hello all, i am looking at moving from the UK and have a question regarding 3rd pillar pensions in switzerland - as far as i see maximum annual contributions are CHF 6k but i have a already quite large uk pension i would like to port to switzerland - have the following questions:

can i move my uk private pension over to switzerland and if so is it 3rd pillar equivalent?

if 3b is it subject to any tax in switzerland upon moving?

can it be used in the usual swiss pillar 3 way to buy primary residence property

is there a maximum size that can be transferred into a scheme? if so how much?

many thanks in advance for any help recieved on this as have been surfing for days and can find clarification.
