SAP Hana is the foundation of enterprise applications developed by SAP and is used for managing data. It is mostly used by large organizations for managing business activities that include inventory control, human resource management, supply chain management and manufacturing order fulfillment. s4hana migration allow the company to easily adjust business logic so that business requirements can grow dynamically. This helps in maximizing the benefits offered by SAP Hana.
There are several reasons why companies migrate from their current database to SAP Hana database. The primary reason is to enhance data security. SAP Hana ensures maximum security of data while in comparison to an SQL Server. The other reasons are quality and performance enhancement as well as compliance requirements by the various regulatory bodies.
A proper migration of business logic should be planned in order to meet the requirements of the end users. It is necessary to identify the business process and the current data requirements before going in for a migration. The migration involves changes in database structure and application layer design as well as code modifications.
Before migrating the database, the migration tools are tested to ensure smooth database operation. Mention should be made to the migration vendor regarding the parameters to be modified in order to meet the target requirements of the database. The test cases are subjected to various tests such as concurrency, durability, performance, usability and availability. In case of any exception during the test, the tests are restarted from the start or else the entire data base might have to be reinstalled.
There are two types of migrations: master and slave. A master migration is a one-time process that starts from scratch and covers all the changes made to the database as well as all the stored procedures and indexes. The slave migrations allow changes to be applied recurrently within a certain period after the application has been installed on the server. These allow continuous updating of data without requiring roll-backs or restarts.
It is necessary to plan a migration prior to its execution. It is best to discuss with the migration service provider about the expected outcome and to prepare the testing environment. It is important to consider all the options available before taking a final decision. Choosing a right migration solution will ensure smooth running of the business.
The primary aim of any MRO application is to convert the data of an enterprise database into a format compatible with the application servers. HANA is no exception and therefore it is important to convert the data from HANA into a safe and compatible XML format. This can be achieved using the Data Mart tool that is readily available with the SAP HANA Cloud and Enterprise editions. The tool uses JAR format for data conversion.
