Will such a site transfer from Joomla to WordPress work without losing positions?

Question

Search Engine Optimization

Hello.
There is a task to transfer a site from Joomla to WordPress.
The site has only a few pages (about 10).
I plan to create a WordPress site on a subdomain with identical texts and design. Save the look of the links.
Then just transfer to hosting. How will this affect output?
On the one hand, the content and links will not change. But I decided it was better to ask again.

If you really do everything correctly, it will not be reflected.
Do not forget to close the subdomain from the index, and vice versa, when you transfer to the main domain, open indexing.
