Insufficient disk space on datastore when trying to migrate VM to different local storage on ESXi host.

I am trying to move a VM to another local datastore on an ESXi host and i am getting insufficient disk space even though there is enough free space. So i tried to move another VM that used MORE space and it didn't give me the error. I have attached some screen shots. W2k8temp is the orginal one i tried to move and go the error.

But what is the size of the actual hard disk of the VM? If it's greater than the allocation size of your new datastore, then yes, you'll get that error.

Rt-click on the VM -> Edit Settings, select Hard Disk and provide a screenshot of the "provisioned size"...

you are not migrating a thin disk on nfs to vmfs datastore, and its creating a thick disk?

provisioned storage or used storage? If it goes off of provisioned storage then yes it is bigger. I have attached screen shots of the VM's and datastores.

Provisioned, yes. So, if you created a "thick" disk for your VM and it's say 80GB, and your DS is 65GB, then you'll get the error you're getting...

Create a thin disk or increase datastore space.

They are all thin.
