How does the promotion of a non-primary mirror affect the promotion of the main one?

Question

Search Engine Optimization

The task is to transfer the link weight to the client's website and at the same time, upon termination of the contract, to keep the entire link mass.
The idea of ​​the solution is as follows: bind an additional domain (mysite2.ru) to the site (mysite.ru), make an alias (alias) out of it, set up a 301 redirect to the main domain name, in the Host directive and Yandex.webmaster, register the client's domain name as the main mirror (mysite.ru). Create a link mass to different sections of the site with links in which a non-main mirror is specified as a domain, for example mysite2.ru/catalog/
Question: will the weight from the link mass to the non-main mirror (mysite2.ru) be transferred to the main domain mysite.ru?

Answer 1

Good afternoon. Colleagues, why do you need to be "harmful" like that, because the client pays you for high-quality promotion, you lay a budget for the link, why "blame" it after?
Essentially - yes, the weight will be transferred with some loss. The scheme will work.
