Best way of converting sim to microsim?

[saaby93]

If you get a new phone and want to put your old sim in it but the new phone needs a microsim, is there a way of getting another sim and copying to it?

If you cut it, surely it wont fit in your old phone and the process seems a bit final.
I found some adapters on ebay for microsim to sim but wondered if anyone knew of a way of copying sim to microsim
