Transfer of stamps not required in your situation. Just fly with both passports. Be mindful that at airport on return flight show reentry permit in old pp at check in. On arrival Thailand have your pp opened at reentry page. Obviously check that the io stamps you in to expiry date of reentry date.

That will only give you visa exempt entry. What is current status. Meaning how did you enter Thailand and how many days remaining on current permission of stay.

I don't understand what they are telling you. With a bank book in place your should be able to enter visa exempt and apply virtually straight away for a non O with a TM87 and required funds in bank account. Regards asking about border bounce, I don't follow.... They mentioned "obtain a tourist visa" that's not a border bounce. Tourist visa is obtained in Thai consulate/embassies.

If he has not used 30 day extension to visa exempt entry then go to immigration with a TM7 and 1900b. (also TM30 and basic photocopies of pp)

The suggestion I made re flying was down to OP ruling out minivans and also stated BKK to Udon Thani was too expensive. (It's under 2k return) For folk without significant recent history in Thailand, I often suggest mini holiday to Saigon. The OP stated that his plan was to go to Da Nang. Don't know why changed that plan. The OP favours train. The fastest express train to Nong Khai is approx 9hrs one way. More than flight BKK to Melb Oz No Thanks

What you are referring to is that without a visa some airlines may wish to see onward flight.

Application for a non O visa requires proof money from abroad. Money in bank for extensions does not need to be shown came from abroad. Yes you can use two bank accounts. There needs to be activity every month at some offices. OR Provide 12 months of bank statements. OR You use an FD account Application for non O in Thailand from visa exempt or tourist visa only needs to be in bank on day of application.

I stated... "Which office will you be using? Reason being that I'm well aware Jomitien requires two months seasoning for non O application. I'm not about to qualify every post I make re non O or whatever with exceptions to the rules. Jomitien plays its own games.

From OP..., ".....so it will be Chachoengsao Immigration Office"

Which immigration office? That should not be required. When you obtain a passport renewal the details of the non O are transferred

Which office will you be using? BTW in the links posted you will notice TM87. That is part of application for obtaining non O from visa exempt entry

Not completely clear where you are. If in Thailand you can do a border bounce enter visa exempt and apply for non O at your local immigration office. Yes you could then obtain 60 day extension to visit wife however not required. You can obtain the non O immediately at local Thai immigration office if you have Thai bank account in your name only.

You have not read the thread link I posted. For money in the bank method to apply for non O based on marriage or retirement only needs to be in Thai bank account in your name only on day of application. That will give you a 90 day stamp. In last 30 days of that permit with funds having been in bank for 2 months you can obtain 12 month extension

It is possible to enter visa exempt and apply at local immigration office for non O based on marriage and subsequent 12 month extension. Why need extra 60 day extension to visit wife? Process outlined in this thread https://aseannow.com/topic/1315828-visa-exempt-to-90-day-non-o-spouse-visa-conversion-in-thailand/

Never suggested he could. He is returning to USA. His current permission of stay is gone also the non O obtained from agent. He plan is to reenter Thailand visa exempt and obtain a non O at immigration office with 800k in Thai bank (his own funds). After 2 months seasoning of the 800k he will obtain the subsequent 12 month extension.

It's unfortunate that surprises can occur. I recently had my stamps transferred to new pp and CW requested photocopies of all pages of bank book and account update. This has never been a requirement. Doesn't Samut Prakan have photocopy stall?

Earlier I asked ...... "During this current extension did you maintain the financial requirements? That's a yes or no." OP Reply....... "No I did not"

The OP is very unclear. Confirmed that current extension was agent assisted (didn't meet financial requirements) Perhaps does not realize that an agent can obtain another extension. Mentions is OP mentions 800k in Thai bank. Perhaps aim is to provide the financials and do it all himself. If that's the case he would need start over. Who knows

That will work. Here is thread that explains the process. Also contains links. Do you have Thai bank account in your name only? https://aseannow.com/topic/1311886-visa-exempt-to-retirement-extension-process-and-cost/

So your plan is to do border bounce and obtain a visa exempt 30 day stamp. You stated in couple of replies... "I don't want to use minivan." That would have helped in the OP. Fly Bangkok to Udon Thani and short run to friendship bridge.

You need to be aware of you "enter before date" on your visa. That sets when you need to exit and reenter Thailand to obtain another 60 days

Also some offices require home visit.

How....think you mean you switched extension based on retirement to based on marriage.
