Is it normal for the Thai immigration to only require the new passport stamp when transferring from an old passport?

The original poster inquired about the process of transferring visas from an old passport to a new one after receiving their new passport from the Australian Consulate in Phuket. They were told by the consulate that the stamp from their old passport is sufficient for Thai immigration. Responses from the community agreed that in many cases, especially in Chiang Mai, the stamp alone is accepted without needing an additional letter. Users also suggested checking local Phuket immigration office procedures. Overall, the consensus indicates that this process is typically straightforward.
