Hello Debian-users,
I have been delayed with upgrading my debian distro, and want to upgrade
to 12. According to the documentation, I should remove all non-debian
applications first, before upgrading. Almost all the applications I use
are non-debian (postfix, dovecot, apache, mysql, etc..), so it almost
makes it seem like I should just do a full new install??
I have been running a mail server, webserver, cloud (nextcloud), etc...
for the past decade, updating as time went along. However, for personal
reasons, I have let this slide longer than I would like to admit, so now
it's time to "get it done."
I was planning on backing up everything (via Clonezilla) so I would have
a "reliable backup," but that only half helps, because I would still be
back where I started from. Here...
I have done upgrades in the past, 8->9, 9->10, etc..and with a little
pain was just able to upgrade the system without removing previous
versions, and tweak some files that didn't work anymore.
Thinking out loud, I guess best bet would be to backup the systems most
important to me (outside of clonezilla), and just re-apply the
configuration files after a re-install of the required software systems?
So, now I guess my question becomes...ultimately:
"What is the difference between upgrading my system (after remove all
non-debian apps) and simply doing a brand new, clean install??"
"Is one better than the other??
Thanks, and Happy Holidays.
