== Migration Script ==
All the functions that does the migration have been added to migration_scripts file . migration_scripts file internally calls the functions of migration_helping_methods file too perform the migration . Thus in order to do the migration one just needs to import migration_scripts and call the method corresponding to the migration he wants . Also the user who wishes to do the migration in the db doesn't have to know the internal functioning of migration_script , thus the functions or the methods declared in migration_helping_methods file doesn't concern him.
