Who do you go to if you have new passport , but old Thai visa in old passport.... English passport.

Hi Guys. I have a new British passport and need to transfer visa, etc over from the old passport. I’m wondering if anybody has done that recently? Thai Immigration list their needs, including (1) Copy of former passport with your photo (2) Copy of new passport with your photo. I would take that to mean photocopy of the picture page of each passport. So far so good and all affirmed by Richard Barrow’s 2019 article. But then Richard Barrow mentions photocopy also needed of every stamped page of the old passport. Nothing in the Thai Immigration form suggests that, so I am wondering if that has been abandoned or quite what? Also at Land Transport any surprises when you came to change your Thai driver’s licence for a new one endorsed with the new passport number?

Thai Consulate Vientiane. I know I need to book an appointment ahead of visiting.

I am waiting on the arrival of a new passport. It should arrive before Songkran, but it may be delayed by the holidays.

Question: Can I make the consulate appointment with my *old* passport number and use the email confirmation plus the old, canceled passport to enter the Thai Consulate and then apply for a visa in my new passport?

From my understanding, your passport number must match the email confirmation. If I provide all of this evidence, will common sense prevail?

Thanks in advance for your help.

If you arrive at Bangkok Airport with a brand new passport (having got a new passport while back home), do you enter the new passport details on the TM6 card, even though your Extension of Stay stamp and Re-entry permit are in the old (cancelled) passport? I understand that both passports need to be presented to the IO, but confused about which number to use on the Arrival card.
