What is Server Migration? Benefits, Process, and Tools

Want to shift your databases from one server to another? But don’t know how? Don’t worry! In this blog, you will learn what is server migration, its benefits, and its importance. Along with this, I’ll show you the steps used for server migration and the tools that will help you smooth this process. Let’s start!

Server Migration Meaning

You can understand the meaning of server migration by simply separating the words. Here, server means browser, and migration means shifting; they together become shifting from one server to another.

In simple words, the process of moving files, applications, emails, and databases from one server to another is called server migration. It is like changing an older mobile phone with a newer one. It is the same as if you transfer all your photos, videos, and documents to the new mobile. However, for server migration, it is not just about copying and pasting the files, but it is used for transferring complete database, which includes user accounts, configuration files, and security settings. Server Migration aims to switch to a new server with minimal or no interruption for a smooth transfer process.

Benefits of Server Migration

It is like shifting from an older house to a newer one with updated facilities. Server migration helps in adapting to new technologies and ensures the smooth running of the functions. Let me tell you some of the key benefits of server migration.

Performance enhancement: As the older server slows over time, upgrading to a newer version will help increase performance. This results in faster app loading and more memory.
Cost reduction: The old server needs regular maintenance and repair, which increases the investment cost. New cloud servers like Google Cloud and AWS provide you with the facility of paying only for what you use. It cuts infrastructure costs by up to 40%.
Increased security: The updated server provides better security than the older ones. It helps with data encryption, virus scanning, and firewalls. It reduced the risk of hacking and data loss.
Updated technology: The new version of the servers provides automatic backups and quick recovery of the data, as older versions crash more often than the latest versions.
Smarter maintenance: Many new providers come with automated systems that don’t need frequent updates. This means less time wasted on updating and fixing the old hardware problems.
Improve Business value: These new servers are made based on the newer government rules and regulations. It helps in meeting the government rules and policies.

Challenges in Migrating the Server

Migrating the server looks easy, but it is a challenging process. These are some of the biggest and most frequent challenges faced by the users.

Website’s Downtime: When all the database and security configurations are being moved from one server to another, it slows down the website. This results in a website or app crash. For e-commerce businesses, a short downtime can cause customer and financial loss.
Data Loss: While moving a large set of data, records, and documents, some of the data and information can get damaged or lost. It is very risky for customers or finance-based companies.
Compatibility Issue: One software, website, or application that was working perfectly on the older server may not be compatible with the newer version.
Expenses: You may need to pay more than expected based on the data transfer fees, expert help, time required, and tools.
Complexity: Shifting everything without damaging any connection is very risky, as the server is made using many connected parts like databases, user logins, security, and emails.
Security: While migrating, hackers can steal your data if you are not using proper protection and security encryption.
Insufficient Planning: Many people waste huge amounts of money because of mistakes and delays. A person needs to understand the time, money, and other expertise required to execute a proper implementation.
Testing: Once everything is completed, the final step required is testing. This is needed to find and fix the issues for the smoother functioning of the server.

What is the Server Migration Process? Step-by-Step

Let’s understand the step-by-step process of server migration.

Step 1: Planning and assessing

Cross-check everything present on your older server, like websites, databases, emails, files, and apps.
Choose what features you are looking for.
The best time to migrate is usually in the evening or on weekends.
Make a list of the estimated time and possible risks that you can face.

Step 2: Backup

Complete your backup on your old server. This is an important step so that you can restore everything without leaving anything behind.

Step 3: Prepare your new server

Purchase and create a new server on the cloud.
Install the plugin software that will help in configuring your server.
Customize the settings according to the operating system, software, and security settings.
Take an overview of the rules, storage, and networking.

Step 4: Transfer the data

Copy all the database, files, applications, and security settings from the old server.
Use tools like Robocopy and rsync for migrating the data. This process can take time depending on your file size.

Step 5: Migration and configuration

Shift your certificates, user accounts, websites, and apps to the new server.
Update the database based on your new location.

Step 6: Testing

Test your new server by running your app or website.
Check if everything is done as you wanted. Run a speed test, login, emails, payments, and other additional features.
Fix any problems that have occurred before starting to operate the server.

Step 7: Go live

Switch the traffic from the old server to the new one.
Use a DNS setting or a load balancer for this. Focus on minimizing the server downtime.

Using these steps effectively and efficiently will help you to onboard to the new server, that too without any problem and data loss.

Server Migration Checklist

Here, in this section, I have mentioned the checklist for every stage of server migration. Check before proceeding.

Phase 1: Planning (Before Migration)

Make a list of all the data, websites, files, emails, applications, and more from the old server.
Decide on the new server. It can be Google Cloud, AWS, Azure, and more.
Check the functionality and compatibility, such as the operating system, version, and hardware requirements.
Take a full backup of the server and test the backup for any flaws.
Set up the new server

Phase 2: Migration and Configuration (During Migration)

Transfer the files, databases, and security settings.
Sync after the last changes.

Phase 3: Testing

Test apps and websites on the new server.
Check the login process, payment, emails, and file loading speed.
Test the speed and performance of the new server.
Most important thing! Check the security system of the server.

Phase 4: Live

Update your old DNS to point to your new server for the customers.
Send a notification to the team and the customer about the shift.

Phase 5: Post Migration

Monitor your website for the first 24 hours.
Check for any issues or missing data.
Test the speed and resources.
Update details like passwords, security, and documents.
Teach your team and customers to use the new server.
Turn off the old server after 5-7 days of moving to another server.
