SAP HANA Migration Challanges: Avoiding 3 common pitfalls with UAT from the Cloud

More and more companies are running on SAP HANA. No wonder, HANA boasts the ability to accelerate business process and analyses while, according to Forrester, providing a 70% reduction of software costs. Furthermore, SAP S/4 HANA is said to be the most efficient ERP system on the market. With the in-memory database and the connection of applications such as customer service, logistics and analysis back to the data center, data can be processed directly and evaluated quicker for more insightful, responsive business decision making.

But before you can use S/4HANA, you have to convert to the SAP HANA database.

However, the transition to SAP HANA can only be realized from version EHP 6 onward. If there are any older versions in circulation in your organization, you must first upgrade to ECC 6.0 EHP 7. And like with all change there are challenges that must be addressed during the upgrade.

The Challenges of SAP HANA Migration

1. Business plan for the SAP migration

Only when there is a business plan in place, IT managers can justify the investment for the change to SAP HANA. The challenge: With a new system it is difficult to estimate the Return on Investment (ROI) and the project scope correctly. Miscalculations in time and effort, can lead to scope creep, in turn effecting ROI estimations.

2. Missing know-how when converting to Unicode

SAP HANA only supports Unicode so a SAP Business Suite or SAP NetWeaver system must be Unicode prior to the migration. Here all known written cultures and sign systems are set as digital code. If you are using separate code languages in your old system this can become a problem because Unicode conversions are complex when your IT has developed individual interfaces and programs. That is why the adjustments for the change should be tested beforehand. Many employees are lacking the know-how to change the coding though. In the worst case they can overlook some necessary code modifications resulting in a system crash.

3. Lengthy downtimes and system failures

A typical database migration takes place as follows: First the technical preconditions need to be put into place to prepare the systems for migration. This can be run in parallel to actual operation. During the following changeover to the new database, the users cannot reach the systems in downtime. It is essential to minimize outages in order to minimize costs. With manual pre-testing, system failures often go unnoticed or they are detected too late and the go-live is delayed.
