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.
