Data migration is the process of transferring data from one source to another system. As many companies look to migrate their data from their on-premise data warehouses to the cloud, find out what the best data migration tools are.
Within an enterprise, data migration consists in transfer data from one source to another system. Most often, a data migration is carried out as part of an infrastructure change. For example, when a company decides to move to the Cloud, it needs to transfer its data from its on-site Data Warehouse to the Cloud.
Similarly, if one company acquires another, it will be necessary to transfer the data to the acquirer’s Data Warehouse. In addition, when a system becomes obsoleteIn many cases, it is necessary to transfer the data to a newer system. Finally, it may also involve transferring data from one department to another.
Data migration: what are the different types of tools?
Data migration is carried out using tools designed for this purpose. There are three main categories: on-premise, open source, and cloud-based migration tools.
On-premise data migration tools are designed for the data migration within the internal network of a company. They allow data to be transferred between several servers or databases without going through the Cloud.
These tools are ideal for Data Warehouse changes, or for bring together data from different sources. Some companies prefer on-site data migration for security reasons.
Among the best on-site data migration toolsThese include Centerprise Data Integrator, Informatica PowerCenter, Microsoft SQL, IBM InfoSphere, Oracle Data Service Integrator, and Talend Data Integration.
Open Source Tools
Open Source data migration tools have the advantage of being developed by the community. In fact, they are generally cheaper than commercial solutionsor even free of charge. Moreover, many commercial solutions are based on Open Source products.
This type of tool can be ideal for the smallest and least complex projects. However, Open Source solutions often require computer code skills. Among the best are Apache NiFi, Myddleware, CloverETL, Pentaho and Talend Open Studio.
The last category of data migration tools is Cloud tools. They allow to transfer data from different sources to the Cloud. These may be on-site sources, or other cloud sources.
These solutions are ideal if you want to move to the Cloudor if you are already storing data in the Cloud and want to switch providers. In many cases, storing data in the cloud can reduce costs and increase security. Some of the best cloud data migration tools include Snaplogic, Matillion, Stitch Data, and Fivetran.
How to choose the best data migration tool?
To choose the best data migration tool, you should first of all determine your needs. First of all, choose whether you want to migrate your data on site, or to the Cloud.
In addition, if your priority is keep costs to a minimumIn the case of the “Open Source” tools, it is preferable to use Open Source tools provided that qualified experts are available. Cloud tools also save money, since you will not need your own infrastructure.
Another criterion to be taken into account is the type of data you want to transfer. In general, Cloud tools are compatible with more different models. And if you need to transform your data (enrich, merge, or cleanse), again, it’s best to go to the Cloud.
Finally, if the data you wish to transfer is sensitive or subject to regulations such as the DPMR, the Cloud is generally the best option. The Cloud tools offer a high level of security, and compliance with applicable laws..
