Any PHP 7 Hosting that help with migration?

I am thinking moving my websites to PHP 7. I heard that it outperforms the previous versions, which is what my websites are currently using. I have seen some impressive benchmarks of PHP 7 on WP, Drupal, Joomla, etc. So, I am certain that moving my websites to PHP 7 will significantly improve their performance. My problem is that I am not really experienced with website migration.

Can anyone recommend me a PHP 7 hosting that will help me with migration?
