If you are moving in from UAE to Qatar then you can exchange your UAE DL with Temporary DL here in Qatar (QR150... I suppose) as of now (if you do not have your RP done) and when your RP done get the permamnent DL by paying another QR250. No need for any test as u have UAE licence. If however u are on a visit for a few days u can continue driving with UAE licence. More info. can be had from Traffic Department.

Cheers...
