Yes you can! π And actually, Dodl is one of the only lifetime ISA providers this is possible with (yay!). To transfer yours, simply open a Dodl lifetime ISA then enter the details of the one you're bringing over to it.
While your transfer is in progress, you won't be able to add cash or invest within your new Dodl lifetime ISA. But once it's completed, the team will let you know and you'll be able to log in and start managing your lifetime ISA's cash and investments.
