When renewing a passport in Thailand, do you need to transfer the entry stamp to a new passport?

I posted about this, search passport and it will come up

The only situation in which you need to transfer the entry stamp to your new passport is when you need something at an Immigration Office like 90 day reporting or residence certificate.

All other situations having both passports is OK

Just came in on a new passport. No questions asked. As if it happens every day.

I did this recently.

I took old and new passport to immigration when I was leaving Thailand. Explained to the IO. They took me around until they found a senior IO. They stamped out my new passport and wrote some stuff on the stamp. When entered I showed both passports, took a bit longer than normal, made me nervous, but was totally fine. You always have to arrive with both passports - which means I’ll leave with both. I haven’t left again since then, so not sure if they will need to check on way out.

The issue with a DTV is there's really nothing to transfer other than an entry stamp. Just carry both passports for the duration of the visa

I bring my old passport every time I go to Thailand. Just in case

We had to go to immigration and have the stamp transferred. We have also been asked to show the old passports even though it has been over a year since we transferred the stamp and we’ve exited/entered with the new ones. I recommend keeping them with you just in case.
