What is the process for transferring a non-O multiple entry visa based on marriage to a new passport in Thailand?

Hi guys

looking for visa advise.

( shortly)

its difficult transfer visa (non-O multiple entry based on marriage ) from old passport to new one.

how is a proces?

(long version)

i planing go next month for non-O ME visa, then next month go back to my country for new passport ( coz its full)

reason why i will not do visa after with new passport well my wife is pregnant and as i count i will must solve visa or visa run at time she will give a birth ( bad timing). so i looking for a way to not move anywhere during give a birth.

and only seems to be transfer visa to new passport but well i have no idea about all that proces just thought experiences with thai paper work (like we all have xD)
