Migrate to a multi-tenant distribution

If you have a CloudFront standard distribution and you want to migrate to a multi-tenant distribution, follow these steps.

To migrate from a standard distribution to a multi-tenant distribution

  1. Review the Unsupported features.

  2. Create a multi-tenant distribution with the same configuration as your standard distribution, minus the unsupported features. For more information, see Create a CloudFront distribution in the console.

  3. Create a distribution tenant and add an alternative domain name that you own.

    Warning

    Do not use the current domain name that's associated with your standard distribution. Add a placeholder domain instead. You will move your domain over later. For more information about creating a distribution tenant, see Create a CloudFront distribution in the console.

  4. Provide an existing certificate for the distribution tenant domain. This is the certificate that will cover the placeholder domain and the domain that you want to move.

  5. Copy the CloudFront routing endpoint from the distribution tenant detail page in the console. Alternatively, find it by using the ListConnectionGroups API action in the Amazon CloudFront API Reference.

  6. To verify domain ownership, create a DCV TXT record with an underscore ( _ ) prefix that points to the CloudFront routing endpoint for your distribution tenant. For more information, see Point domains to CloudFront.

  7. When your changes have propagated, update your distribution tenant to use the domain that you previously used for your standard distribution.

    Important

    This resets the cache key for your content. After this, CloudFront starts caching your content using the new cache key. For more information, see Understand the cache key.

  8. Update your DNS record to point your domain to the CloudFront routing endpoint for your distribution tenant. Once you complete this step, your domain will be ready to serve traffic to your distribution tenant. For more information, see Point domains to CloudFront.

  9. (Optional) After you successfully migrate your domain to a distribution tenant, you can use a different CloudFront managed certificate that covers the domain name for your distribution tenant. To request a managed certificate, create a separate TXT record to issue the certificate and follow the steps here in Complete domain setup.
