William Miller, managing partner at MI6, answers some questions about migrating data to the SAP General Ledger.

To learn more about the challenges organizations face when migrating data to the SAP General Ledger, I asked William Miller, managing partner at MI6, to answer some questions related to this topic.

What do you think the key areas to focus on during a migration of data to the SAP General Ledger are?

The key areas to focus on during the migration project would be data quality, data transformation, and data volumes. As you can see, the common component is data. Since migration involves the movement of existing data from the customer’s existing design architecture into a new data model, it is key to understanding the differences that may exist between old and new structures. Data transformation or enrichment can be another challenge during migration. The hidden value in migrating to the SAP General Ledger is the opportunity to take a fresh look at the current business reporting requirements and management initiatives, and design a platform that supports the future direction of the organization. Last, data volumes are key to ensuring the migration itself can be accomplished within the available cut-over timeframe.
