How to move a site to another folder with a different domain?

Question

1C-Bitrix

Greetings!

In general, there was a site, it had a domain, a template like cool everything was done, there were folders, the catalog was filled, the menu was built and everything was done.

Now the task was to move this site to a subdomain, and leave only Landing 24 on the main domain.
In general, Landos works fine, we did everything for multi-domain through the console, registered new settings for the Site List.

The site opened but at first it was crooked, I transferred all the packs that were on the previous site (stupidly copied), the site partially worked, but there were errors in the console, as if something was not connected + the content was displayed crookedly or not displayed at all + the entire menu broke, stopped displaying links, question... what went wrong?

And how is it correct to transfer such sites to another folder with a different domain?

P.S.
And this is if the authorization is in the admin panel, and if you open it in incognito, then it generally displays the Attorization form instead of the main content
