The maximum PHP version for 1.12.2 is 7.4. The minimum PHP version for 2.x (and the installer) may be higher than that, so you will likely need to switch PHP versions at this point. See Requirements for the current PHP requirements.
Now we have done preperations, we can start the real upgrade process!
