@Jeremy ****
how about you just quit while you're behind ๐ฎ
One final time you cannot transfer a VISA sticker or eVisa PDF to a new passport, you can get EXTENSIONS OF STAYS transferred at the immigration office ONLY.
IF you have a sticker DTV visa in your passport you ARE obligated to carry BOTH passports to stamp in and out for the duration of the visa (that would be for the next 5 years ๐ฎ ).
Where as IF you have an eVisa PDF print out AND you got your new passport inside thailand you do exactly as I said.
You EXIT showing BOTH passports (because your entry stamp is in the old one), you cannot go thru the eDeparture gates if you got a new passport inside the country either you got to the officers and get hard stamped out. They will stamp you out on the new passport and note that you entered on the old passport
THEN
to get back in to the country all you need is copy of the data page of your passport, the last entry stamp from it (the one that goes WITH the new exit stamp in the new passport) the print out of the DTV visa and your new passport.
