I solved this problem. First i renamed OLD VM, and converted it to NEW VM to a different data storage both data disks C and D. After that i moved OLD VM's D drive out on SSD data storage and moved NEW VM's D drive to SSD storage using vCenter Migration tool.
In this link you can see how to use vCenter MIgration Tool, to move disks.
