Best Practices for Migration to SAP S4HANA


1. Get the sizing correct for your HANA landscape

The most fundamental step is sizing the infrastructure of SAP HANA very carefully while creating a technical project plan. Oversizing could lead to excess capacity and bloated hardware while under sizing can cause unexpected delays that will increase operational costs. Hence, correct sizing the scope by decreasing the initial capital investment as well as operational cost becomes important to increase the ROI. The data results in SAP are stored in a compressed manner. Hence it is not very easy to guess the amount of memory required. SAP Quick Sizer tool along with relevant SAP notes and SAP sizing reports are used for estimating the memory requirements.  Correct sizing consists of three major steps including memory sizing for static and dynamic data, disk sizing for persistence storage and CPU sizing for transactions, queries, and calculations.

2. Choose the right migration strategy on the right platform

There are varieties of platforms and methodologies available which can be selected on the basis of business needs, resources, and budget. Businesses may choose to run SAP HANA on-premises or in the cloud.  The hardware must be enterprise-grade. Major players in this industry are HPE and IBM Power. IT platform chosen must be scalable, flexible, responsive, and secure along with the ability to mitigate risk.  Organizations can choose to use the Database Migration Option (DMO) in SAP Software Update Manager (SUM) which combines the system update and a technical migration. On the contrary, the standard system copy approach using tools like SWPM, R3load and Migration Monitor can be used.

3. Clean the data

Reduce data size will help database migration take less time. It is advised to keep only important data to perform migration efficiently. Either the data can be standardized based on the information in master data sets or the fields can be adjusted to new standard blueprints for information. Purging or archiving at regular times gives benefits like a reduced data footprint cutting the infra costs.

4. Set high implementation standards

Maintain distance from alternate routes at this phase and stick to the high and strategic standard. Being efficient in all the fundamental activities from planning to migration is the way to the successful migration. Migration team must be aware of the technical migration guidelines. SAP gives the most recent fixes and solutions for regular issues with each version; in this way, it’s smarter to use the most recent one. Remember to take regular backups and avoid unnecessary risks to guarantee smooth and successful migration.

5. Do a POC

It’s a smart thought to test your migration in a Proof of Concept (PoC) phase before you pull the trigger on the full movement. The PoC will empower you to approve the movement procedure. Performing a POC in an SAP sandpit environment will help distinguish issues that may contrarily influence the complete migration and help improve overall productivity.
