Incorrect Migration Scripts (5.0)

[jpmartins]

Hello,

All database engine migration scripts to 5 need correcting similar to what I propose to mysql in #4903

Not 3 but 6 fields were drop from BATCH_JOB_EXECUTION_PARAMS according to documention (schema docs and migration guide).

Also 3 new fields were added to the said table.

Also suggest the keeping of job parameter history with add new columns, addition of 3 update queries with historic data (migrate), and only then drop old columns.

Have a nice day.

Eventually, also update the guide to contain link to the migration folder, and ... evaluate having separate sql for data migration (eventually in a syntax common to all engines if possible), maybe inspired on 2.2 migration-insert-only.sql
