Data migration is the process of moving data from one location to another, one format to another, or one application to another. Generally, this is the result of introducing a new system or location for the data. Whilst, application migration is the process of moving a software application from one computing environment to another. You might, for instance, migrate an application from one data center to another, from an on-premises server to a cloud provider's environment, or from the public cloud to a private cloud environment.
Data migration is important because it is a necessary component to upgrade or consolidate servers and storage hardware, or adding data-intensive applications like databases, data warehouses, and data lakes, and large-scale virtualization projects. Data migration may also occur within systems built on HDD or SDD, or between in-house systems and cloud storage.
In DastN you will find the main types of data migrations, each of which requires sufficient planning beforehand and validation afterward
1. Database Migration: Databases often live at the heart of the technologies we use every day. It’s no surprise that SMBs change database vendors, upgrade their software, or move their database to the cloud.
Before migrating databases, companies must include these steps in their plan: (better be as charts)
a- Assess the size of the database.
b-Test applications using the database.
c-Guarantee data confidentiality within the database.
d-Test the migration process for compatibility.
Doing this may reduce hiccups after the migration is complete.
2. Storage Migration: If you’ve ever transferred business data from disks to the cloud, you’ve done a storage migration. Storage migrations are when data is transferred from one storage medium to another.
Technology refreshes are a great time to migrate data. When new technology becomes available, transferring your data to that technology can be attractive because of the efficiency, cost, or experience of accessing and using the data in the new format. Many tools and products are available to ease in migrating your stored data.
3. Application Migration: Similar to a database migration, application migrations take place when companies switch vendors or platforms. Examples include implementing a new HR system or switching from one CRM to another.
Companies migrating applications must make sure their data can be communicated between the two applications. Each application may have a unique data model, so attention must be paid to how that data is formatted. After all, an application is only as good as the data within it.
4. Business Process Migration: Finally, a business process migration is the complex transfer of applications and databases containing information about customers, products, and operations.
These examples are best seen in mergers and acquisitions, business optimizations, and reorganizations.
Data migrations can be easy, but they must be planned for and validated once they’re finished to end on time and within budget. If you need help with data migration, feel free to reach out to us with your case.
