How to migrate from Wordpress to Grav? (non-developer)

Hi there!
I have a site with lots of pictures in it and a blog section with a few posts. I want to migrate from Wordpress to Grav without losing any information and backlinks but I don’t know how to. I have seen that there is a plugin wp2grav but don’t know what to do after archiving the files.

So how should I start? I have 2 domain names, one of which I do not use… Should I install Grav on the unused domain and after that change the domain name or I should delete Wordpress, install Grav and add the files? Which means the site will be down for that period and I do not like that option because it can be down for a month if I mess up with this. :slight_smile:

I already have a folder with Grav in it on the hosting. Can I just move it?
I post an image to show the structure… My current visible website is in “wordpress”

Forgive me for my stupid questions. I have never installed a website but I have made simple changes in the code of my previous Zenphoto site and I think I can do it with a little help from you. :blush:
