Investment acc to ISA acc

Hope everyone is well and safe! Please can anyone help or give tips if you can transfer stocks from t212 investment account to the t212 ISA account guys? Like will it be in the future according to some of their stuff I spoke to their working with. If not what’s the best way to do this/tips etc thanks guys!

HMRC does not allow transfer of stocks into an ISA. You have to sell in the Invest account and then rebuy in the ISA.
