If you’re like me, that is with a very limited cash availability to invest in hardware, you will most likely run out of space pretty fast once you start converting all those virtual machines you got on the desktop to your newly installed ESXi.
Now, you will immediately think, what happened to my thin provisioned disks that made them grow like that? You can google for the answer but let me tell you a better solution than what you will find on the net, which are:
– convert the virtual machine
– use some cdelete or whatever its name is to free up space
– maybe other things that are not as cool
The cool idea is that you can create a new disk, about the size that you need, and copy over the data to the new disk then delete the old one. Either use dd in linkux or whatever diskcopy you can find for windows (easeus has a few solutions) or use a system backup something that will pack up your files and then restore on the new disk.
This beats converting V2V as the hardware will not change.
