Creating an alias is very simple – you add a new item and alias and the real path of the URL.
For example, you page: https://мой_сайт.ru/статьи/home.html is outdated and you need to replace it to the new address, which is the link: https://мой_сайт.ru/статьи/главная.html.
Click the Create button.
In the From URL put the old value relative to site root, i.e. /статьи/home.html and the URL To insert a new link in full, ie https://мой_сайт.ru/статьи/главная.html
Redirect, depending on destination, set in its discretion. If it is constant, it stays in position 301 (Moved Permanently).
