XF 2.1 Importing link from my old smf

[carajo]

Hi, I'm having trouble creating the redirect from a url from my old smf forum to the new url on xenforo.

I have tried it from the .htaccess file, adding the line: Redirection 301 /old url https://new url

and I can't get it to work.

How can I do it?

old url:

Oops! We ran into some problems. | Foro de Psoriasis (lapsoriasis.com)

correct url:

Remedio Natural - Salinas de naval reportaje fotográfico. Para psoriasis y otras enfermedades. | Foro de Psoriasis (lapsoriasis.com)
