Update migration scripts to support DB2

Three of the migration scripts are causing failures with DB2.

- DB2 doesn't support nullable column in primary key

- Hard coded SQL statements which use False/True as Boolean arguments
  are not compatible with DB2. In DB2, Boolean columns are created as
  small integer with a constraint to allow only 0 & 1.

- Hardcoded update rows from other table sql is not compatible with DB2

- Foreign key constraints require additional handling
