History and Multiple Process

The History and Multiple Process utility is used for actual data migration for a customer. The objectives of this utility are as follows:

- In case some source data tables have huge amount of history/dead data (data that is not going to change), you can migrate the data in advance so that during migration, the system down time is less.
- In case some live source data tables have huge amount of data, you can think of migrating the tables, using multiple processes.

Fields | Description
Conversion Objects | The list displays the conversion objects, i.e., target tables for which history/multiple processes setup is completed. Click the arrow to view the details of source tables and fields based on which the data can be grouped into various data sets
Conversion Object | Displays the details of the selected conversion object
Main Query On | Displays the source table name from which data is migrating to the target table. The number of source tables corresponds to the number of migrate tag in your conversion object.
Source Fields List | You must enter the source table fields to group the data in the table. To specify more than one field, separate the fields using a comma. You must enter the field name, without the table name preceding it. In case of Infor tables, if you are splitting data based on primary key, you can just enter ‘index1’.
