I am awaiting my passport renewal from UK and I have to travel next week. If I receive my new passport and dont have time to transfer data from old to new (2 year extension of stay from non b and multi 1 year re entry) would that be an issue leaving and coming back? Do i have to transfer stamps first?

TLDR : Answer Summary
When traveling internationally after receiving a new passport while having existing visa stamps in your old passport, it is essential to carry both passports. Present the old passport that contains the relevant entry stamps when departing and also show both the old and the new passports upon arrival in Thailand. This ensures that immigration has a complete understanding of your visa status and travel history.
