The fact that all new SAP business solutions are now based on SAP HANA database, the migration to SAP HANA for an enterprise is a natural transformation. Add to it the fact that they can opt for on-premise or over the cloud deployment, making SAP HANA suitable for all businesses including startups with low budgets.

The migration to SAP HANA becomes even more essential if the enterprise is already making use of any of the SAP solutions and services on offer. SAP with its HANA database has made a conscious effort to base all future application on the SAP HANA. Migrating from using a random database or a mixture of various database solutions to a uniform database like SAP HANA allows businesses to leverage the power of all associated SAP business suite solutions.

An overview of SAP HANA migration routes
To leverage the power of in-memory database like SAP HANA, the business enterprise must follow a streamlined migration strategy. Since the final goal to adopt SAP HANA is to ensure faster business processes with high use of smart analytics with a simplified IT environment. As a business enterprise, here are the various routes you can take to ensure a successful migration to SAP HANA database.

SAP HANA is an in-memory database and to make a successful migration sizing up the HANA landscape is essential for a business enterprise. With the correct sizing the total cost of ownership can remain under check offering the optimum benefits of SAP HANA migration keeping the costs low.

SAP HANA database makes use of the main memory as per the actual data which is to be stored in real-time. The catch is that the actual data in HANA is compressed and hence difficult for businesses to guess the exact size of their SAP HANA landscape. Thankfully, there are various sizing tools that can be used to decipher such a situation and understand the sizing requirements. The use of solutions like SAP Quick Sizer or SAP sizing report can help businesses choose the right memory size, disk size and CPU size for associated data in the SAP HANA landscape.

An on-premise deployment on the other hand allows enterprises to make use of a pre-configured hardware from SAP partners allowing them in time saving to ensure SAP HANA as an in-memory database gets configured behind the enterprises’ firewall for added protection.

For those enterprises opting to go the cloud way for a SAP HANA migration strategy there are again options of choosing between SAP HANA Enterprise cloud which is SAP's very own cloud offering or opt for any third party public cloud providers using an independent SAP HANA licensing.

SAP HANA with all its benefits and advantages of use as an in-memory database can be quite an expensive migration for many enterprises. One of the best ways to ensure a successful migration that checks the cost effectiveness box as well involves choosing the right licensing metric. As a SAP HANA user, an enterprise has the option to either opt for a run time charge based on the database usage or seek a payment structure that is linked with the total volume of data that gets managed by the SAP HANA database.

SAP has a transparent pricing structure as it makes use of the HANA Software Application Value (HSAV) to reach the final amount of data being used by SAP HANA database. A fixed percentage as a fee is charged by SAP for the data managed by HANA database.

Before choosing the suitable payment, licensing strategy also insists of getting a proof of concept to understand the changes involved with the migration. Usually in a proof of concept a SAP Sandpit environment is created helping the business understand the power and functionality that SAP HANA database offering will have on the day to day functioning of its various business systems.
