Moving a whole website from sharepoint to Zoho

Hi guys,
I did a search on this and none of the information I got was clear to me.
We have a big website here in Japan, it's a sharing community for English teachers where teachers of English in Japan can share activities and lesson plans with others. It's managed by volunteers and no one is a programmer nor webdesigner.

For many years we used sharepoint/ office 365, but now the site has grown a lot and became hard to manage the pages on the actual system.
Well, is there a way of transferring/ cloning the whole website to Zoho?

This is the website:

www.englipedia.net

Zoho seems easier to work with than 365.

Thanks,

Tony
