Switching WordPress hosting providers is a pivotal moment for many site operators. But the process doesn’t end with migrating your files—it hinges on correctly updating DNS settings to ensure uninterrupted access for users.
DNS changes are required whenever you move your WordPress site to a new host, and the process varies depending on whether you manage your DNS records or your old hosting provider does. Each approach requires precise steps to avoid downtime and data loss.
Updating DNS When You Manage Your Own Records
If you manage your own DNS records, the responsibility lies with you to configure them for the new hosting provider. Here’s a structured approach to follow:
- Migrate your site and test it: Begin by transferring your WordPress files and database to the new hosting provider. Many providers, like Pressable, offer staging URLs for testing before DNS changes take effect.
- Institute a content freeze: Halt all activity—posting, commenting, purchasing—on the old site. This ensures that no data is lost during the final migration.
- Migrate again and test: After freezing content, copy the latest updates to the new host. Tools like VaultPress simplify this process. Thorough testing ensures everything runs smoothly.
- Update DNS records: Point the A records for your domain to the IP address of your new WordPress site. Ensure both www and non-www versions of your domain are updated.
- Wait for propagation: DNS changes take time due to caching by DNS servers. Typically, propagation completes within a few hours, though it can be faster.
Managing the process carefully prevents disruptions and ensures users seamlessly access your WordPress site at its new home.
DNS Updates When Your Hosting Provider Manages DNS
The process differs if your current hosting provider controls your DNS records. In this scenario, you’ll need to update your nameserver (NS) records to point to the nameservers of your new hosting provider.
NS records are maintained at the domain registrar where you purchased your domain. This is true even if your DNS is hosted elsewhere. Once updated, your new hosting provider can manage your A records, directing users to the correct IP address of your site.
Although simpler than managing DNS yourself, this approach requires careful coordination with both your old and new hosting providers.
What To Do
- Site Operators: Ensure staging URLs are available from your new host for pre-DNS testing. Use tools like VaultPress for backups and migrations.
- Developers: Double-check A records and NS records before propagation begins. Coordinate with clients to freeze content during migration.
- Agency Owners: Plan DNS updates around low-traffic periods to minimize customer disruptions.
