i'm looking at somebody's site, can't really see how it's connecting. no _config.php or _ss_environment.php

wmk

SS4 has .env or Environment Variables, but afaik that's it

if there isn't db details in config.php, and there isn't a __ss_environment.php file, is there anywhere else a SS install will look for those details?

hmm, upgrade docs are pretty good, with old code and new code. There is also an upgrader tool that gets you started, https://github.com/silverstripe/silverstripe-upgrader

I've looked at upgrade notes - but I'm kind of looking for a "if you're used to 3.x here's what you need to know" type of guide

While I'm here - is there a good doc anywhere that highlights key differences between 3.x and 4.x ?
