Data migration is the process of transferring data between storage types, formats, or computer systems. It is a key consideration for any system implementation, upgrade, or consolidation. We can develop new programs or use existing systems like ETL to perform these services. We also perform data verification and cleaning as part of this service. Automated and manual data cleansing is commonly performed in migration to improve data quality, eliminate redundant or obsolete information, and match the requirements of the new system. Data migration phases (design, extraction, cleansing, load, verification) for applications of moderate to high complexity are commonly repeated several times before the new system is deployed.
Data migration services fall into different categories: STORAGE MIGRATION, DATABASE MIGRATION, APPLICATION MIGRATION, BUSINESS PROCESS MIGRATION
A business may choose to rationalize the physical media to take advantage of more efficient storage technologies. This will result in having to 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.
Similarly, it may be necessary to move from one database vendor to another, or to upgrade the version of database software being used. We offer migration services for all major databases, relational (Oracle, MySQL, MS SQServer, DB2, PostgreSQL and Sybase) or non-relational (MongoDB, CouchDB, Cassandra, XMLDB, Salesforce, Lucene/Solr/ElasticSearch).
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. Application programming interfaces (APIs) are supplied to protect the integrity of the data they have to handle. Our service professionals have experience in all kinds of APIs and can offer a smooth transition between systems.
Business processes operate through a combination of human and application systems actions, often orchestrated by business process management tools. When these change they can require the movement of data from one store, database or application to another to reflect the changes to the organization and information about customers, products and operations. Examples of such migration drivers are mergers and acquisitions, business optimization and reorganization to attack new markets or respond to competitive threat.
