What is meant by Data migration?
The term "data migration" refers to the process of transferring data between different storage systems, formats, or computing environments. This migration may be necessary when companies update their systems, consolidate data, or adopt new technologies. The goal of data migration is to transfer data accurately, completely, and securely from the source environment to the target environment.
Typical software functions in the area of "data migration":
-
Planning and Analysis:
- Assessing the existing data structure and planning the migration.
- Identifying the data to be migrated and defining the migration strategy.
-
Data Extraction:
- Extracting data from source systems.
- Supporting various data sources and formats.
-
Data Transformation:
- Converting data into a format suitable for the target system.
- Applying mapping rules and data cleansing processes.
-
Data Transfer:
- Physically transferring data from the source to the target.
- Ensuring data integrity and security during the transfer.
-
Data Validation and Testing:
- Verifying the completeness and accuracy of the migrated data.
- Comparing source and target data to ensure consistency.
-
Data Integration:
- Integrating the migrated data into the target system.
- Adjusting and linking the data with existing datasets in the target system.
