Tadpole question

Good afternoon all and thank you for letting me join this group.

We have recently closed our large Koi pond because of a leak but now have discovered in the bottom where rain water has collected we have tadpoles. We have created a new wildlife pond as the old pond is due to be broken up and filled in.

Can we move the tadpoles to the new wildlife pond, I don’t know if the frogs will stay there but they won’t be able to get out of the main pond as it’ has 6’ deep walls
