Migrate my site from a bit older php and mysql to newer

Hello, Tom and forum visitors!
First, thank you so much for GP premium theme. Love it!

I have a question, I made a site on GP prem + elementor and it runs on my bluehost account on php 7.0.12 and mysql 5.6.32

But my client has MYSQL 5.7.18 , Apache 2.4.27, OpenSSL – 1.0.2L, PHP – 7.1.7

What should I do to successfully migrate it there. I use All in one gp migtation plugin.

Thank you!
