ISA schoolboy error help

I have made a schoolboy error by withdrawing all money from an existing ISA account to my personal bank account & then opening a new ISA. My original ISA is a flexible cash type opened in the previous tax year but has rolled over into the current tax year. I have made contributions to this ISA in the current tax year with my balance close to the maximum allowed in this tax year for the purposes of opening a new ISA. Two questions, I am assuming the contributions made this tax year in my original ISA, together with the balance deposited from it to my new ISA would exceed the threshold? Also, could I simply withdraw all the money from my new ISA back to my original and then use the transfer service to move it back again without affecting my allowance? Thank you.
