Moving from Trading212 trading account to ISA

Good after, I wanted to confirm that my understand of CGT is correct. In the 23/24 tax year, I have been buying and selling shares in a normal Trading 212 account (i.e. non-ISA account). If on the last day of the tax, 5 April 2024, I sell all my shares, and then on the first day of the tax year for 24/25 (i.e. 6 April 2025) I transfer my funds to a Trading212 ISA account, and buy the same quantity of shares but in a Trading 212 ISA account, does that mean: 1. for Tax year 23/24 I should pay capital gains tax on all realised gains achieved in my normal (non-ISA) Trading212 account, 2. for Tax year 24/25 I would not have to pay any capital gains tax on the shares I buy and sell in the Trading212 ISA account (deposit limit of £20,000). I wanted to check my understanding above was correct. Thank you

Hi anderssummers,
That is correct.
Thank you.
