Digital transformation cannot be achieved in any organization unless there is a proper strategy to migrate data from source to the new environment. Choosing the path for data migration is a basic requirement for implementation of digital transformation by leveraging SAP HANA as well as SAP S/4 HANA.
There are two types of scenarios for data migration if you are following SAP for achievement of digital transformation across an enterprise. These are based on the data volumes that need to be migrated. While moving data from the environment of source to that of HANA one needs to understand importance of proper timing in order to avoid complications.
Data migration can be a significantly costly and lengthy affair unless you follow the best practices offered by SAP for data management. While the best practices will assist for handling complexities and cost related matters, you will still have the freedom to adopt different types of strategies in accordance with the systems.
Large volume data transition
Large and very large volumes of data need a distinct approach for transitioning towards SAP HANA Cloud environment. These data volumes can be in excess of 10 TB and one must proceed with care because the entire effort might turn out to be time consuming, cost intensive and complex. However, if you choose the proper tools and begin the planning much in advance, then you will not only be able to save considerable costs but can also meet the timeline of going live.
Reduction of data in terms of the size must be approached by shrinking the volume of system. This would not be easy unless you have archived the data to facilitate any changes in the system. Such approach will enable you to deal with complex issues of cost concerns, and size related problems.
KTern is the most sought after accelerator that automates as well as hastens the entire process of archiving data volumes. The accelerator allows your IT teams to concentrate on functions that are in line with core competencies. In fact, KTern can support parallel archiving of several jobs.
Small sized SAP system approach
If you thought that the data transition approach is only applicable in large SAP systems, then you are mistaken. Every company needs to evolve a data management strategy for transitioning to HANA environment including those with less than 10 TB data volumes.
In reality, smaller companies have an edge over their larger counterparts because it is possible to pursue a phased data migration strategy to further mitigate volumes of data that are being moved. This approach is also found to enhance performance of the system while reducing IT costs.
Phased approach of moving data volumes that are smaller than 10TB allows enterprises to buy time while preparing for their ultimate objective of migrating to SAP environment in terms of S/4 HANA or SAP HANA. Companies are in a better position to maximize data volumes that are being archived while ensuring greater support of users.
Transitioning to an entirely new HANA ecosystem by adopting a Greenfield approach involves challenges of different kinds. There is a need involve legacy systems by choosing a data transition approach to look after management of leftover data.
It is obvious that irrespective of the approach of data migration, one can achieve significant gains only by minimizing the volumes of data that need to be migrated to new SAP HANA and SAP S/4 HANA environments. These advantages include improved performance of SAP systems at much lower costs with reduction in complexity of the whole transition process and possible risk factors.
Understanding the urgency
The countdown has already begun for companies that are operating SAP ERP systems since by 2025 SAP will cease to support these systems. Considering the total number of years before the dawn of 2025, one may feel that there is still a long way to go before begin preparations for S/4 HANA migration.
If one tries to appreciate the magnitude of the task at hand for companies that are contemplating transition to S/4 HANA, it is easy to fathom the enormity and complexity of such task. Obviously, there is an urgent need to begin planning for infrastructural changes ASAP, unless you wish to be left behind.
Irrespective of different levels of complexities that exist in SAP infrastructures of various organizations, an appropriate strategy for transition is need of the hour. This applies to all SAP enterprises that may be operating in hybrid cloud, cloud or on-premise environments.
Takeaway
Following the announcement of SAP S/4 HANA, several organizations began pondering about the exact time to adopt the new SAP landscape. If your organization is still toying with the idea, then there can’t be a better time to start preparing for the transition than now. With every passing day, there is a better clarity about unique advantages of S/4 HANA and therefore SAP enterprises should start chalking out strategies for a transition without losing any time.
