Data Migration - SAP

Logical Analysis specialises in migrating data from non-SAP to SAP environments for enterprise logistics, financials and human resources systems. The process involves use of the SAP Data Services for rapid migration and the following methodology:

• Identify and engage data owners to review legacy data to determine the extent of irregularities.
• Develop the mapping and conversion rules for the migration.
• Write the extract and load programs based on the rules.
• Create post-testing decision tree for potential data and rules adjustments.
• Conduct unitary testing on small sample data sets.
• Determine the data validation routine.
• Load test full size data set and engage the appropriate resources for data validation.
• Obtain indicative timing and sequencing for input to the cutover plan.
• Load the full data set into the Test System in trial cutover and UAT set up.
• Load the full data set into the Pre-Production System and obtain sign-off.
• Perform the full migration with cutover to Production and obtain final sign-off.

The complexity is in the irregularities. Logical Analysis will lead the client to understand the resources and time required for a successful data migration exercise.
