No, what they are saying is that you will need to create a new Virtual Disk, which is empty, afterwards you will need to take the backup of the data from the original Virtual Disk and then you need to restore the data to the new Virtual Disk you created. 
Is it possible to take my PE setup and migrate the disk drive to SSD. It is a PE T320 with a PERC H310 raid controller. The HDD is setup as two clone drives and I wish to move the data to 2 SSDs.
