misclassifed Virtual Device Node

During a recent technical support experience with VMWare, the technician repaired my vm and vmdk files; however, now I notice the VM is running a) with poor performance and b) an IDE virtual device node rather than SCSI.

Will this make a significant performance impact and can it be changed without trashing the vm?

SCSI is a faster interface, and also allows for easier expansion of the virtual disk.

e.g. you cannot extend IDE disk interfaces, they need to be converted to SCSI.

Seems odd, that VMware have missed that one, and not repaired it, and used the original controller type, I would re-open the Support Request ASAP!

Changing the interface type, can affect whether the VM will boot correctly.
