2.3.0.2 php 7.4

I have OC 2.3.0.2 installed and it has been working great! The current version of PHP is 5.6. Can I upgrade the site to 7.4 without running into any problems? I'm using the default theme and several aftermarket extensions.

You need to replace the OC Default system/library/encryption.php
file with the one linked below, that's all it usually takes:

And when it comes to the Extensions installed, you will find out, I guess!
But usually, they should work, if you don't use something really special.
Cross-check the content of Condor2's updated Github Version 2.3.0.2 with yours,
and you probably find some fixes, which also could be included in your stock 2.3.0.2,
just to make sure, to have what it's Creator CONDOR2 (xxvirusxx) found and changed
on misses.

Good Luck!

That repo was removed from my github account.
I have only this version

Without knowing the extensions you're using, I would suggest trying PHP 7.2

You can change the PHP version and thoroughly test your site without the need to backup before doing so. If it doesn't work, you can bump down to a lower version.
