Is a reentry permit and NON-B visa still valid if my passport is renewed while overseas, and can they be transferred to the new passport?

When a passport is renewed while overseas, the reentry permit and NON-B visa in the old passport remain valid. To reenter Thailand, it's necessary to present both passports: the old one containing the visa and reentry permit, and the new one. Upon returning to Thailand, one can apply at the immigration office to transfer the validity from the old passport to the new one, while ensuring that the pages with valid permits are not voided.
