Dealing with challenges is chaotic. Businesses today are actually involved in solving puzzles of how to drive actionable decisions, how to streamline operations, and even how to improve customer experiences. The answer to these questions lies in legacy data that might be stored in an outdated system, software, or obsolete formats.
So, the need is to convert legacy data. Do you know how? Well, data conversion companies can answer it better. But first, let’s introduce you to legacy data migration.
What is Legacy Data Migration?
The term legacy data migration points to shifting data from an out-of-date system to a modern or advanced system. Typically, professional companies use scalable and user-friendly interfaces. This is simply because this transition of records might involve the movement of older databases, which might be on paper. Or, it can be shifting data from custom-built software to cloud-based platforms, servers, or customer relationship management (CRM) tools.
This shifting became a need of the hour, and a report by Gartner proves it, which states that 87% of organizations found that their legacy systems interrupt their digital transformation. That’s why it’s necessary to convert data.
Key Challenges in Legacy Data Migration
The migration or shifting of legacy data can be tedious. It involves understanding its complexity, managing its volume, and ensuring compatibility with new systems. Basically, the associated challenges can range from these:
● Data Integrity and Quality: Being legacy data, it can be stored without any consistent format or completion. The data might be corrupted. So, the foremost challenge is to transform it into an accurate and integrated database during migration so that it won’t sound erroneous. Nor does it get lost.
● Data Formatting: The word legacy triggers a panic button as legacy data might be in a format that the new system won’t understand or won’t be compatible with. So, the data conversion companies have to deal with their formatting challenges.
● System Downtime: Migration is a lengthy process, and downtime makes it longer. This challenge can hamper business operations, and hence, badly affect productivity.
● Complexity of Data Mapping: Before migration, a thorough understanding of that data should be done. Map it and decide how it is going to be shifting from one system to another. Prior planning and expertise are a must before actually transferring the data. This brainstorming will help in understanding diverse data structures and how to simplify the process.
● Scalability: Scalability is the flexibility to scale up or down the data according to future growth. This is the real challenge, as the new system must be able to accommodate the current data. Also, it should have the ability to handle future requirements.
How Data Conversion Companies Address These Challenges?
The aforesaid challenges require proper administration. That’s why data conversion companies are hired. They use a systematic approach to migrate any type of data. For legacy datasets, it employs a combination of methods, technologies, and best practices. So, here comes the best approach to handle the whole process.
1. Assessment and Planning
The very first step is to understand and thoroughly analyze the data before migration. The evaluation encompasses existing legacy systems, data structure, and potential threats. These three aspects are crucial because every legacy system is unique, and a one-size-fits-all approach does not work well in this case.
Additionally, the scope for migration should be well-defined. For it, the data specialists and IT teams identify data to be shifted, timelines for diverse stages, and resources required. Moreover, discovering risk factors is also necessary to foresee potential challenges and how to combat them effortlessly.
2. Data Cleansing
Once every need is recognized, kickstart cleaning the legacy data. Analyse and find incomplete, outdated, and corrupt records. Professional companies use specialized tools to automatically detect and cleanse them. Then, they run a defined validation process before migrating them. This is how they eliminate dupes and formatting issues and shift transformed data.
3. Data Mapping and Transformation
Now that cleansing is done, data mapping is aligned. Many data conversion companies map data from the old system through to the journey to the new one. It may involve data from different sources and formats to be integrated seamlessly. In the meantime, transformation takes place, which requires data types (like PDFs into digitized files) to be converted, restructured, & enriched. These processes help in transforming legacy files into compatible data with the new system.
Consider the case of a legacy CRM system that consists of different fields if compared with a modern CRM platform. The conversion specialists easily discover these fields so that customers’ details can be accurately shifted.
4. Testing and Validation
As the migration process is all set to run, you need to test the process. It cannot be done blindfolded. So, extensive testing is conducted while measuring the accuracy, completeness, and functionality of data within the new system.
Once the data has been mapped and transformed, it’s time to test the migration process. Data conversion companies conduct extensive testing to ensure that the migrated data is accurate, complete, and functional within the new system. Testing might involve validating data integrity, checking for data loss, and confirming that the new system performs as expected.
Overall, the conversion specialists confirm that the entire process continues to go on. If there emerge any issues, the company will be able to resolve them before migration because it knows its ins and outs.
5. Data Migration Execution
As the test is over, the actual migration starts. Instead of going at once, it can be split into stages, depending on the size and complexity of the data. Considering the shifting of data, the technicians do it either manually or automatically.
The possibility of longer downtime is there during this procedure. So, the expert companies follow a process called parallel migration, where both the legacy and new systems are aligned to run in parallel to each other until the shift is over. This is the best migration practice, and it does not hamper business operations during migration.
6. Post-Migration Support
This is a support stage, where data conversion companies provide post-shifting support so that the new system’s smooth functioning can be consistent and agile. If any problem emerges, these professionals resolve it immediately via troubleshooting, training, and bringing changes to the new system as per feedback.
Final Note
In a nutshell, the best practices for legacy data migration involve prior planning to avoid risks and a smooth transition. All stakeholders from various departments are informed so that business goals and needs won’t be compromised. The professionals emphasize that the data remain integrated throughout the process, which means there are no errors or discrepancies in the new system. To ensure that the shifting is done properly, testing is carried out.
