How to upgrade to PHP Version 7.2?

[Karooo]

Hello - I am unfortunately somebody with Little understanding - I do urgently Need help as my Provider is changing the Supported PHP Versions to: 7.2

My provider's advise is the following:

All old PHP-Versions will be discontinued soon and I will automatically get upgraded to PHP 7.2

As my Webshop is not compatible at the Moment with PHP 7.2 (its currently operating on 5.6)
this will DESTROY my whole shop System!

I do Need help with the following:

How can I actualize my CMS onto PHP 7.2 including all
PlugIns, Themes
They must be compatible with the new PHP
Version (7.2)
