Indeed, if you have a modern codebase on 5.6 then moving to 7 is very straightforward.<p>In anything I&#x27;d written in the last 2 years I didn&#x27;t have to change any code at all, just upgrade, run unit tests, do some sanity checks and deploy.<p>Performance increases was immediately noticeable on both response times and server loads.<p>One of the easiest wins I&#x27;ve ever had :).
