New passport while in Thailand, transfer expired visa?

[maskedman2]

I just got a new passport while in Thailand. Before this I was on a tourist visa which is expired. 

 

Do I need to transfer the visa or do anything at immigration, or just exit the country holding both passports?
 

I am exiting to Savannaket, Laos.

 

Thanks

You can show both passports on departure from the country.
