The phrases “database conversion” and “database migration” are sometimes used interchangeably, however they’re two totally different processes that play a giant position in a company’s software program implementation.
What Is Knowledge Conversion?
Database conversion includes pulling knowledge from a now not helpful database, changing it from the unique format to a completely helpful format and propagating it into a brand new, extra applicable occasion. The goal database determines the format that the information will take as soon as transformed.

- Analyze the originating supply knowledge, together with the goal database.
- Design a plan based mostly on the undertaking necessities and desires of the top person.
- Take a look at the conversion in no less than three iterations and high quality examine the outcomes.

The complexity surrounding database conversion actually stems from the necessity to perceive the originating supply and the brand new format. With out this information, the consequence may be compromised knowledge or ruined knowledge integrity. Different frequent points embrace duplicate knowledge, which can have to be merged; out of date knowledge, which is able to have to be deleted earlier than conversion; and incorrect knowledge, which can consequence within the want for a guide repair.
What Is Knowledge Migration?
Whereas database conversion is principally the transformation of information from one format to a different, database migration is the method of shifting knowledge from one supply, format or system to a different. Knowledge migration often requires high quality assurance processes by the goal supply, corresponding to knowledge validation, cleaning and profiling.
Most organizations want database migration once they improve their methods or start utilizing a cloud answer. There are three primary kinds of migration: storage, cloud and utility. Storage migration is the method of shifting arrays of information from deprecating (getting old) databases into extra fashionable variations to allow entry by a more moderen system. Cloud migration refers to shifting knowledge from one cloud occasion to a different or from a knowledge heart to a brand new cloud. Software migration is shifting a complete utility from one location to a different or shifting its current knowledge to a brand new model of the applying.
Knowledge Migration Course of
The method of information migration includes reviewing the database because it at present stands, knowledge mapping to search out potential inconsistencies or discrepancies, transferring the information to the brand new database and, lastly, testing to make sure all knowledge is migrated accurately.

At first look, database migration could seem easy, however it’s truly fairly complicated. The brand new system will need to have matching fields for the present knowledge; in any other case, it may be misplaced within the migration course of. The method required to make sure that knowledge units are correctly mapped throughout a migration is mostly carried out prior as a part of database conversion. Correct planning earlier than performing a database migration is vital to assist scale back the prospect that points will come up.
Outsourcing Knowledge Conversion and Migration
