Can I Transfer My Education Visa to a Different School Without Leaving Thailand?

I did this last year for my daughter (note: this was a different time!) the two schools worked together and got the dates right because I had to move from north to the south of the country too. What nobody told me is that this is not a swap but a whole new application for extension so you need to meet all requirements like proof of residence, money and so on; if you had a multiple entry permit it will be cancelled.

Just be aware of this! and as stated above make sure the new school has all the paperwork done!

I cancelled my extension of stay on Tuesday after all parties (uni and imm) confirmed that this was possible. Went to get the new extension yesterday with all the required docs from the new uni.. Just to be told by imm that they can't do it. So now I have already cancelled extension A and unable to get extension B in country and will be on amnesty as of next week with classes starting Wednesday. No idea what to do.

Make 7% sure that they will do it before you cancel your current extension to prevent my current mess. 100% confirmation from all parties was not enough. (My 2 universities are in two different provinces though)

No, you got your Extension of Stay based on the course you follow with documents from the School and Ministry of Education,

You can not just swap schools,
