While upgrading should be an option, just don’t do it as a first step. Changing any dependency comes with risks and moving from version 5.5 to 7.2 of anything screams danger to me.

Sure, there are times when it’s going to work out for you but you should at least have narrowed down your issues before you go down that path.

I mean, it can be fairly safe. When I moved from 5 to 7.0 I simply left the PHP-FPM configuration for 5 around and 5 itself installed. It still is.

I can just spin up PHP5, 7.0, 7.1 in case anything goes wrong without delay.
