If I considered mailinabox an install-only script, and just updated my packages (through apt) and nextcloud apps/version (I unlocked admin), would there be any major ramifications from that? Assume that I have my setup the way I like it and may not necessarily want any real changes that might occur from the MIAB installer. I do have S3 storage set up in my nextcloud config as well as the preview generator Nextcloud app. I know that those are not supported, but I also do not want to run the MIAB update script and reset say my S3 storage or something.
Side question, if I added php 7.3 is there anything in place that would inherently break? I would prefer to use the Nextcloud Mail app rather than roundcube as I can see my calendar there.
Just for some background: I’m moving from (MIAB on VPS with ONLY using the mail function + Nextcloud on a home server using contacts/calendar/files) TO (One vps, using MIAB and moving my Nextcloud functionality to the built-in version - using S3 for my storage). I’m aware of sqlite and vps performance and how it affects me.
