By default, Plesk does not include a built-in option to export DNS records.

If your Plesk hosting allows you to install extensions, you can try installing the Transfer of DNS Records extension, which may provide the ability to export your DNS zone in BIND zone file format.

Note: The availability and functionality of this extension depend on your Plesk hosting environment and configuration. It may not be available or supported on all Plesk hosting packages.

If you're unable to use the extension, you'll need to manually copy your DNS records or contact your hosting provider for assistance.
