Can I transfer my Thai visa to a new passport if my old one is clipped?

I travelled with two passports in October my visa was in my old passport but they stamped me in on my new one.

My Thai visa is in my old passport but my entry stamp is in my new passport. I travelled with both. Thai visa application and UK passport application is online now too. No need to visit embassy

Visa is not transferable. It will not be invalid once it was issued, even with the invalidation of your passport. Now, in the UK, you have to apply on the eVisa system. It will be on the system and you only get the email. So far no report is similar to your case. It should be the same as physical visa stickers (because there are countries not on eVisa system, issuing Visa stickers onto your passport), you should bring both old and new passports to travel with that visa. Your old passport is only proof the visa is yours. If you are worried about the situation, you have to apply for your visa after your new passport is issued.
