Do I Need to Transfer a Visa Exempt Extension to My New Passport in Thailand?

After renewing your UK passport, it's unclear whether you need to transfer your visa exempt extension stamp from your old passport to the new one. Community feedback suggests that you may simply need to carry both passports upon exiting Thailand, as one member advised showing both passports to avoid issues. However, there is also a recommendation to visit immigration to confirm the specifics, especially if you have an extension of stay stamp.
