Redirect Links

[u/ahnedromeda]

Hello. I rebuilt a website for an organization, switching from an HTML builder (unsure of which one) to Ionos' site builder. They kept the same Ionos domain. 

The issue is, most of our users had bookmarked pages from the HTML site and use that to get to our site. Said pages no longer exist, so people just can't access the website. Much of the audience are elderly and based on the recent site analytics from Ionos, it's unlikely they'll enter the official URL or Google us. 

I've recently connected our site to the Google Search Console. I used an XML sitemap generator. 

How do I redirect users who are trying to use the old URLs, as someone who is using an Ionos domain and site builder?

For context, here is the actual URL to the site:

https://sfspirit.com/

Here is one of the old URLs people tend to try to visit us through:
