SAP Data Management: Your Guide to SAP HANA Migration

Tuesday, June 6th, 2017


The SAP HANA has the potential to offer your business significant cost and efficiency savings through faster access to real-time data and analytics, enhanced functionality, and the simplification of your IT environment. The migration process might seem like the tip of the iceberg when it comes to extracting full value from the appliance, but has a large impact on SAP HANA’s total cost of ownership (TCO). SAP data management forms the foundation of an efficient SAP HANA migration by reducing the costs and downtime involved in the process, as well as long term TCO.


SAP data management reduces the cost and downtime involved in migration, but only if implemented pre-migration

The costs and downtime involved in a migration to SAP HANA depends on how much SAP data you need to carry over to the new appliance. Carry too much data over and you not only increase migration times, but HANA size requirements too—the cost of which increases with every gigabyte for both the hardware. More data within the SAP HANA appliance also means slower response times and appliance refresh expectancies. Although the migration process itself has been streamlined thanks to the different migration path options offered by SAP, your SAP data management strategy needs to be outlined and implemented well before migration can happen.


The first step in a SAP HANA data management strategy is to conduct an assessment of SAP data

RightSizing underpins a SAP data management strategy. Before migration can happen, you need to take stock of your entire SAP database. This process will help identify what data can be deleted (if outside its retention period), what can be archived using SAP information lifecycle management (ILM), and what needs to be carried over to SAP HANA.


Determining HANA size requirements is a pivotal step in the migration process

Once you know exactly how much data is necessary to migrate to SAP HANA, you can determine its size requirements. Without a SAP data management strategy, you could either over spend (and increase migration times) if you opted for a HANA appliance that was too large, or select a HANA appliance that was too small for your IT requirements. Selecting the right size HANA appliance means you extract the highest long term value from the system while minimising migration time and costs.


SAP data management goes beyond the migration process

After RightSizing SAP data, you’re ready to migrate to HANA using the migration path option most applicable to your needs, for example using the database migration option (DMO). Data management performed before migration facilitates ongoing SAP HANA management by controlling data growth once you begin using the appliance. Flatlining data growth ensures the fastest appliance response times, but only if continued on a regular basis.
