Answer 1

Not really an answer, but just a note about ->change():

Only the following column types can be "changed": bigInteger, binary, boolean, date, dateTime, dateTimeTz, decimal, integer, json, longText, mediumText, smallInteger, string, text, time, unsignedBigInteger, unsignedInteger and unsignedSmallInteger.

If your column isn't one of these you will need to either drop the column or use the alter statement as mentioned in other answers.
