Technical conversions include moving the database update system from SAP HANA to the current one, as well as a combined release upgrade from SAP ERP and SAP S/4HANA cloud.
This is a complex process that goes on for days. The importance of planning cannot be overstated. To begin with, you must comprehend the state of the ecosystem and how it functions. Additionally, find out how long each process takes, especially if it is time-sensitive.
A report states that the main factors driving the growth of data migration are rising business requirements, data volumes, and the adoption of big data technologies across different industries.
Every organization today relies on large amounts of data for its day-to-day operations. Depending on the data being moved from one database to another, there may be times when you need to convert or move it.
As long as SAP systems are still in use, the issue of data migration will remain a significant concern in practically all SAP adoption projects. Starting with the quotation phase and continuing with the awarding of the order, the overall image is murky. However, the client and service provider must evaluate the expenditures.
Although "database conversion" and "database migration" are frequently used interchangeably, they are two different processes with a significant impact on how software is implemented in an organization.
Conversion: What Is It?
The process of extracting data from a dormant database and changing it to a more appropriate format is known as data conversion. It is then transmitted to a new instance. The target database determines the design of the data after conversion. You must convert video and music files to be compatible with your smartphone. To use an MKV file on your mobile device, it must be converted into an MP4 file.
Data conversion is frequently a step in data migration. If the fields in your old system and the new system were the same, you could do a data conversion. This isn't always the case, though. Before transferring the data from your old system to the new one, you must make adjustments.
Translating data to fit target systems (data should be prepared according to target systems) and then moving the summarized data through interface programmes is known as a conversion of data. Because both the source and target formats must be thoroughly understood, transformation can be challenging. You face the danger of having your data compromised during conversion and having its integrity ruined.
All data integrity should be maintained during database conversion. When transferring data from one database to another, modifications might not be necessary. It could be required to do a database conversion to correctly preserve, analyze, and read the data in the target database if the target instance's formatting differs from that of the source database.
Conversion Process
Data Loading and Review: Check and verify the accuracy of the data being loaded into a new system or database. After the information is validated, it can be loaded into production.
Despite the fact that each database conversion project is unique, all conversions must adhere to a set of standard stages.
- Analyze both the source and target databases.
- Create a plan that is based on the requirements of the project and the needs of the end user experience.
- You should test the conversion at least three times and then quality-check the results.
- By converting or changing the data to the format required by the destination database, you can carry out the strategy.
- Final results are quality relevant services checked.
It is advised that you steer clear of data conversion issues.
- Convert objects to character data formats that can be printed, including numeric data.
- For an object that has been converted to a binary type of data, create an operating system-neutral structure.
- Include enough header information in your changed data type for the remainder of the encoded item to be interpreted appropriately.
Conversion Issues
The complexity of database conversions is due primarily to the source and new formats' differences. To prevent data loss of integrity or corruption, it is crucial to have this expertise. Additionally, duplicate data may need to be consolidated, outdated data may be removed before translation, and inaccurate data may need to be manually corrected.
Planning an SAP 4HANA System Conversion
This is a complex process that goes on for days. The importance of planning cannot be overstated. Before making the conversion, you must comprehend the atmosphere it will operate. Additionally, find out how long it takes to complete each phase, especially if it's a time-sensitive phase.
Conversion of a Sandbox System
It costs money to set up a sandbox like that. You'll need a server if you want to run SAP ERP. For SAP HANA, a database server can be necessary. You can use the SAP HANA appliance, if it has already been delivered, to test the conversion before erasing the database. You will need time and employees to construct the system. All of this is accurate, yet the investment is still necessary. The benefit will be a timely and cost-effective conversion that fits your budget.
The sandbox environment must meet two conditions
- The database should be the same size as the production system. The amount of data does not always affect the conversion time. However, it significantly affects how long critical phases take to complete. Utilizing a copy of the production software is the most effective way to establish the sandbox. It is best to make a copy of the development program because these systems frequently have tiny databases.
- The hardware of the sandbox server should be capable of processing the same volume of data as the production computers. The timing data gathered during the test migration could be utilized as a worst-case estimate if it turns out to be slower. However, it shouldn't take much longer. Although it may seem silly, it is conceivable for the sandbox to operate on hardware faster than the production system. If the production servers are old, there is a potential that the sandbox will convert more quickly than production.

Conversion of the Development System
The knowledge management strategy you learned from tests or other conversions should give you the confidence to take on core systems. The development system comes with one warning. Compared to QA and production systems, these systems are frequently "dirtier." They include unfinished development work that is still in progress and hasn't been tested, as well as occasionally outdated, out-of-date code, test objects, and other items that developers may have started working on but never finished. There are a lot more objects in these systems than there are in production and quality assurance, which could lead to issues during conversion.
