How do I Update to

My site is on hosted by WESTHOST and I need to update the newer version. I have downloaded the version but I'm at a loose how to go about updating my server at WESTHOST.
My current version won't work due to a change in php 5.?? to 7.??.
Any help would be greatly appreciated.

What version is your current website? Anything that is 5.6.x or 5.5.x can not be directly updated to 5.7+ the site will need to be rebuilt.

Unfortunately, yes. There is no upgrade path from 5.6 to 5.7, there is a migration tool here -

But there are no tools for porting a theme or custom blocks, and your purchased add-ons will have to be repurchased for the new version.
