Once you understand the basic steps and what to prepare in advance, the entire move becomes much easier to manage.
If you're not fully sold on a Linux VDS just yet, take a look at this blog post explaining why it's the performant solution that's on the rise.
What Most People Get Wrong About Hosting Migration
Let’s start by clearing up a few common misconceptions about hosting migration that often make the process feel harder than it really is.
Thinking Migration Is Highly Technical
Many people assume you need deep system admin skills to migrate to a VDS. In reality, most steps are straightforward, and many hosting providers offer tools or support to guide you through it.
Skipping Backups
Some users think backups are optional if everything is “working fine.” That’s risky. Even a small mistake during migration can lead to data loss, so having a recent backup is non-negotiable.
Not Accounting for Potential Downtime
It’s easy to assume that your site will stay live without interruption. But DNS changes or server setup can cause short downtime, so it’s better to plan for it instead of being caught off guard.
Assuming You Will Get No Help from Hosting Providers
A lot of people think they’re on their own once they start the move. Most hosting providers actually offer migration help in the form of documentation and explainer videos. Some (such as ourselves) even have full transfer services.
Not Having a Testing Framework in Place Post Migration
Some users switch servers and go live without proper testing. This can lead to broken features or performance issues that could have been caught early with a simple testing setup.

What Is a Linux VDS and Why It’s a Smart Upgrade
VDS stands for Virtual Dedicated Server. It’s simply a virtual server that gives you dedicated resources like CPU, RAM, network, and storage, even though it runs on a physical machine shared with other users.
A Linux VDS, then, is any VDS that runs on a Linux-based operating system, such as Ubuntu or Debian. Here’s why it’s a solid upgrade option for people struggling with shared hosting or other restrictive environments:
- You get dedicated resources: Unlike shared hosting, your performance isn’t affected by other users on the same server.
- More control over your environment: You can install software and manage the server any way you want.
- Better performance and stability: With isolated resources, your site or app runs more consistently, even during traffic spikes.
- Easy to scale when needed: As your project grows, you can upgrade your resources without needing to move to a completely new setup.
- Cost-effective step up: It gives you many of the benefits of a dedicated server without the high cost.
The Pre-Migration Checklist
Before you start the actual move, it’s worth taking some time to get a few basics in place. This checklist will help you avoid common issues and keep things on track.
- Check server requirements: Make sure your new Linux VDS meets all the requirements your application needs, including storage, RAM, CPU, and supported software versions.
- Inventory your data: List out everything that needs to be moved, including website files, databases, emails, and any configs you may have set up.
- Audit your current environment: Note key details like your OS version, installed software, PHP or runtime versions, database setup, cron jobs, and any custom dependencies your app uses.
- Create a backup: Take a full backup of your files and databases. Store it in a separate location so you can restore quickly if something goes wrong.
- Define a testing framework: Set up a way to test your site after migration. This could be a staging URL, a hosts file setup, an automated test suite, or a checklist of features you will manually verify.
- Plan DNS and domain changes: Decide when and how you will update your DNS records. Lowering the TTL in advance can help reduce downtime during the switch.

A Step-by-Step Guide to Move to a VDS
With the prerequisites sorted, let’s explore how you can now perform the actual migration. You have two options: Either let your hosting provider take care of it, or do a manual migration yourself.
Host-Managed Migration
- Choose a VDS plan from your hosting provider and request a migration.
- Open a support ticket and share your current hosting details.
- The support team schedules and performs the migration for you. There may be a short maintenance window while the move is completed.
- Once done, they confirm everything is working on the new server.
Manual Migration
- Choose a VDS plan and provision your new Linux server.
- Set up basic access and make sure the server is ready.
- Use your host’s backup or migration tool, or a tool like rsync, to transfer files from your old server.
- Move your database and update your app configuration if needed.
- Update your DNS records to point to the new server IP.
- Test your site after the switch to make sure everything works.
Even if you go with the manual method, most hosting providers still offer support if you get stuck at any step.
What to Do Post VDS Migration
With the migration now complete, here’s a quick checklist to make sure everything is running the way it should.
- Execute your testing framework: Go through the tests you defined earlier and make sure all key features and workflows are functioning properly.
- Link and path audits: Check for broken links or incorrect file paths that may have changed during the move.
- Verify database connections: Make sure that your application is correctly connected to the new database and that data is loading as expected.
- Check performance: Monitor how your site behaves on the new server. Look for faster load times and stable performance under normal usage.
- Review error logs: Check server and application logs for any hidden issues that may not be visible on the front end.
- Secure your server: Set up a firewall and disable unused services to reduce risk.
- Set up regular backups: Configure automated backups on your new VDS so you are covered going forward.
- Monitor uptime and health: Use a monitoring tool or your host’s dashboard to keep an eye on availability and server health.
