Data migration refers to the process of moving information from one type or format to another. This is often done when a business' systems are upgraded or when two companies merge. The process is normally automated, but it can be done by hand also. To reduce the issues and facilitate the process, the old data is first mapped into the new system and then transferred. If done correctly, both systems will operate comparably, and there will be a minimal loss of data.
In a business, storage migration is perhaps the most common type of data migration, and it is by far one of the easiest. This often consists of moving data and files from a smaller storage space to a larger one. Data and information is rarely lost in this process because no conversions need to be completed with the files. The biggest risks for loss of information are present when converting from one type of media to another such as from a physical format to a digital one.
Another type of data migration that is used would be application migration, and it is more difficult than the type mentioned previously. The difficulty occurs because applications are very unique in how they work and how they are programmed. Normally for application migration to be successful the application will need to be entirely rewritten. The new application should be functional on many different platforms in order to have the widest market which means that additional testing will be necessary.
Perhaps the most difficult type of data migration is database migration. It is more probable that some data and information will be lost during database migration because of the quantity of data that needs to be transferred. The migration from Oracle to Postgres is one of the most common but also one of the hardest to complete effectively. This is because the two source codes are very different and will not behave in the same way. This kind of data migration can be very time consuming because the new source codes will need to be tested and retested many times to ensure proper functionality.
Data migration is needed for many reasons in a business. It is inevitable that systems will need to be upgraded and information will need to be reformatted and moved to the new system. The process can be expensive, hard, and time consuming depending on what needs to be done and who is completing the job. Employing a specialist to manage the process is usually the best move to ensure that the data migration goes through with minimal problems and best results.
