Two domains for one Bitrix site?

Question

HTML

I want to purchase another domain for my site and set it up as a secondary one. That availability was both from one and from other address. Bitrix.
The second question is, is it possible to somehow synchronize goods on different sites on Bitrix (upload goods to one site, and then upload them to another through excel?) Are there any other options? If you use this option, which modules are needed

Answer 1

In xml format, make an upload, import it on another site, there will also be a folder with pictures attached. First backup the entire site.
/bitrix/admin/iblock_xml_export.php?lang=ru
As for the first question: two domains can look at the same site and will display the same content. But what do you want to achieve with this?

Answer 2

If you need one database on different sites, then look towards multi-site

Answer 3

you can’t make a copy of the site, duplicate content is bad for SEO, redirect from the secondary site to the main one, which will be the main mirror.
