies Guys..

@Andrew: neither VCenter nor VMWare Converter are available :(

@Mr Tortur: that sounds like a good plan, thanks.

Maybe I worded my question a little badly - it is more a question whether a move/copy of the entire VM was necessary, whether I could just copy the vmdk (and then copy it back) or if indeed a copy/move is at all necessary :)

Thanks,
Chris
