Sunstar Company can help with the movement of your data!
At some point in time a business will choose to take advantage of more efficient storage technologies. The result; move physical blocks of data from one tape or disk to another, often using virtualization techniques.
The data format and content itself will not usually be changed in the process and can normally be achieved with minimal or no impact to the layers above.
It may be necessary to move from one database vendor to another, or to upgrade the version of database software being used. The latter case is less likely to require a physical data migration, but this can happen with major upgrades. In these cases a physical transformation process may be required since the underlying data format can change significantly. This may or may not affect behavior in the applications layer, depending largely on whether the data manipulation language or protocol has changed – but modern applications are written to be agnostic to the database technology so that a change from Sybase, MySQL, DB2 or SQL Server to Oracle should only require a testing cycle to be confident that both functional and non-functional performance has not been adversely affected.
Changing application vendor – for instance a new CRM or ERP platform – will inevitably involve substantial transformation as almost every application or suite operates on its own specific data model. Further, to allow the application to be sold to the widest possible market, commercial off-the-shelf packages are generally configured for each customer using metadata. Application programming interfaces (APIs) are supplied to protect the integrity of the data they have to handle. Use of the API is normally a condition of the software warranty, although a waiver may be allowed if the vendor’s own or certified partner professional services and all tools are used.
