How (is it possible) to transfer your self-written yii2 site to bitrix (the old site is made on bitrix, i.e. instead of the old one, put a new one written in yii2)?

Question

Yii

Good day toasters and toasters!
A friend has a site on Bitrix (and of course a domain was bought for it). He asked me to make a good site - a business card. Made (not on Bitrix). The task is: to transfer your site to Bitrix, or (if it is expensive, stupid or not possible) - to transfer the domain from Bitrix (for example, to nic.ru) and screw everything on your hosting.
Question: is it possible to transfer my site (on yii2) to a friend's Bitrix (and if so, how is it done)? And if not, then pick up the domain and start everything from a normal hosting?
ps I have never created sites on Bitrix, so I don’t know what they eat it with. I have always used hostings nic.ru and majordomo.ru and there were no issues of creating or transferring sites. And here you need to deal with the old site on Bitrix (instead of it, put a normal new one on yii2) so that it is under the same domain

Answer 1

Rewriting a finished site from one framework to another ... Why? They did it, they did it.
Change domain registrar? What for? Hoster? What for? If the client has no claims to the registrar and hoster, then there is no point.
In your situation, the rejection of Bitrix in favor of another system is obvious. So it must be removed and another deployed in the same place. Of course, if the client does not mind. Usually, the client does not care (for a business card, for sure).
Well, sometimes the old site is kept on the old subdomain. Then, if the tariff allows, deploy two sites on the hosting (one on Bitrix, the other on yii2).

Answer 2

It's not entirely clear what you need... Do you want to use Bitrix CMS, but also transfer a business card? Or do you just need a business card? Do you need Bitrix at all?
or do you just need to leave the host?
If you just need to make (only) a business card, why not put Yii instead of Bitrix?
If you bought a domain - it's yours. It can be taken to another hosting.
Usually, an application for relocation is written (a scan or the like is sent) in more detail and the hoster to which you plan to move will be happy to advise you (sometimes it will also help)

Answer 3

If you want to transfer a domain to another registrar, then contact the site where you want to transfer the domain. They will advise what documents are needed or even send a request for you.
If you want to install yii2 instead of Bitrix on the same server, check with the hoster if this is possible.

But it's better to contact the hosting technical support and clarify.

Answer 4

You ask whether it is possible to "make a brick house wooden." Answer: Yes, you can, but the labor costs make this process inappropriate. So you need to take Bitrix and make the same site on it. But to be honest, I don’t understand why to make a wooden house out of a brick house.
