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.
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.
