Changing column type from Decimal (16,2) to Decimal (32,2) on table size 500million rows

Hi folks I have a database part of an AG,I need to change the column type from Decimal (16,2) to Decimal (32,2). Does anyone know the best way I could do that above without bloating the log? My thinking is: 1 - take the database out the AG 2 - create a new table with the requested datatype (32,2) 3 - insert the data into the new table Any suggestion ?
