Migrating your website and data from an old Virtual Private Server (VPS) to a new one can be a nerve-wracking process. The risk of data loss, downtime, and performance issues is high, especially if you’re managing a complex environment with a control panel like CentOS Web Panel (CWP).
The good news is that with a structured plan and the right tools, you can perform a smooth and seamless migration. This guide will walk you through the entire process, ensuring a safe transfer of all your sites, databases, and configurations without a single hiccup.
Phase 1: Pre-Migration Checklist – Your Preparation is Key
Before you even log into your servers, a little preparation will save you a lot of headaches. Don’t skip these crucial steps.
1. Back Up Everything
This is the most important step. A full backup is your safety net. Use CWP’s built-in backup feature to create a full system backup. This includes all account files, databases, and email configurations. Download this backup to your local machine or a separate storage location.
2. Ensure Server Consistency
For a smooth migration, your old and new servers should be as similar as possible.
- Operating System (OS): The new VPS should have the same OS version (e.g., CentOS 7 or CentOS 8) as your old server.
- Control Panel Version: Ensure you install the same or a very recent version of CWP on the new server.
3. Gather All Necessary Credentials
You will need the following information for both your old and new VPS:
- Root user password or SSH key access.
- Hostname and IP addresses.
- CWP Admin username and password for both servers.
Phase 2: Setting Up the New VPS
Now that you’ve prepared, it’s time to build the new home for your websites.
Step 1: Provision and Install CWP
After provisioning your new VPS, log in via SSH as the root user. The CWP installation is straightforward. Execute the following commands to get started:
cd /usr/local/src
wget [http://centos-webpanel.com/cwp-el7-latest](http://centos-webpanel.com/cwp-el7-latest)
sh cwp-el7-latestThis will begin the CWP installation. The process takes some time. Once complete, you will receive a congratulatory message with your CWP login URL and credentials.
Step 2: Configure Basic Settings
Log in to the CWP admin panel on your new server.
- Navigate to CWP Settings > Edit Settings and configure your hostname and other basic server details.
- Set up your primary nameservers if you are managing them via CWP.
Phase 3: The Migration Process
The easiest and most reliable way to migrate is using CWP’s built-in migration tool. It automates the transfer of user accounts, files, databases, and more.
Step 3: Initiate the CWP-to-CWP Migration
- Log in to the CWP admin panel of your new server.
- Go to the left-hand menu and navigate to CWP Settings > CWP to CWP Migration.
- Enter the required details for your old VPS:
- Old Server IP Address: The public IP of your old VPS.
- Old Server Root Password: The root password for the old VPS.
- CWP Admin Port: Usually
2031.
- Click the “Get Accounts” button. The new server will connect to the old one and pull a list of all user accounts.
- Select the accounts you want to migrate and click “Start Migration”. CWP will now handle the entire data transfer, including all files, databases, and configurations for each selected account.
Step 4: Manually Migrating Data (If Needed)
In rare cases, the automatic tool may face issues. Here’s a brief overview of how to manually transfer the most critical data.
- Files and Folders: Use the
rsynccommand for an efficient and robust file transfer.rsync -avzP -e 'ssh -p 22' root@old_server_ip:/home/ /home/This command will sync the entire
/homedirectory from the old server to the new one, preserving permissions and ownership. - MySQL Databases: Use
mysqldumpto export databases from the old server and import them into the new one.
Phase 4: Post-Migration Tasks
The migration isn’t complete until you’ve verified everything is working correctly.
Step 5: Test and Update DNS
- Verify Functionality: Log into the CWP on the new server and check a few accounts. Can you access the files? Are the databases there?
- Update DNS Records: The final and most critical step is to point your domain’s DNS records to the new VPS’s IP address. This is usually done through your domain registrar or DNS provider.
- Test Websites: Use a DNS propagation checker to see if the changes have been applied globally. Then, visit your websites to ensure they are loading correctly and securely on the new server.
