In this article, you will learn how the server migration process works and when you should employ it.
What is Server Migration?
Server migration is the process of moving data, such as applications and services, from one server to another. Along with migration, you also need to ensure that the target system is configured correctly so that it can host the new information. By utilizing server migration, you can move from one physical server to another, from an on-premise infrastructure to a cloud-based setup, or between cloud environments.
For example, when migrating a web hosting server, the process involves installing required database software, moving website files, and configuring Domain Name System (DNS) settings. These tasks work together to ensure the website runs smoothly on the new server and customers can easily access it.
When to Migrate Your Server?
The decision to migrate your server depends on the specific circumstances of your hosting environment. Here are key scenarios that indicate it’s time to consider server migration:
- When Your Business Needs Greater Flexibility and Scalability: If your current infrastructure cannot support increasing workloads or expansion goals, you can migrate to a cloud-native platform. This will offer the benefits of scalability and dynamic resource allocation, ensuring your system can effortlessly adapt to growing demands.
- When You Need to Integrate Advanced Technology: Legacy systems might sometimes lack the capabilities to adapt to new tools or applications. By transitioning to an updated environment, you can leverage modern technologies, ensuring your system operates faster and integrates better with current applications.
- When Operating Costs Need Optimization: Maintaining physical servers can strain your budget due to recurring maintenance, repairs, or hardware upgrades. In such a scenario, you can migrate to cloud platforms to reduce upfront expenses. They provide a predictable operational cost budget where you pay only for the resources you use.
Types of Server Migration
There are many different techniques that you can use to migrate your data from one server to another. Let’s look at a few of them:
On-premises to Cloud
In an on-premise to cloud migration, you transfer data, applications, and services from your organization’s on-site server to a cloud environment. This migration helps reduce the burden of physical hardware and infrastructure.
Cross-Platform Migration
A cross-platform migration is moving data and applications between different platforms. Using this strategy, you can move data from physical to physical servers, physical to virtual servers, or virtual to virtual servers.
Database Server Migration
Database server migration involves transferring data from a source database to a target database. After the migration, the client access is redirected from the source to the target database.
Application Server Migration
Application server migration is a process of shifting the application software from one server to another. This process is a part of the broader strategy to upgrade outdated technology to meet modern business standards.
Operating System Migration
Operating system migration facilitates transferring a server from one operating system to another. It is ideal when you want to update the current OS or switch to a new one, such as moving from Linux to Windows.
Server Pre-Migration Checklist
Server migration is more than just data transfer, it’s an opportunity to upgrade the infrastructure. Here are some pre-migration checkpoints that help you establish a foundation for the migration process.
- Define Your Migration Goals: Evaluate your requirements and clearly outline what you want to achieve through migration, whether it’s for performance optimization, cost reduction, or scalability.
- Ensure Compatibility: Run compatibility tests to ensure that the applications you want to migrate will function properly in the new environment.
- Backup Data: Create backups of all the critical data and systems to prevent data loss in the event of incomplete migration or failure.
- Perform Security Audit: Implement necessary data protection measures before and after the migration to safeguard your information.
- Plan Downtime: Schedule migration during a low-traffic period to minimize disruptions to your services.
How to Perform Server Migration?
The following are the five major steps in the server-to-server migration process:
Preparing the New/Target Server
The first step of the server migration process involves preparing the new server. This includes configuring the settings, permissions, and authorizations. You must also determine whether your organization will use any new technology or service; if so, integrate these into the server setup in this step.
Assess Data Fidelity
Losing even a tiny fraction of data can impact the performance of your site or application. Data fidelity is the process of ensuring that all data is accounted for and adequately integrated into the new server during migration. Verify that the critical components and services function correctly.
Data Transfer
Transferring data to a new server can be done using file transfer protocols, cloud migration tools, or third-party migration tools like Airbyte. The speed of data transfer depends on the bandwidth availability; the greater the bandwidth, the faster the transfer.
Quality Assessment
When the migration to the destination server is complete, you must perform a quality assessment, testing the software for any processing issues. It is essential to put the server through rigorous testing to identify any faults. You can document this process and use its findings to determine the best approach to resolving any issues if the server encounters problems.
Change the DNS and Go Live
After completing the thorough testing, the final step is to update the DNS settings. This change directs the traffic from the old server to the new server, ensuring all your users connect to the correct infrastructure.