Conversion of the QA System
The databases used by QA systems are typically clones of production databases that are similar to production in size and content (most QA systems are more current copies of production) (representative data from the business one and a cleaner repository than that of a development system). An early run-through of the exhibition is the QA conversion.
Conversion of the Production System
In a perfect world, changing the manufacturing system should be simple. You are aware of the timing of events. From beginning to conclusion, the entire procedure is documented. Even in a world with imperfections, this is how things can occasionally function. We have experienced upgrades and conversions where we could essentially switch off our brains and follow the instructions without question. The entire process ran smoothly.
S4 HANA Conversion Strategy
Step-by-step instructions are provided to help you choose the right S4 HANA conversion strategy.
Preparation
You should make sure you have the right people at the correct times to perform tasks such as configuring the software and verifying that your database and operating systems are up-to-date.
Think About Who Your Dependencies Are
When you have many SAP systems, interfaces, and landscapes coming together for your S/4HANA migration, you need to consider who your dependencies may be.
Runbook Approach
We'll create a copy from your ERP to back up during the move. We tweak the usual runbook to establish how much data is accessible and what problems need to be fixed. The SAP environment is migrated using our runbook. We swiftly carry out the migration based on the data in the runbook.
Dealing with Data Inconsistencies
This process is imperfect and can lead to data inconsistencies, especially in financials. The runbook approach reviews the data several times until we are happy with the results.
Attention to Custom Code
It is possible to move standard codes from one program to another. However, custom codes are more complicated. We will review your custom code as part of the technical assessment and provide you with recommendations and pricing for any revisions.
Technical and Functional Focus
You can now run S4 HANA after completing the technical stages. After the technical procedures are finished, there are some other actions to be taken. If you want to be sure that S4 HANA is being used by your company, you shouldn't skip these steps. The system can be deployed to clients for testing once the technical experts have finished their work and the functional consultants have started the configuration stages.
What is Migration?
Data translation into another format is referred to as database conversion.. Still, database migration is the act of moving data from one source or arrangement to another.Data migration necessitates quality assurance procedures from the destination source, including data cleansing, profiling, validation, and validation.
Data migration is moving data from one system into another with interface Programs/APIs, provided that both systems have the same data structure.
The process of transferring your data from one system to another is referred to as data migration. When you develop a new ERP system or human resource information system to decommission the current one, this occurs. Data migration is a transient phenomenon. The legacy system will be removed once the migration is finished. It may take several test migrations to guarantee the correct mapping. Before going live, the final migration is only performed once.
Most business bydesign need to migrate their databases when they upgrade their systems or use cloud services. Storage, cloud, and application migration are the three basic types of database migration. Storage migration transfers data from outdated databases to more recent versions that enable access to more recent systems. Moving data from one cloud instance or data center to another cloud foundry is referred to as cloud migration. The act of migrating involves shifting existing data to a new version or moving a whole application to a different location.
Migration Process
Reviewing your current database, mapping data to find discrepancies, and finally moving data to the new database are all steps in the data migration process. Testing is then carried out to ensure that all data has been effectively transferred.
- A general review of the database and current implementation
- Data mapping, or a thorough review of tables and data to identify discrepancies.
- Recognizing which tables contain the data
- Recognizing the areas where data must be moved to
- Transferring the migrated data to the new database
- Test the data and use it effectively
To avoid any migration problems
- Before migrating data, ensure that all data fields from your old database are present in the new one.
- Learn how the programs deal with different file formats
- Check whether any data fields are going to be merged during the process

Migration Issues
Database migration is complicated, although it could seem straightforward at first. The new system must have fields that can match data from the past. If not, the data can disappear throughout the migration procedure. Before any migration occurs as part of a database conversion, a process to verify that data sets are accurately mapped is often carried out. Before completing a database conversion, it is crucial to adequately plan to lower the possibility of issues.
Why do we need to do this SAP HANA S4 Data Migration?
S/4HANA now uses an in-memory database. The previous databases were outsourced. We need to transfer all data from the old database to the new S/4HANA S/4HANA cloud because there is a lot of it.
We perform the SAP HANA data migration to ensure that all data is transferred to the new platform. We can not only reduce the limitations of the old databases but also get all data connected and in sync.
Planning an SAP 4HANA SystemMigration
Workstreams are tasks that SAP Activate approves. The system data migration workstream is for on-premise data migration. The data management workstream is for cloud data migration.
Here is a list of the tasks that SAP Activate recommends for each phase in an SAP S/4HANA implementation.
