CGT on RSU with profits moved to S&S ISA

I was given some RSU as part of a bonus several years ago. When given I paid normal income tax on them, so understand I could have just taken them then without any futher tax liability. They were deposited into a US account on my behalf and I just left them there. They have now grown and there would be profits if I were to sell them and spend them, which I understand would be subject to CGT. My question is : if I sell them (not able to transfer direct) and immediately buy the same shares at current value into a S&S ISA is there any CGT due? Many thanks

Hi,
If there has been an increase in value, then yes, as you have still sold them.
Thank you.
