General error: 1366 Incorrect integer value: '' for column

Hi.

Im transferring a database over so i can set it up with relationships etc on laravel and im coming across the error General error: 1366 Incorrect integer value: '' for column 'name1_verified' at row 1

I know its due to trying to save from a string to a bool but how can i make change it from string to boolean.

As it is now i have a name1_verified on both databases but it only has either 1 or 0 in on the old db. I want it to be a boolean on the new db, so in the migrations ive set it to boolean.

If i change the type in the new db to string then it just doesn't save it at all!
