Translate the Hashed File stage to its Parallel equivalent (a DRS stage), and
Generate a new, entirely separate utility Server job which is intended for the one-off loading of Hashed File data into a DRS-compatible database table.
...
See Hashed File Database Tables to understand how the database tables will be named and the structure of the data in the tables.

Only hash files that had at least one input link will be migratedHashed Files that posses one or more input link (i.e. incoming data to be written) will cause the generation of a migration job. |
Each migration job will be wrapped in a Sequence that will include a single Activity Stage. The reason for this Sequence is to receive the parameters that the original job would have received and then supply the necessary parameters to the migration job. For example, the Sequence will generate and provide a couple of parameters to the migration job, which the job will use to set the database table name.
...
Each Hashed file stage (with at least one input link) in the original job will ;had to cause the generation of a Hashed File stage (of the same name) in the migration job. The number of input links that the original Hashed File stage has will be the number of output links the Hashed file stage has in the migration job.
...
The wrapper Sequence will simply include one Activity Stage that will call the migration job. Example:
...
Usage
To migrate the Hashed Files , each Sequence provided should be called in the same manner as the original job. ThereforeIf, for example, if the original job was always called invoked once, with a fixed single set of parameter values (or none at all), then the migration Sequence should be called once with the same set of parameter values. If, on the other hand, the original Server job had was invoked multiple executionstimes, with differing sets of parameter values for each invocation, then the equivalent Sequence should be called invoked once with for each set of parameter values. This will ensure that all Hashed Files are migrated appropriately.
