Why Website Migrations Go Wrong (and How to Avoid It)

Migrating a website to a new hosting provider sounds daunting, but with the right approach, it's very manageable. The most common mistakes — losing data, extended downtime, broken links — are almost entirely avoidable if you follow a structured process. This guide walks you through each stage.

Before You Begin: Preparation Checklist

  • ✅ Set up your new hosting account and note the server details (IP address, FTP credentials, cPanel/dashboard login)
  • ✅ Identify everything that needs to move: website files, databases, email accounts, SSL certificates
  • ✅ Note your domain registrar login — you'll need it to update DNS later
  • ✅ Choose a low-traffic time to perform the migration

Step 1: Create a Full Backup

Before touching anything, create a complete backup of your current site — all files and any associated databases. Most hosting control panels have a one-click backup tool. If yours doesn't, use an FTP client to download all files and export your database via phpMyAdmin or a similar tool. Store this backup somewhere safe and separate from your hosting account.

Step 2: Transfer Files to the New Host

Upload all your website files to the new server. Options include:

  • FTP/SFTP: Use a client like FileZilla to upload files directly to the new server's public directory (usually public_html or www).
  • Migration plugin: If you're using WordPress, plugins like Duplicator or All-in-One WP Migration can package and transfer your entire site.
  • Host's own migration service: Many hosting providers offer free migration assistance — worth asking about before doing it manually.

Step 3: Migrate Your Database

  1. Export your database from the old host (via phpMyAdmin: select your database → Export → Quick → Go).
  2. Create a new database on the new host via its control panel.
  3. Import the exported SQL file into the new database using phpMyAdmin on the new host.
  4. Update your site's configuration file (e.g. wp-config.php for WordPress) with the new database name, username, and password.

Step 4: Test Your Site on the New Server (Before Switching DNS)

This is the step most people skip — and it's the most important one. Before pointing your domain to the new server, test the site using the new host's temporary URL or by editing your local hosts file to preview how the new server responds. Check:

  • All pages load correctly
  • Images and media appear
  • Forms and contact pages work
  • Any e-commerce or login functions operate properly

Step 5: Lower Your DNS TTL

Before changing your DNS, reduce the TTL (Time to Live) on your domain's DNS records to a low value (e.g. 300 seconds / 5 minutes). Do this 24–48 hours before your planned switch. This ensures that once you update DNS, the change propagates quickly worldwide rather than taking up to 48 hours.

Step 6: Update Your DNS Records

Log into your domain registrar and update the nameservers or A record to point to your new host's IP address. DNS propagation typically takes between a few minutes and a few hours with a low TTL set.

Step 7: Keep the Old Hosting Active for 48–72 Hours

Don't cancel your old hosting immediately. Keep it active for a few days while DNS propagates and you confirm everything is working perfectly on the new server. Once you're confident all traffic is routing correctly, you can safely close your old account.

Common Mistakes to Avoid

  • Skipping the test phase: Always verify the site works on the new server before flipping DNS.
  • Forgetting email accounts: If you run email through your host, make sure email is configured on the new server too.
  • Cancelling old hosting too soon: DNS propagation takes time — keep both active during the transition.

Final Thoughts

A methodical approach is all that separates a smooth migration from a stressful one. Take your time with each step, test thoroughly, and keep your old server running until you're certain the switch is complete. Most migrations, done properly, result in zero meaningful downtime for visitors.
