upgrading PHP on AWS instance

Hi,

I am getting messages in my admin tool that we need to upgrade our php. Since our install is on AWS, the recomended upgrade path there is to launch a new instance with the upgraded stack, php, and mysql.

I have done this and we now have an instance that is running mysql 7.0.2 and mysql 5.7.9. I uploaded the dir structure to my old instance and now I am wondering what to do next.

Can you outline next steps to:

1) get the DB imported
2) change config files to now sun on new server

thanks,

Jilll
