Go to the special exchange counter without an appointment, expect a wait, and pay by card only.
Bring your identity document, current licence and a printed biometric photograph. If identifying yourself with a passport, bring a current residence-registration certificate too. If the licence was issued elsewhere, ask about the issuing authority’s record extract. The exchange costs €34.70; confirm any different procedure or extra expense before paying.
