I installed 8.6.4 a few months ago and there’ve been a number of versions of core that have come out since then. I want to upgrade, but do I have to do it sequentially? Like, first do 8.6.4 to 8.6.5, then to 8.6.6, etc., or can I just back things up, overwrite with 8.6.newest, and then copy back in the key parts of settings.php or .htaccess and it should work?
I have tried to get composer working and looked at drush, but for various reasons this isn’t working. Am opting to just do the manual upgrade — but hoping I don’t have to do this one by one by one.
