In our eyes – installing SonarQube in AWS is not meaningfully different than installing on-prem. The Requirements are the same, as well as the installation instructions.
v7.4 is an outdated version of SonarQube. The minimum supported version of SonarQube is v7.9 LTS – you should consider upgrading as a part of this move.
I assume you are also moving the Database to AWS – you should probably do that first (such instructions will be specific to your database provider, and not specific to SonarQube), and then install a new SonarQube instance that points to that database!
You’ll also want to make sure that any resources that communicate with your SonarQube server (your build servers, for etc.) are able to access the SonarQube server at its new home.
