Hi, quick Q for the experts :). I am currently on Invision 4.4.10 (i know, old, etc... life and work have gotten in the way of upgrades the last 18 months during Covid). We have a 20M post site so we want to be careful on upgrading. We plan to upgrade on 4.7.1 (or .2) once any remnant bugs are fixed. So maybe in a few weeks.
Currently we have the following config:
PHP: 7.3.33
MySQL: 5.7.38
Redis: 5.2.1
I'm not sure on PHP/MySQL version support between 4.4.10 and current. Are there any suggestions on the upgrade order? Ideally I would love to upgrade Invision the normal way with the above server config and then upgrade PHP/MySQL after that... But somewhere I read the min version supported by Invision 4.7 was PHP 7.4... Is that true?
Thoughts appreciated!