New Installation
This is where we install HANA. You can either do it without making any changes to existing solutions. You can also select data from a current solution and migrate it to HANA.
Classic Migration
This is where we upgrade the system and make it available for SAP HANA support. We then migrate the database to HANA.
Using DMO
DMO, or the Database Migration Option, is used in this option. This upgrade and migration are combined. As a result, we can migrate in a single step rather than numerous. Consequently, it is a one-step technique that only uses one tool.
S4 HANA Migration Strategy
SAP claims that SAP S/4HANA will provide customer relationship management with more excellent value and efficiency. No matter the reason, the effects are honest and will last a lifetime.
Over 75% of worldwide transaction income touches an SAP system, and there are hundreds of thousands of SAP clients worldwide. So, SAP can become a crucial and essential component of your company. If your business wants to keep using SAP, it must invest in a project that could take years and cost millions of dollars. This might incorporate the following:
- Prototyping and mapping critical business processes in migration
- S/4HANA can be used to adapt legacy applications.
The migration effort will require years of your most valuable resources being committed. This could make it challenging for your business users to innovate and will restrict your ability to draw in new clients. Compared to earlier SAP alternatives, SAP 4/HANA offers less customization. This may affect your unique, customized processes.
SAP S/4HANA Migration Options
Experts at SAP and other tech leaders may be able to offer a variety of ways to handle a switch from SAP 4/HANA. The three that are most frequently suggested are listed below.
Greenfield Approach
The migration option is not the only option. It's a complete SAP implementation services of S/4HANA.
In architecture, the phrase "greenfield" describes beginning a project on undeveloped terrain. For S/4HANA, there can either be just data migration or none at all.You can eliminate legacy customizations and streamline processes.
Full Migration
A complete migration approach is the conversion of an SAP system to SAP 4HANA. This method is often called "lift-and-shift."
Any database from a company that doesn't use SAP HANA can be migrated using SAP Software Update Manager in this case. In order to address the issue of application customization, businesses might use the SAP cloud or SAP partner development tools.
Hybrid Migration
To find specialized apps, functionality, or integrated experiences that are not a part of the core, organizations must assess their present SAP system.
Before the migration, businesses can use a low-code platform to develop the custom components and applications the system needs. It is possible to complete this work in advance to make migration simpler.
Your business can then use S/4HANA to do what SAP excels at--enterprise resources planning--and other applications for what it does not.
Difference between Conversion and Migration in SAP
Technical conversions are a combination release upgrade from SAP ERP and SAP S/4HANA, as well as a migration of the database system from SAP HANA to the current one.
This is a complex and lengthy process that can take an advertising network several days. For several reasons, planning is crucial. You must first understand the current environment and how online behavior works. Also, learn the time required for each phase, mainly if they are time-critical.
Any component of an SAP S/4HANA project can use SAP Activate. This blog post will review the SAP Activate phases of SAP's suggested implementation roadmap for SAP S/4HANA. The tasks that SAP Activate approves are in the work streams. On-premise data migration is handled via the system's data migration workstream. The workstream for data management is for moving data to the cloud.
What is the need for Migration/Conversion?
Migration/conversion is necessary when upgrading from one version to another or transferring data from a legacy system to Oracle Apps. Large amounts of data, occasionally millions, can be transferred from one system to another. Data must be confirmed before being moved. Oracle Apps should only accept legitimate records.
If the data structures of both the target and source systems are different (the tables are not the same/Table Structure is different/The data stored in the database are not the same), then it must be translated. Otherwise, it is called a conversion. Data migration can be described as the reimplementation of an Oracle app version.

Conclusion
The leadership should give close attention to the migration to SAP S/4HANA because it can involve significant financial expenditure. Migration to SAP S/4HANA is unavoidable as businesses must reduce the innovation gap to obtain a competitive advantage. The most recent SAP support update states that the company will extend support for SAP Business One Suite through 2030 and keep providing support through 2027. Before now, SAP had said that ECC support would stop in 2025. This was done to support the clients' businesses since setting up SAP S/4HANA might take more time.
Database compatibility is the main reason. S/4HANA runs only on the SAP HANA database. All subsequent SAP ERP releases will follow suit. The ERP software services flagship version could have run on many databases in the past.
The data migration sub-project should not be viewed as a standalone entity but rather as a component of the larger project. The interconnections between departments and sections influence the structure, selection criteria, transformation procedures, and data checks. To resolve the issues, address the specific inquiries, and modify the specifications for the data migration, the project should be carried out throughout the project.
Early access to the new system is required to properly organize the data in the essential test scenarios and incorporate the data migration into project planning. At first, a preliminary cost planning value estimate may be used.
