EMIGALL: Data migration, step by step explanation

SAP IS-U migration workbench (Tcode-EMIGALL) is an SAP IS-U tool to migrate legacy data into the SAP IS-U system. SAP has provided migration objects like PARTNER, ACCOUNT, CONNOBJ, PREMISE.. etc for migrating the corresponding data. If SAP provided migration objects are not satisfying our migration requirement, we can create our own custom migration objects.

We take connection object as a reference to explain EMIGALL data migration process. Following are the steps to migrate connection object data into SAP IS-U.


1. Create our own company in EMIGALL by copying standard company 'SAP'.

We have to create our own company in EMIGALL for migrating data because we are not supposed to make any changes to the standard company SAP. If we make any changes to this SAP company, we will not have any standard company where we can compare.

2. Copy migration objects to our own company. 

Identify the migration objects based on the data that needs to be migrated from legacy to SAP. In our scenario, we are going to migrate connection object data. So the migration object for migrating connection object is CONNOBJ.

3. Create an actual Connection Object in SAP IS-U using Tcode ES55. 

This help us to identify the fields that needs to be configured in the migration object.

4. Configure the fields of migration object.

When we copy a migration object of the standard company SAP, all the available fields are copied. But we don't need all these fields. So we need to identify the required fields based on the business requirement and those fields needs to be configured.

5. Create EMIGALL sample file format and download it.

The format of EMIGALL upload file varies based on the migration object and its configurations. We can download the file format by providing sample data.

6. Create a conversion program to convert legacy data from excel format to EMIGALL supported format.

A conversion program needs to be created to convert legacy excel data into EMIGALL supported txt file format.

7. Upload the converted legacy data using EMIGALL in batch job.

After converting the legacy data into EMIGALL supported format, we can start uploading legacy data.
