If you mean can you go from thick to thin - yes you can see below

A few options exist

1. Storage vMotion the Virtual Machine to another datastore, and select Thin Provision Disk, in the options.

2. Storage vMotion or Migrate to a NFS datastore (which supports Thin disks only), the VM will be thin provisioned.

3. Create a V2V using VMware vCenter Converter Standalone.

see my EE Article

4. using the command line tools vmkfstools

e.g. vmkfstools -i SERVERNAME.vmdk -d thin thinSERVERNAME.vmdk

Will this work for ESX 4.1 also?
