Driving license exchange rules

Hello 👋 … I just moved from Europe to Dubai. I entered the UAE with the Entry Permit that RAKEZ FZ helped me get. Now I hold EID and officially a resident.

I am struggling to find clear information about how long do I have until it’s mandatory to convert the driving licence. Or whether it’s immediately upon becoming a resident.

What are the rules? Is there any sort of grace period?

Thanks for your help!
