Legacy systems may also cause head aches if that they lack full functionality or perhaps require extraordinary software to access the data.

It could be tempting to simply cover the challenge by using suggestions to allow applications to use the legacy database that it had been current. However , this method can result in performance challenges caused by info type modification and limits on the range of indices that can be suitable for a schema. It can also make additional concerns, such as introducing inconsistent important determination approaches or seclusion of trestle tables.

A better alternative is to build an ETL (extract, transform, load) process that copies the legacy repository to a new system.
