When I duplicate a site, are the `_id`s if CMS items kept the same?

I have a site with CMS enabled, and the CMS is full of items. Each item has a unique identifier (_id).

I want to duplicate the site, but want all the CMS items to have the same _ids.

Is this the default behaviour, or will they get different _ids?

They would get new unique ID’s.

Thanks @webdev. Next question: can I create them with the same id or would that violate a uniqueness constraint?

The _ID value is a read-only GUID. So no.

Ah, thanks. I thought that it was possible to set that, looking at Webflow CMS API Reference.
