1) there is no issue when you are converting NOT NULL column to NULLABLE column even if get null data from source.
2) But when you are converting nullable column to NOT nullable column also you will not get any issue if you get the NOT NULL data from source,
if you get nullable data from source then job will ABORT.

When
col is converted from not null to null and data coming has
null or not null values then NO Problem.
But col is NULL constraint and converted to Not NULL then
two cases
i) when data coming from source has no NULL values then no
problem.
ii)when data coming from source has NULL values then the job
simply ABORTS.
