Traveling with Thai Visa in Cancelled Passport

[Jadam]

A friend of mine is in the middle of some traveling and she's had to get a new passport.  She still has a valid visa extension in the cancelled passport that she's carrying with her (as well as the new passport).

 

Can she only transfer the visa to her new passport at the same immigration office that issued the extension?

If she does a stopover in Thailand on a weekend, goes to another country, then returns to Thailand in a few weeks will that cause any issues?

I'd appreciate any help from someone who has similar experience.

Thanks.

Visas are not transferred to a new passport. Immigration can only transfer stamps they have done in the old passport.

If on a long stay extension the stamps can only be transferred at the office where it was issued.

She will not have a problem using both passports to use the re-entry permit in her old passport when entering the country. She will need to show both passport until she gets the stamps are transferred.
