Do I need SSL for a domain that has a 301 redirect to another site?

Question

Search Engine Optimization

There was a site https://site.ru (worked with an ssl certificate). I had to move to another domain https://site.club . Set up a 301 redirect. And now you need to renew the ssl certificate for the old domain (site.ru). Tell me, please, is it necessary to do this? Do I need a working ssl certificate for the old domain on which a 301 redirect is configured via htachez to a new domain? What is the right way to keep the link and weight in the eyes of search engines? Thank you.

Answer 1

In order to send instructions about the redirect to the user, you need a working data transfer channel.
In the case of HTTPS, the channel must be encrypted. Without an SSL certificate, the encrypted channel will not open.
Conclusion - an SSL certificate is needed.
