SAP HANA has been SAP’s most powerful technology development in the past few years and almost all SAP products published after SAP HANA have extensive integration capability in this network. SAP HANA is not only a modern database .it is a premise or cloud-based in-memory data platform that enables you to speed up business operations .Provide more predictive analytics with specialised technologies and abilities to manage your organisation more quickly and simplify your IT workplace.
This blog is created to help develop and implement a successful technical SAP migration to the SAP HANA platform and aims to choose a high-level summary, we providing most important neglected steps, with a aim to reduce the risk from organization to SAP HANA
STEP 1: CORRECTLY CLEAR PICTURE OF YOUR HANA LANDSCAPE
While developing your technical project plan, this is the most important and primary landscape. You can acknowledge the maximum profit of your investment with the help of this plan, which can also reduce the long-term maintenance costs. If the sizing is inadequate and over-supplied, it can result in extra volume and over-supplied hardware. While if the sizing is under-supplied, it can guide to unexpected delays, which will also raise the cost of present performance. It’s hard to find out how much memory is needed because the data is usually restrict in HANA and its outcome depends on the scenario used. Using the SAP quick size tool, relevant SAP notes and SAP sizing reports, memory sizing for SAP HANA can be done.
SAP HANA memory can be sized correctly by following the below steps:-
- Memory sizing for static and dynamic data.
- Disk Sizing for storage of persistence.
- CPU sizing need for transactions, queries, and computations.
Step 2:-CREATE SUITABLE PLATFORM AND MIGRATION STRATEGY:-
By selecting the correct platform that best suits your business requirements, budget, and resources, you can migrate quickly and smoothly to SAP HANA. For maximum control and decreased risk, SAP HANA migration can be dispatched on premise or in the cloud for greater flexibility, usability and faster value time. In the cloud, it is arranged for increased adjustability and scalability and faster value time. When installed on premise, organisations can choose any of SAP’s hardware partners for certified sap hana applications. the assistance of the pre-configured assignment with pre installed software from the hardware supplier, the companies will connect with the time period power of SAP HANA in-memory stage. the companies will get the confirmed answer by SAP still as hardware vendors by utilising this preconfigured technique.
There are multiple cloud installation scenarios are available. SAP has its own particular private cloud offering called the Enterprise Cloud of SAP HANA. It includes a certificate for SAP HANA software. If you have a lot of technical problems with your current system and want to continue with a greenfield strategy with specific data SAP migration for SAP HANA, then a fresh installation on SAP HANA might be better. After completion of sap HANA scenario, then you have to choose maximum effective migration strategy to decrease unexpected problems and remove harder system downtime throughout technical migration, you need to choose the most active migration strategy so that you can achieve faster value time.
To reduce unexpected problems and remove harder system downtime throughout technical migration, you need to choose the most active migration strategy so that you can achieve faster value time.
In standard migration is the premier and particularly used as a Operational system or Data Base migration strategy that is generally a heterogeneous system copy using conventional migration tools like SWPM, R3load and Migration Monitor. If you don’t want any latest version to run sap hana for your system and you have to execute actual migration for detail If you need to achieve the regular migration without any latest update for the process to run on SAP HANA, the standard SAP migration strategy may be the best method. For instance, if you want to migrate your Company Suite or BW system to SAP HANA as it does without any existing element.
If you facing several technical problems with your current system and would like to continue with a greenfield strategy with specific data migration for SAP HANA, then a fresh installer on SAP HANA might be better. This solution can also be an effective method for businesses with predominantly standard SAP methods and planning to choose S/4HANA cloud with similar smaller data footprinting. SuccessFactors By SAP.
STEP 3:-CLEANS YOUR DATA
Sap hana providing good deals like latest analysis and opportunity to maintain your company activity by analysis huge data in real time period. It runs better than any classical database we already know, but you know what’s better?
Even Reduction cost it run faster! Data maintenance is one of the vital tasks you need to do before you take your SAP systems to HANA, but it is also the many overlooked step, unsurprisingly. Cleaning up your data gives you three major benefits:
- When reduction of data size it will allow to perform technical migration with reduction of business downtime
- your infrastructure, hardware and SAP HANA licensing costs decrease when data footprint decrease
- Later the technical migration SAP HANA performs even improved ,By preservation apart quality and vital data in your system
The above figure gives instructions for a correct process of data cleaning. Note that the operations specified here may improve, depending on the needs of your company and business processes. You must make sure that you apply the most appropriate method of data cleaning to your own business. Deleting technical data, app logs and system logs is usually okay. To decrease the range of your database, you can always collect your older business data.
STEP4:-ADDITION STEPS APPLY HIGH IMPLEMENTATION STANDARDS
In the project implementation phase is the most critical phase.in this implementation process is the project’s most critical phase. Throughout the project’s technical migration, it is not suggested to create shortcuts and it is necessary to allocate the time to execute it properly. Rather than taking the shortcuts during the project implementation phase, it is sometimes required to concentrate on keeping higher standards in operations. The necessary activities should be systematically planned and understood. To effectively bring out technical migration, the tech team must have sufficient knowledge and understanding of technical migration guidelines, important SAP documents, and best methodologies.
When things went wrong during technical migration takes place, you should prepared be better equipped and less likely to make errors. confirm your source systems are prepared for their journey to SAP HANA. It’s safer to be on the latest version even if your source system version is supported for migration. With each release and support package, SAP provides the newest fixes and solutions to common problems. Once launching a migration project, make sure that your system has these in place.
Particularly while migrating your database, do not take any risks. You will never have enough backups, so ensure you have complete backups and archive logs to restore points on a regular basis. To ensure smooth technical migration, remove frequent risks.
Don’t take shortcuts and always maintain high standards if you want your project to be a great achievement
STEP 5:- TAKE A CONCEPT PROOF
You need to perform a “Proof of Concept” during a cavity setting first, thus you’ll “validate” your migration method to SAP HANA platform. you’ll try this by repeating your SAP Production system to form SAP cavity setting and perform the particular migration on this technique first.
This is a critical step for any process for technical migration and I can ensure you that it is worth it because the expense of duplicating the environment:-
- Discuss potential issues to decrease project risk in the sandpit system.
- In a non-critical environment, you will have more testing and verification time
- It provides the project a sense of momentum throughout project
- It helps you make critical decisions in your project plan and improve the overall efficiency of the project
