Anyone gone from a regular SIM to a Micro-SIM?

Several months ago when the wife and I bought Samsung S4's at a DTAC service center the DTAC rep took the miniSIMs from our Samsung Ace 2's, stuck then in an adapter he had plugged in the USB port of his computer, copied the contents, removed the miniSIMs, then put in the new microSIMs to be used in the S4s and copied the info to the microSIMs. Both our SIMs had some contact info stored on the SIM (not just stored only on Google severs)....basically the DTAC rep made a mirror copy from the miniSIM to the microSIM, activated the new microSIMs with our same numbers for the new mobile data plan we also bought, and off we went. I figure if your phone can save contact data to a SIM a similar device in a computer with the right software/utility can also.

Edit: Oh yea, it was free...I sure hope so since we bought the S4's from them.
