Issue
When this option is not checked, it signifies that the hash file is being appended, and therefore would contain data at the time of conversion. As the S2PX conversion process migrates Hashed Files to database tables, a corresponding job to migrate that file must be run before the converted parallel job(s) can be run.
Actions
The S2PX conversion process converts Hashed Files stages to DRS stages, and for each identified file generates a corresponding Server job to migrate each Hashed File into a user-specified DRS-compatible database table. These migration jobs must be run before the converted parallel job(s) can be run.
