A legacy system could be a dated computer, hardware, software technology or a database that’s in use by the business. These systems are difficult to use because they’re built on outdated technologies and have limited capacity for expansion, and do not connect to modern applications and platforms. In most cases, these systems are in use because they serve a purpose for the business and cannot be easily replaced.

Legacy data usually contains inaccurate information, referred to as bad data, or missing mandatory data. It can be difficult to identify the incorrect data and fix it. This can take a long time, particularly when the data has been loaded into a new system numerous times.

It is essential for businesses to move their old data into more modern platforms because these tools are easier to access and more integrated. Modern technology can help ensure that compliance with legal and regulatory standards can be achieved, which is particularly important for companies that handle customer data.

There are a variety of ways for transferring data from older systems to modern systems. One method of moving old data is to run old and new systems at the same time for a few minutes to get familiar with the system and to identify any bugs without losing vital data. Another way is to use middleware, which acts as a translator between the two systems, connecting them so that they can talk to one and each other. This is a cost-effective option, but it requires a long mapping between the systems.
