Use VMware Converter for this, it will let you re-size the drives. Cloning is only a feature if you have VirtualCenter. If you do not you can use Converter or vmkfstools to clone a VM.

You can use vmkfstools with ESX3. To expand the size of the disk use
vmkfstools -X 130G vmname.vmdk

However this only increases the virtual disk size, not the partitions on that disk. You'd need something like gparted or similar tools to achieve that.

If you're using Converter you should be able to increase the size when you migrate the VM.

You can use the methods I provided in the link above or run Converter to clone the VM and increase the disk size to 130GB. Using Converter will essentially create another VM with the new larger disk size. You could then delete the original VM.
