Do I need 301's if I use HSTS in HTTP to HTTPS migration?

[KevinBudzynski]

Just wondering if this was strong enough signal to search engines that we don't need to write a 301 rule in .htaccess.

I have been using backlinko (Brian Dean) as a reference, and as I see it was a mistake. I didn't know Fili Wiese and as I see he knows what is he talking about.....thank for reply

Thanks Roman. I contacted Fili Wiese who has the best article on HTTP to HTTPS migration and he was graciously answered me back in minutes and he replied:

"HSTS is for the browser and the user, not the search engine. So yes, you do need to do 301 redirects."

Thanks!

In a simple word, Yes it can hurt your SEO

Excessive 301 Redirects to Page: Links coming from 301 redirects dilute
some (or even all) PR, according to a Webmaster Help Video.

Links from 301: Links from 301 redirects may lose a little bit of juice compared
to a direct link. However, Matt Cutts says that a 301 is similar to a direct link.
