How to upgrade from Clipone theme (Boot strap 3) to a compatible boot stripe 5 theme

We have used clipone (Boot strap 3 theme) for several years. We have to upgrade our portal to bootstrap 5. what are our options?

As it’s no longer supported you are limited in terms of options - probably the best bet is to hire a (capable) freelancer to help but you’d want them to assess the work as it may not be that straight forward

If you’re interested in. I’m available for freelance work.
