A server upgrade can look like a simple step forward until a website stops working, an application breaks, or important data fails to transfer as expected. These issues can turn what should be a smooth upgrade into a stressful business disruption.
Moving to a dedicated server can feel like the obvious next step when a business starts outgrowing its current hosting. Yet, the migration itself can create new problems if files, databases, applications, DNS records, or security settings are overlooked.
A server migration is more than moving website files from one machine to another. Businesses also need to consider software compatibility, backups, email, databases, applications, traffic, and what happens if something goes wrong during the switch.
Webpundits provides dedicated server and hosting solutions for businesses with different infrastructure requirements, including servers with dedicated resources and multiple operating system options. If you are asking what you should know before migrating to a dedicated server, careful planning should come before the actual transfer.
Key Takeaways
- A dedicated server migration involves more than transferring website files.
- An audit of the existing server assists in selecting appropriate resources according to the load.
- Backups will ensure protection of business information in case of some problems occurring.
- Compatibility between software, databases, and operating systems has to be verified before migration occurs.
- It is essential to perform testing of DNS, emails, SSL, and other third-party services integration.
- Staging tests will reveal any possible issues of the application and its configuration before migration occurs.
- Downtime planning and rollback plan creation may help avoid disruptions during the process of migration.
- Post-migration monitoring is required to find out performance, security, and application issues.
Why Should Businesses Plan a Dedicated Server Migration Carefully?
A dedicated server allows a company exclusive use of the physical server’s resources. The company thus has control over the CPU, memory, storage, server configurations, and OS configurations.
Nevertheless, a change of environment does not mean the application will be any faster or more reliable. There are instances where the application is badly configured, or there might be outdated databases or services that are required.
Before you migrate to dedicated hosting, start by documenting what currently runs on the existing server.
Check:
- Website files and databases
- Operating system and software versions
- PHP, Python, Java, or other required runtimes
- Cron jobs and scheduled tasks
- APIs and third-party integrations
- SSL certificates
- Email services
- DNS records and subdomains
- Firewall and security settings
- Storage and bandwidth usage
What Are the Biggest Mistakes Companies Make Before Migration?
1. Choosing the Server Before Checking Resource Requirements
This mistake lies in basing the selection of your server only on the number of CPU cores, RAM size, or the cost.
The first step is to check how much you use the resources currently. Examine your maximum CPU usage, RAM usage, storage space, bandwidth, databases, and site traffic.
The needs of a business with a heavy database will differ from those of a business with multiple small websites.
2. Moving Data Without a Verified Backup
However, having a backup does not mean that the business will be able to recover if the migration fails.
First, make sure to back up important information prior to migration and test that the backed-up information is restorable. Make sure to keep the backed up information separate from the system that you are migrating.
This includes:
- Website files
- Databases
- Configuration files
- Email information if any
- DNS information
- SSL certificates and their configuration
In case something goes wrong during the migration process, a recent backup is helpful.
3. Ignoring Software Compatibility
There could be a situation where the new server is running a different operating system, control panel, database version, or software stack.
For example, an application developed using an outdated PHP version will not work once transferred to a server with a more recent version. Other similar problems will occur with databases.
It is important to make a list of the software and their versions prior to the migration process and verify that they are compatible with the new server.
4. Forgetting DNS and Email Settings
Companies tend to concentrate on getting the site up and running without realizing that DNS is responsible for much more than the primary domain.
Review:
- A records
- AAAA records
- CNAME records
- MX records
- SPF
- DKIM
- DMARC
- Subdomains
The absence of an email record could result in emails not being delivered to the right mail server while the website itself is fully operational.
Planning DNS changes before the final cut-over will make sure that the records to be changed are known in advance.
5. Going Live Without Testing
Testing the new server before changing live DNS is essential.
Do not limit testing to the homepage. Check the parts of the business that customers and employees actually use.
| Area | What to Test |
| Website | Pages, images, forms, links |
| Database | Queries, connections, data |
| Login | User authentication and sessions |
| Sending and receiving | |
| SSL | HTTPS and certificate validity |
| APIs | External integrations |
| Cron jobs | Scheduled processes |
| Performance | CPU, RAM, storage and response time |
| Security | Firewall and access rules |
Testing gives the team an opportunity to find problems while the old environment is still available.
6. Underestimating Downtime
However, even with careful planning, it might become necessary to stop changes and redirect traffic for some time.
Companies need to find a proper migration window according to the traffic schedule of their websites. For example, if there is a large traffic volume in the evening, the migration should be carried out at another time.
In the case of more complex applications, it will be possible to prepare the new server while the old one operates.
7. Having No Rollback Plan
What happens if the database fails after the DNS change? What if an important application does not work? What if customers cannot log in?
A rollback plan answers these questions before they become urgent.
The old server should remain available until the new environment has been tested and monitored successfully. The team should also know who can make the decision to return traffic to the previous server.
What Should Be Included in Your Server Migration Checklist?
A useful server migration checklist can keep the process organized from beginning to end.

How Can Businesses Reduce Problems During Migration?
Following established server migration best practices can reduce the chance of unexpected issues.
To begin with, you should always prepare for the migration, not to start doing it immediately. For proper migration, you need to prepare the existing environment, test the new server, and assign the roles for each participant of the migration.
It is also recommended to perform migration in several steps. First, you will need to build the new environment, then migrate the data, check them, and finally move the live traffic.
The security aspects are also crucial in the process of migration. Check your firewall settings, users’ accounts, access permissions via SSH, software updates, and backup configurations on your new server before you start working with it.
One more thing you should definitely take care about is performance. Despite the fact that the dedicated server provides much more resources, you might still need to optimize your applications.
