Clarification needed - Buying and selling on different exchanges

Investing / Brokers
1

I have two basic questions about ISINs and Exchanges.

Question 1 -: Is it possible to buy shares of a particular ISIN on one exchange and sell it on another exchange? For example -: If I buy 100 shares of VEVE (IE00BKX55T58) on LSE or XETRA , can i sell them on SIX? If yes, which currency would i actually get after selling?

Another question -: To make it more complex, is it possible to buy IE00BKX55T58 on LSE at IB and sell them at SIX (via Swissquote) after transfering them
