I created an upgrade script based on something I found a few years ago

I thought I'd ask the Debian user brain trust to comment/critique the
scripted steps. So here they are:
############### Start

The lines for the security mirror has changed on Bullseye.

The script does not bail out on command failure, you might want to
takecare of that if you automate this process by way of a script.
That is all I can say on the cmds.
If I may, for a fiew servers I would do it manually instead of blindly
using a bunch of commands.
If you need to automate this process, you should familiorize yourself
with something like Ansible or in anycase a more robust solution.
For upgrading Buster to Bullseye, I used:
$ apt-get update
$ apt-get upgrade
$ apt-get full-upgrade
For better or worse, Debian let you upgrade or reinstall from scratch.
