Now that you have checked the advantages of SAP HANA, you might be more confident to execute the migration. Nonetheless, before choosing to MAKE the transition, you also have to be mindful of the shortcomings you’ll encounter during the process. Here are some of the disadvantages you should be cautious about while shifting to SAP HANA:

• Planning: PAIN Points: Many companies fail to recognize the actual problems of their existing database infrastructure. Therefore, they miss the scope of the project. This results in wasted endeavours and resources. Without a concrete project goal and precise estimation of project expense, you will not have an accurate roadmap to digital transformation, thus it can negatively affect your Return on Investment (ROI).
• TECHNICAL Issue: Code Conversion: Other shortcomings emerge from the technical ASPECT of the migration. If your system is still operating with a non-Unicode LANGUAGE, then it can cause a major challenge to migrate to SAP HANA. SAP HANA only backs the Unicode system, so most of the new SAP NetWeaver technology and SAP applications will be available only in Unicode. Thus, the requirement for Unicode system conversion has to be executed mindfully before moving to SAP HANA. Many companies are not aware of this knowledge of conversion, as a result, leads to system failures and waste.
• Execution: Downtime: Like in any other migration project, it all begins with an initial migration in the sandbox for the purpose of testing. Post which, the migration moves to Development and Quality before eventually advancing into Production. The primary problem when shifting to Production is the downtime as the consumers cannot access the system during this process. There might be a greater possibility of system failures during the migration if you do not pre-test the new database system comprehensively. It would lead to more significant downtime or worse, failures would be detected too late, leading to even lengthier outages.
