Preparation of the migration to the SAP HANA database
Implement notes
Every SAP system architecture is as individual as the company itself. Full planning, including hardware sizing, is therefore essential. These services are included here:
There are several ways to introduce and operate new applications. As a company you have the choice between internal realisation and operation, outsourcing, cloud computing and so-called outtasking. In deciding on one of the above concepts, the SAP basis must be included for the evaluation of various technological and operational aspects, which offers the possibility to develop a sound decision. This decision has a significant impact on the future operation of SAP and the associated operating and maintenance costs. The recommendations listed here are intended to help you decide on other forms of service. Information on the recommendation can be found in the Master's thesis in chapters 7.8 and 9.6.
(De-)installation and update/upgrade of SAP AddOns
SAP HANA has been one of the major topics in the SAP environment for the last few years. Many customers are currently faced with the question of whether or not to migrate your SAP system. In addition to the actual changeover itself, there are many other topics on which you should have already informed yourself in advance, as these influence the success of SAP HANA in your company. What do you already know about SAP HANA? I would like to encourage you to think about security in the following article. If you would like to learn about the architecture of HANA, I recommend a contribution from our colleagues at erlebe Software. SAP HANA Scenario But why are we even talking about HANA Security? Why is it so important to consider new security strategies with the new technology? With HANA it is possible to analyse data quickly. BW scenarios primarily benefit from the in-memory database (IMDB) used, as speed advantages in data access are particularly positive. Compared to a classic ERP / R3 scenario, the normal DB is replaced by HANA. The desired speed advantages result. However, migration is expected to be required for the changeover. This is caused by customer-specific developments in the system. HANA is not a further development of SAP ERP, HANA is the next stage of an ERP system. It is well known that an ERP system contains the capital of the companies. Therefore a new HANA system like all other ERP systems is also interesting for attackers. On the one hand, such a system contains the critical business data that are available for espionage. In addition, most business processes are mapped in such a system and offer an attack surface for sabotage. In addition, users do not initially know the new technology well. This also applies to administrators in the area of a new technology. Attackers quickly gain a dangerous leap of knowledge over these user groups. SAP HANA has a lot of new features, although many existing ones are used by SAP ERP, so there is a risk here.
Some missing SAP basic functions in the standard are supplied by the PC application "Shortcut for SAP Systems".
