Big Data Migration: Import/Export

In this chapter

This chapter explains how to transfer big data between QueryIO server and other data sources.

What is Big Data Migration

Data migration is the process of transferring big data between storage types, formats, or computer systems. Data migration is usually performed programmatically to achieve an automated migration, freeing up human resources from tedious tasks. To achieve an effective data migration procedure, data on the old system is mapped to the new system providing a design for data extraction and data loading.

QueryIO provides data migration services from and to different data stores. It provides two services:
