Domain Migration with Pre-Configured Mode

When migrating an actively used domain to Conversant CDN, it is often necessary to enable CDN acceleration without interrupting existing services. To achieve this, the domain must first be preconfigured in the CDN service through the portal or API.

If you plan to enable the Auto Certificate, use Pre-Configured Mode to complete domain ownership validation by configuring the provided CNAME record on your DNS provider. Pre-configured mode allows you to verify domain ownership through a dedicated validation domain without modifying the domain’s current DNS resolution. This ensures that the existing domain remains unaffected during the certificate issuance process.

Once the certificate has been successfully attached, you can update the domain’s DNS record to point to the accelerated domain’s CNAME record to complete the seamless migration.

Steps:

Go to Domains and click Add Domain. Enter the Domain Name into the existing domain (for example, www.example.com) and specify the Origin URL (IP address or origin domain). Click Save.
Go to the configuration page of the newly added domain. Under SSL Certificate, click Attach, then select Auto Certificate.
Review the CNAME record provided under Pre-Configured Mode, for example:
```
_acme-challenge.www.example.com CNAME www.example.com.cert-validate.swiftserve.com
```
Configure this CNAME record on your DNS provider.
Use tools such as dig to verify the CNAME record has taken effect:
```
dig CNAME _acme-challenge.www.example.com
```
Once the record is active, go back to the domain’s SSL Certificate section, select Pre-Configured Mode, and click Attach.
Wait for the certificate issuance to complete (typically 10–15 minutes). You can check the status under the SSL Certificate list.
After the certificate becomes active, go to the Basic tab of the domain and copy the provided CNAME value. Update your domain’s DNS record on your DNS provider to point to the accelerated domain, for example:
```
www.example.com CNAME edge.conversant.swiftserve.com
```
Go to Analytics > Monitoring to verify traffic metrics (bandwidth, request count, cache hit ratio, status codes) after the migration.
