STEPS INVOLVED IN MIGRATION
What is SAP HANA Migration? • SAP HANA migration refers to the process of switching from any database offered by SAP to SAP HANA • Once the migration process is complete, SAP HANA becomes the main database that is going to support the SAP landscape for any business • SAP HANA is a columnar database, unlike the traditional RDBMSs, which are row-based.
Step 1: Sizing the SAP HANA Landscape • It is an important step considering the need to create a technical plan • It helps the businesses in understanding the maximum benefit that they're going to receive based on their investment • Undermining the SAP HANA landscape results in unwanted delays and thus, increasing the cost of operational performance.
Step 2: Choosing the Right Platform • Migration to SAP HANA can be done quickly when the businesses have determined the right platform to cope up with their needs, budget and resources • If SAP HANA is deployed on-premise, it provides maximum control with reduced risk • If SAP HANA is deployed on cloud, it offers flexibility and scalability
Step 3: Cleansing Data • Data cleansing is an important step that has to be performed before the integration of SAP systems takes place into HANA • The benefits of cleansing data include- • reduced data foot print helps in minimizing costs related to infrastructure, hardware and licensing of SAP HANA • reduced data size allows businesses to perform technical migration with low business downtimes • with only relevant data present, SAP HANA performs better after technical migration has taken place
Step 4: Applying High Implementation Standards • Businesses' technical team needs to deploy high standards when the migration process takes place • The team needs to have a comprehensive understanding of guidelines related to migration • Businesses also must avoid unwanted risks that might occur during the migration of a database as it may result in hindering the smooth migration
Step 5: Performing Proof of Concept • The businesses also must perform a "Proof of Concept" in an isolated environment. This helps in validating the migration process on an SAP HANA platform
