ERP is a “mission-critical” application for any business as it incorporates all the individual division functions into a solitary software application. It not only accelerates your tasks but also turns out to be more productive in accomplishing your business objectives. The teams are connected to an integrated system, tracking the workflow of each department, decreasing operations costs or avoiding discrepancies.
While having ERP gives you many advantages but implementing that ERP on-premise has its own spiral of issues.
Is it flexible, or capable of providing scalability or flexibility within minutes? Also, how reliable is it?
None, moreover the implementation of an on-premise ERP takes much longer than a cloud ERP and equipment cost and maintenance costs as well. Also, many organizations have found that cloud ERP is much friendly and reliable.
Cloud computing — with its great framework, adaptability, and cost-productivity — is the best option for each organization that is progressing towards evolving digital economy. Some of the pros of Cloud ERP are:
- Flexibility and scalability
- Disaster recovery
- Mobility – Work from anywhere
- Increased collaboration
- Agility – Faster Time to Market
- Capital – expenditure Free
- Increased collaboration & Document control
- Environmentally friendly
Today the primary issue here is: “When are we migrating the SAP to the cloud, and how are we going to do it?” Though, the continuous progress in the same appears to be overwhelming. Thus, most organizations still haven’t figured out their migration to cloud process.
Migrating your current SAP to a cloud is a complex undertaking. We have specialized in providing SAP system integration services. We evaluate infrastructure readiness and can help your enterprise understand business challenges to define an SAP Data Migration Strategy and solution roadmap.
Visual Representation of the SAP Migration Mind Map
The given roadmap for the SAP Migration is mined out from the best complex migration projects and is applicable to any SAP migration project. This mind map will give you a deep insight into the workings of the SAP data migration Strategy and its guidelines.
Discover & Assess
Discover and Assess Process takes a shrewd review and inspection of the environment and its interdependencies. Surveying, prioritizing and assessing the systems and figuring an all-inclusive strategy for migration. It is critical to assess your IT Landscape while making your migration plan. It encourages you to understand the most extreme advantage of this investment while diminishing the long-term total cost of ownership. Insufficient and over-provisioned estimating could lead to unforeseen postpones that will expand the cost of operational execution.
The objective is to make the blueprints of the assets and expenses of the migration alongside the resulting savings.
It is imperative to have a planned SAP Migration Strategy with asset allocation and required SAP migration tools to smoothen the migration process. We plan the Testing, Validating, and Cutover; the unpredictability of moving existing applications varies on the design and existing permitting plans.
Migration is a consistent improvement approach, we begin with slightest complex applications, towards the more unpredictable application. We coordinate the design Roadmap, implementation and migration plan.
Following two are the most commonly used SAP Data Migration techniques:
- Classical migration: This is the most used migrations approach for OS/DB migration, that is, a heterogeneous system with SAP migration tools such as SWPM, R3load and Migration Monitor.
- Database Migration Option (DMO) of SUM: This migration approach reduced the manual efforts as compare to other migration techniques and one business downtime period. This approach offers the least erroneous simplified steps of SAP data migration.
While migrating, the focus moves onto each application designed, moved, and approved by one of the 5 (Re-hosts, Replace, Retire, Re-platform, Retain) application migration techniques.
- Re-host (also known as lift and shift)
Re-hosting is currently the most common migration method due to its simplicity, speed, and cost optimization. In this, the applications and data bits are copied from outside the cloud into the cloud without any code modification. Basically, we will migrate Virtual Machines (containing applications & data) or storage files (only data) to the cloud.
This approach treats the cloud as a data center; however, you will not get much out of cloud services.
- Re-platform (also known as lift and shape)
Re-platforming is a slower migration approach than re-hosting. In this approach, the migration is done to the few immediate clouds by not modifying the foundation of the application but migrating more managed services or alternative licensing. The ‘shaping’ here is we move the data to the cloud while moving the database is being handled by the RDBMS.
This approach makes the application more cloud compatible but not cloud-native.
Replacing approach completely replaces the ERP to software delivered as a service (SaaS). Although there is a probability of issues in accessing information, unusual data semantics, however, this approach helps in increased cost savings.
- Retire (also known as decommissioning)
While planning your SAP migration strategy, we do a step called discovery to prioritize the application as per their usability. There are some processes that are not being used but take costs and resources of the ERP. This approach decommissions those applications saving resources and increasing costs savings.
- Retain (also known as re-visit)
On the step to discover and assessment, we find some applications that are not compatible with the cloud environment as they may have high business criticality and high complexity due to extreme interdependencies. They are either recently optimized to work on on-premise ERP or they are going to be decommissioned soon.
In this case, there is no much ROI that allows us to migrate them to the cloud, and we retain them in the present state and reconsider later.
In the end, we perform the end to end testing of all the vital business processes and production. There is a choice to do the testing either at this stage or after the production data migration and cutover step. This is a mandatory step required and shouldn’t be skipped.
The bottom line is, SAP Migration requires insightful strategy and the given mind map has been a proven approach. The focus of the SAP data migration strategy is streamlining the workload to the cloud by managing each task with the teams, processes, and tools while each working through a prioritized list.
Finally, the application is can be resumed on the new systems of the new foundation. Kill the old frameworks, and continually emphasize toward a cutting-edge working model.
