Introduction to Data Migration and Key Considerations Before Embarking on Data Migration
Data migration is the process of moving data from one system or platform to
another. In the context of enterprise resource planning (ERP) systems, data
migration involves transferring data from an old or legacy ERP system to a new one.
This can be a daunting task, as ERP systems are complex and contain vast amounts
of crucial business information. During an ERP system upgrade or change, the task
of migrating data from the existing system to the new one is intricate and requires
careful planning. The goal is to ensure that valuable business information is
transferred seamlessly, without loss or corruption, to maintain business continuity.
Key Considerations Before Embarking on Data Migration
- Comprehensive Data Audit:
Before initiating the migration process, conduct a thorough audit of existing data.
Identify redundant, outdated, or trivial information that can be excluded from the
migration, reducing clutter and streamlining the process.

Understand the data structure of both the old and new ERP systems. Map the data
fields and classifications to ensure compatibility and consistency, preventing data
discrepancies in the new system.
- Data Cleansing and Standardization:
Cleanse the data of any inaccuracies or inconsistencies. Standardize data formats,
naming conventions, and units to align with the requirements of the new ERP
- Backup and Data Security:
Prioritize data security by creating comprehensive backups of the existing data.
Implement encryption and secure transfer protocols to safeguard sensitive
information during the migration process.
Types of Data Migration Strategies
There are several types of data migration strategies that organizations can employ
when transitioning to a new ERP system. Each strategy has its own benefits and
challenges, and choosing the right one depends on various factors such as the size
of the organization, complexity of data, and time constraints.
- Big Bang Migration:
This strategy involves transferring all the data from the old system to the new one
in a single go. It is considered a high-risk approach as any issues or errors in the
migration process can cause significant disruptions to business operations.
However, this method is often favored by smaller organizations with less complex
data as it allows for a quick transition.
- Phased Migration:
In this strategy, data is migrated in stages or phases rather than all at once. This
allows for more control over the process and minimizes risks associated with big
bang migration. It also gives organizations time to test and troubleshoot any issues
before moving on to the next phase. However, this approach can be time-consuming
and may require additional resources.
- Parallel Adoption:
Also known as dual-running or shadow mode migration, this strategy involves
running both old and new systems simultaneously for a period of time until all data
is transferred successfully. This ensures that there are no disruptions to business
operations during the transition period but may require additional costs for
maintaining two systems at once.
- Selective Data Migration:
Selective data migration involves transferring only essential or relevant data to
the new ERP system while leaving behind outdated or redundant information from
the old system. This approach can save time and resources, but it requires careful
planning and analysis to ensure that all necessary data is migrated.
- Retire and Replace:
In this strategy, the old system is retired and completely replaced with the new
one without transferring any data. This approach is only suitable for organizations
with minimal historical data or those looking for a fresh start. It eliminates the
need for data migration but may lead to loss of important information.
Overall, the best data migration strategy will depend on an organization’s unique
