Redirect website (keep seo intact)

Hi, my client has a website on weebly and she has a good seo atm (but the website is sh*t). I want to create her a new website on wordpress but i’m wondering if she will lose her seo because i create a new website on wordpress.

Should I just redirect people when they click on her old website to the new website (new domain)?

What would be the best way to keep her seo?

Thank you
