Exception Handling and Issue Log for Data Migration
Exception Handling in a Data Migration document refers to the systematic process of identifying, managing, and resolving errors or anomalies that occur during the transfer of data between systems. An
Issue Log serves as a detailed record of all encountered problems, including their status, impact, and resolution steps, ensuring transparency and facilitating troubleshooting. Together, these components enhance the reliability and accuracy of the data migration process by providing structured mechanisms to address unexpected challenges.
What data integrity checks are outlined for the migration of legacy system records?
The migration process includes comprehensive data integrity checks to ensure accuracy and consistency of records. Validation steps verify record completeness and correctness after each migration phase. Additionally, checksum and hash comparisons are implemented to detect any data corruption during transfer.
How does the document address data mapping between legacy and target schemas?
The document provides a detailed data mapping strategy linking legacy fields to target schema attributes. Transformation rules and data type conversions are clearly defined to maintain data compatibility. It also includes examples of custom mappings to handle complex legacy structures seamlessly.
What rollback procedures are specified in case of data migration failure?
Rollback procedures involve automated backups taken before each migration batch to ensure quick restoration. In case of failure, the system triggers a defined rollback protocol that reverts changes to maintain data stability. Detailed logs assist in identifying failure points to prevent recurrence during subsequent attempts.
Are legacy data cleansing and deduplication processes detailed?
The document outlines a thorough data cleansing and deduplication process to improve data quality before migration. It specifies criteria for identifying duplicates and erroneous entries using algorithmic and rule-based techniques. Cleansing workflows include standardization, validation, and enrichment steps to enhance data usability.
How is user access and security managed during the migration phase?
User access is strictly controlled through role-based security policies to protect sensitive information. Temporary access privileges are granted only to authorized personnel involved in the migration. Additionally, all data transfers are encrypted, and audit trails are maintained to monitor access and activities.
