I have had a SOHO network with a couple Debian machines for ~15 years. 
My primary goal is reliable operations.


Doing a major version upgrade in place without understanding all the 
issues and risks involved has not work well for me.  And, I estimate the 
learning curve to be non-trivial.  Instead, I pursued the following:

1.  Put my drives in mobile rack drawers, put racks in my computers, 
and/or put trayless racks in my computers.

2.  Take good system administration notes for every machine.

3.  Place notes and all modified configuration files into a version 
control system.

4.  Invest in additional equipment and learning to implement robust 
backup, archive, and image procedures.

5.  Keep at least one spare machine available at all times.


These allow me to install, repair, upgrade, etc., computers within an 
acceptable (and predictable) effort level.


When I want to do a major version upgrade on a computer:

1.  Backup and archive the data and configuration files.  Remove the 
system drive and take an image of it.  Save drive.

2.  Get a fresh system drive.  Wipe and test it using the manufacturer's 
diagnostic utility.  Insert into machine.

3.  Download the latest Debian Stable and burn to media.  Do a fresh 
install.  Update and upgrade.  Install desired software.

4.  Edit configuration files and migrate settings by hand.  Restore data.

5.  Integrate into backup, archive, and imaging processes.
