Data Migration in the ERP Migration Process is a critical aspect of successful
Data Assessment and Planning:
- Thorough assessment of existing data helps identify the data types, volumes, and quality in the current ERP system.
- Categorize and Classify data according to its importance, relevance, and sensitivity to prioritize the migration of data sets.
- Plan data mapping by defining how data from the old system will be mapped to the new system's structure. This includes fields, formats, tables and any necessary transformations.
Data Cleansing and Quality Assurance:
- Cleanse data by identifying and rectifying any inconsistencies, errors, or duplications in the existing data.
- Validate data quality to ensure that data meets the quality standards required for the new ERP system.
- Establish data governance by implementing policies and processes to maintain data quality over the period of time.
- Develop a strategies for extracting data from the old ERP system to new one. This may involve using tools, scripts, or APIs provided by the ERP or third party vendors.
- Verify that data is extracted in a consistent manner to avoid discrepancies during migration.
- Convert data from the format used in the old ERP system to the format required by the new ERP system.
- Address any discrepancies in data models, structures, or business rules between the old and new ERP systems using test environments.
- Load data sets instead of complete data at a time to minimize downtime and disruption.
- Conduct trial loads to identify and resolve any issues before the actual migration.
- Test the migrated data thoroughly to ensure accuracy, completeness, and integrity.
- Don't shut down the old ERP system immediately but run it with the new ERP systems in parallel for some time. It helps identify and address any discrepancies in real-time operations.
Backup and Rollback Plan:
- Ensure that comprehensive backups of the data are taken before migration to mitigate the risk of data loss.
- Develop a rollback plan to revert to previous state, in case of issues during and after migration.
User Training and Communication:
- The most important part of any transformation is change management, means to mentally prepare affected users to adopt a new environment.
- Training users on the new ERP system to address changes in data entry or retrieval processes is very important.
- Communicate changes by keeping all stakeholders informed about the migration process, its timeline, and any expected disruptions.
Post-Migration Support & Documentation:
- Having a support plan in place to address any issues that may arise after migration is necessary.
- Continuously monitor the performance of the new ERP system to capture any malfunctioning and make optimizations as needed. Documenting the processes helps for future reference and audits.
Data Migration in ERP Migration Process needs carful planning and execution. Organizations can minimize risks, ensure data integrity, and achieve a successful transition to the new system in collaboration with their partners.
